ORegen Waste Heat Recovery Cycle: Development and Applications Andrea Burrato GE Oil & Gas The rising concern for the role of CO2 emissions with respect to global warming and the climate changes combined with the increase in energy demand spurred by developing nations that is foreseen over the next fifteen years has recently turned attention to potential CO2-neutral energy supply solutions. The combustion of hydrocarbons is the process with the highest impact on CO2 and NOx emissions. CO2 generation is directly tied to the efficiency of energy conversion from hydrocarbons. Gas Turbine technology has been used in industrial applications for powering plant infrastructure and gas transportation since the early 50s. One of the most effective approaches to increase the efficiency of energy conversion is waste heat recovery considering the large amount of energy that is discharged in the atmosphere by simple cycle gas turbines whose efficiency in the best case is around 40%. Modern plants designed for base load power generation and equipped with gas turbines typically employ a bottoming cycle. The standard bottoming cycle is the Rankine cycle (RC) that recovers the heat from the exhaust of the gas turbine. The combination of the two is referred to as a combined cycle. The present article introduces the Organic Rankine Cycle (ORC) developed by GE referred to as ORegen system for waste heat recovery from simple cycle gas turbines which operate at variable loads from 50 up to 100% in power generation applications located in areas where water is absent or scarce, overcoming the limitations of the traditional water/steam Rankine cycle when applied to gas turbines. The thermodynamic configuration allows modern plants to exceed 50% efficiency even though the gas turbine simple cycle ranges from 30 to 40%.

The 7 Deadly Sins of Filtration and Separation Systems in Gas Processing Units David Engel Ph.D. Nexo Solutions and Michael H. Sheilan P.Eng. Sulphur Experts Separation systems play a fundamental role in gas processing both for reliability and as enabling devices for enhanced throughput and process stability. In many cases these systems are the only and/or last line of defense to protect the plant from unwanted and detrimental contaminants. As plants are required to process gas with more contaminants (such as certain Shale Gas feeds) these devices are increasingly being required to perform under progressively difficult conditions. As we evaluate troubleshoot and improve many of these systems at a number of worldwide plant operations we have successfully identified many different failure modes in these systems with various degrees of severity. These can range from incorrect design to poor choice of physical location to errors in instrumentation and most critically erroneous or non-performing internals. A large set of these cases were combined and compiled into a list of the seven most common errors in filtration and separation systems applied only to gas processing operations. The effects of not having correct contamination control in gas processing operations quite often cause profound impacts in the vast majority of gas processing plants and are manifested as solvent contamination and degradation foaming fouling low reliably low efficiency increased maintenance and undesirable environmental emissions. All this leads directly to high operational costs and/or the inability to meet sweetening specifications. Each deadly sin will be analyzed and presented with actual plant cases. Each case is also analyzed for its effects consequences or ramifications and in some cases how the problem was successfully corrected.

Printed Circuit Heat Exchanger replacing Brazed Aluminium Heat Exchanger Robert Broad, Heatric Brazed Aluminium Heat Exchangers are the workhorse for the cold end of gas processing having multi-stream capability capable of operating with low temperatures differences fabricated out of a low cost material of construction with high thermal conductivity over a wide operating temperature. However they suffer from mercury attack and thermal fatigue so are prone to failing or worse depending on the mechanism. This has led several gas processing plants to investigate alternatives of which the Printed Circuit Heat Exchanger (PCHE) in stainless steel has proven to be a viable alternative. This paper highlights the differences between the two technologies including a cost comparison over the lifetime of the plant and ultimately shows the superior integrity and higher grade of material which leads to a much more reliable and safe solution of the PCHE is a worthwhile long-term investment using a case study of a real life replacement.

The Newly Developed HPRC and Wet Tolerant Compressor For Upstream Market G. Iurisci, M. Bertoneri, S. Falomi & A.Grimaldi, GE Oil & Gas The current enormous pressure on cost calls for new technologies that can simplify and reduce the number of equipment installed as well as saving space and weight. HPRC compressor is a technology that building on our compressor heritage enable GE Oil & Gas machine to deliver very high pressure ratio in one single casing. While Wet Tolerant is a technology injection in our compressor making them capable of continuous operation with consistent amount of liquid content (up to 5%LVF). Natural Gas production and EOR plant are increasingly done offshore making these new technologies very attractive both in terms of CAPEX and OPEX. The paper will illustrate as HPRC and Wet applied to real cases (studies) deliver huge amount of benefits and also how process can be re-engineered to achieve higher efficiency reliability simplification and finally drastically cut cost. The paper will briefly describe the two new technologies and the qualification path followed. The paper will present expected savings in terms of for both presented technologies:

footprint weight power absorbed.

A New Solvent for Acid Gas Removal - Screening Methodology and Techno-Economic Evaluation Bruno Delfort, Aurliea Wender, Thierry Huard, Nicolas Laloue, Sbastien Gonnard, Julia Magne-Drisch And Julien Grandjean, IFP Energies Nouvelles Gas operators are facing the challenge to remove the undesired acid gases and contaminants from ever more sour gases with ever more stringent specifications, which appeal the development of new technologies. The most important challenges on acid gas removal with an amine solvent are :

Reduce the cost of gas treatment and enhance energetic efficiency Enhance selectivity of H2S removal versus CO2 Achieve higher specifications in contaminants (e.g. COS) removal Over the past 5 years IFPEN has developed a leading research expertise to select a new solvent. Based on full integration between laboratory experiments and early evaluation of process performance, this method provides new insight on structure-property-performance relationship and reduces the time to market and the development costs. High-through put screening methodology has been used to benchmark over one hundred amines.

The final techno-economic evaluation has been performed for the three best candidates on three industrial representative study cases of todays challenges.

The new selected amine for industrialization represents the best compromise in terms of synthesis cost and gain of performance. It offers a significant gain in selectivity compared to the traditional MDEA process and reduces OPEX and CAPEX by 15% in the three cases

Diisopropanol Amine (DIPA) Reclaiming By Means Of Electrodialysis Technology For HSAS & Formamide Removal Fabrizio Pisanella Amines Global Services Since 15 years Electro dialysis is the only method to remove non-regenerable salts (HSAS) that does not have a direct impact on the operation of the amine unit. Amine is sent to the electrodialysis unit and is returned in exactly the same state except that the level of salts has been reduced. There is no need to modify the operation of the amine unit in any manner when the electrodialysis unit is on line. Electrodialysis units are also now available as fixed units for application were the growth rate of HSAS is constant. The use of reclamation technology such as electrodialysis is becoming a consolidated and popular method of controlling heat stable amine salts (HSAS) in refinery natural gas plant Carbon Capture amine solutions. Up until recently proper control of the level of heat stable salts was not considered a priority for many operators. Salt levels were often well above recommended levels. HSAS were essentially non-controlled. The concentration was controlled by the often-important losses of amines from various points in the amine system and by the resultant high quantity of make-up amine that was added to the units. HSAS levels now play important roles in optimising the energy efficiency of amine units are critical for the control of corrosion and are a factor in the amount of amine lost due to foaming.

Methanol Distribution in Amine Systems and its Impact on Plant Performance Anand Govindarajan, Ralph H. Weiland, & Nathan A. Hatcher Optimized Gas Treating Methanol injection into natural gas streams is commonly used to prevent hydrate formation and icing. Later when the gas is scrubbed the residual methanol enters with the gas and tends to build up in the amine treating system. Aqueous amines absorb most of the methanol present in the feed gas. This increases the solubility of other hydrocarbons and affects acid gas vapor-liquid equilibrium. Additionally significant amounts of methanol then enter in the acid gas fed to the sulfur unit causing catalyst degradation lowered sulfur recovery and higher sulfur emissions. Existing simulation tools do not allow for simulation of methanol in amine systems. Recently we introduced the ability to simulate methanol in amine systems on a mass transfer rate basis. This paper details how methanol distributes in amine systems it examines the effectiveness of a water wash stream upstream of the amine absorber and it quantifies the effect of methanol on reboiler energy usage in a typical LNG unit

The Impact of Elevated Acid Gas Recovery Temperature on Downstream Unit Operations - A Case Study Jon Lewis, WorleyParsons The recovery of flared gases presents a variety of design challenges often complicated by feed gas compositional uncertainty the presence of acid gas components and tight emission specification. This paper summarises a case study on a Middle Eastern flare gas recovery application where two approaches were investigated. The Base Case was a traditional approach using refrigeration to allow relatively cool operation of the amine systems in the acid gas recovery and SRU tail gas treating units whilst the Alternative Case considered warmer operation of these systems with no refrigeration. For the Alternate Case the impact on design of unit operations downstream of acid gas recovery was assessed with respect to product and emissions specification together with a CAPEX and OPEX assessment.

Innovative Adaptation of Ion Exclusion Chromatography (IEC) for Easy and Efficient Desalination Of Mono-Ethylene Glycol (MEG) Avinash Malhotra, Frames Group The amount of production water increases during the life-time of a field which increases the need for hydrate inhibitors. These hydrate inhibitors are recycled leading to salt buildup which is a challenging problem. The amount of salt increases along with the increase in the produced water flow due to producing wells longer. This paper has been written to present an innovative technique for desalination of the hydrate inhibitor. Mono-Ethylene Glycol (MEG) is injected in pipelines between the wellhead and the receiving facility to inhibit hydrate formation and corrosion. To recover and reuse MEG it has to be separated from the produced water. During this regeneration process the salts are generally not removed leading to a buildup of salts in the MEG loop. The accumulating salts will precipitate causing clogging and damage. An ideal desalination technology should prevent salt precipitation. Our innovative WISETM (Waste-free Inhibitor Salt Extraction) technology provides clean reusable MEG. Glycols and salts have different affinities for the resins specifically developed and selected for this technology. This enables the efficient separation of both components by means of chromatography. This is done by a proprietary Sequential Simulated Moving Bed (SSMB) in which a feed stream is pushed through a resin bed. Due to the different speeds of elution in this bed the output flow of salts can be extracted from the bed at a different time than the output flow of MEG. Due to an innovative switching scheme and multiple beds this leads to a continuous separation of salts and MEG. A major advantage of IEC is its inherent ability to remove both monovalent and divalent dissolved salts in a single step. This efficiently removes the destructive impact that divalent salts have in other processes. A buildup of divalent salts creates a viscous fluid. WISETM circumvents the buildup of divalent salts. Furthermore this technology can easily be introduced into an existing plant which is especially convenient to bring old wells back online. Operation of WISETM is very flexible and can be tuned to severely changing process conditions. Compared to traditional processes this system has higher reliability availability and lower maintenance costs and with an output of dilute salty water no chemicals are required nor produced.

An Innovative Technology for Natural Gas Sweetening by means of Cryogenic Distillation

Laura A. Pellegrini & Stefano Lang, Politecnico di Milano, Oldrich Mikus, Stamicarbon, and Barbara Picutti, Paolo Vergani, Guido Franzoni, Marco Lo Savio & Fabio Brignoli, Tecnimont The application of traditional chemical absorption of CO2 and H2S by means of alkanolamines is not competitive for natural gas sweetening when the amount of acid gas is high, because the energy required by these processes is proportional to the quantity of acid components to be removed.

On the other hand, the cryogenic distillation technologies can be usefully applied to process natural gas with any amount of acid components, since the costs are incrementally reduced, the higher the acid gas content in the stream.

In the amine washing separation methods, CO2 and H2S are recovered at low pressures (nominally 1-2 bar) and need then to be dried and then compressed for re-injection into underground storage; on the contrary cryogenic distillation technologies discharge the CO2 and H2S mixture as a high pressure liquid, with a commercial advantage when this stream is re-injected for storage into depleted reservoirs or for EOR purposes.

An innovative process based on a "dual-pressure" cryogenic distillation unit is proposed with its two sections (the high-pressure column for the CO2 bulk removal and the low-pressure column for the methane recovery) working across the critical pressure of methane and the SVL locus of the binary CO2-CH4 mixture. This allows a complete separation of CO2 and H2S from methane, while avoiding the CO2 freezing.

A dynamic simulation study has been developed in order to validate the process architecture and to define the unit start-up procedure, while a laboratory experimental campaign is beginning.

Carbon Dioxide Tolerant Nitrogen Rejection Reduces Cost and Emissions Adil Farooq, Adrian Finn, Ahmad Hosainy & Grant Johnson, Costain For commercial scale nitrogen removal cryogenic distillation is the only cost effective technology. Cryogenic nitrogen rejection produces a high purity nitrogen waste stream which can be vented to the atmosphere and achieves very high hydrocarbon (HC) recovery with low power consumption

Cryogenic nitrogen rejection processes which employ a pre-separation distillation unit can handle up to sixty times as much feed gas CO2 as processes which do not use pre-separation. This paper presents a new process that, through modification of an established, proven cryogenic nitrogen rejection process, allows up to about 2 mol% CO2 content in the feed gas to the cryogenic nitrogen separation process. This reduces capital and operating costs by eliminating or reducing upstream removal of CO2 and also eliminates the risks associated with handling and storage of chemicals typically required for CO2 removal.

Extending the Operating Life of a Major Gas Terminal Andy Hollins, ABB Consulting Over the last two years the operators/owners of major gas terminals have commissioned Asset Life Planning and Life Extension Studies. These terminals comprise a number of gas processing units varying in age from the relatively new (circa 10 years) to more than 25 years. In order to provide one of the necessary inputs for their longer term business planning processes the owners of these facilities have a requirement to determine the actions and investment required to sustain safe and reliable operation of the terminal facilities for time periods up to a further 25 years (i.e. a second life). This paper provides an overview of these studies. In addition to giving an outline description of the process followed the paper provides a summary of the following:

The benefits to the owners of undertaking the studies The significance of the various age related degradation mechanisms within gas processing

facilities The identification of gaps within current maintenance programmes Areas of concern requiring investment to sustain operations Short medium & long term actions to sustain reliable ongoing operation of the assets. Projection of the additional expenditures over the remaining lifetime of the assets. The overall context of the Life Study in relation to the eventual decommissioning dismantling and

remediation of the site.

The author has lead multidisciplinary teams delivering Asset Life Ageing and Extension studies for major operating companies spanning gas processing oil processing and petrochemicals.

The Use of Aminosilicones in CO2 Capture

Phil DiPietro, GE Global Research

Since 2008 GE has been developing an aminosilcone CO2 capture technology mostly as a part of collaborative research performed with the U.S. Department of Energy. The aminosilicone is a non-aqueous chemical solvent that offers interesting performance benefits compared to aqueous amines: lower corrosivity less steam use smaller footprint. The work performed to date has been focused on post combustion capture for greenhouse gas emissions mitigation and utilization for enhanced oil recovery. In October GE will conduct a pilot test of the aminosilicone CO2 capture system (400 kgCO2/hr) at the National CO2 Capture Center in Alabama U.S.A. The purpose of this paper is to explore the potential to apply aminosilicone technology to natural gas processing. The most salient performance advantage is that the aminosilicone solvent does not wet the process gas. This paper will present conceptual process diagrams of AGR with aqueous amines and aminosilicones and draw cost and performance comparisons.

Membrane Application for NGL Production Enhancement Taib Abang, Faisal D Al-Otaibi, Sebastien A Duval, Milind M Vaidya, Jean-Pierre R Ballaguet, Iran D Charry Prada & Ahmad Fadzil Mohammad Saudi Aramco Saudi Aramco has been exploring opportunities to increase C2+ natural gas liquids (NGL) production to meet Saudi Arabias internal demand. The production of non-associated natural gas entails removal of contaminants such as hydrogen sulfide, carbon dioxide and nitrogen to reach sales gas quality. In addition, despite the reduction of the gas heating value, it is financially attractive to recover NGL from non-associated gas. As far as CO2 removal is concerned, glassy membrane technology has been successfully utilized for a few decades. More recently, other types of membrane materials, for which the selective layers are in a rubbery state, are commercially available. Due to their permeability properties, these membranes can reject nitrogen and concentrate heavy hydrocarbons in the membrane permeate stream, which can be then routed to a cryogenic NGL recovery unit. The authors company conducted field pilot testing on rubbery membrane at one of its major gas plants. One of the main conclusions from the field pilot testing results is that this membrane technology can be utilized to increase C2+ NGL production for both wet sour gas and sweet dry gas. This paper describes a potential industrial application of rubbery membranes, for both wet sour gas and sweet dry gas, to increase the concentration of ethane plus in the feed of an NGL recovery unit. Various membrane configurations are presented with respect to process. The NGL production increment surpasses the additional constraints on compression and gas shrinkage. The study concludes that the deployment of membrane technology for both wet sour gas and sweet dry gas application to increase C2+ NGL production would be economically attractive.

New NGL Recovery Process Designs for Unconventional Gas Applications John Mak, Sabrina Devone & Brian Jung, Fluor Energy and Chemicals The recent significant drop in crude oil prices has lowered the gas producers interest on liquid recovery in gas plants. The economics of conventional cryogenic plants for NGL recovery becomes questionable. In addition the low ethane prices require most gas plants to operate on ethane rejection mode which consumes significant amount of energy. Thus the standardized cryogenic plant may not be the optimum choice today. Fluor comes up with an NGL design that can be installed in three phases that would meet the current economic threshold. In the first phase equipment is installed to remove heavy hydrocarbons to meet the pipeline hydrocarbon dewpoint and the heating value requirements. In the second phase a bolt-on unit is added for propane recovery which can typically achieve over 92% propane recovery and can be economically attractive even with todays low oil prices. In the third phase a second bolt-on unit can be added to recover ethane which may occur when the ethane export markets are established. This paper describes the three phase approach on NGL recoveries the design configurations and performance that can be achieved for various shale gas feeds. This design approach requires the minimum CAPEX for the shale gas production while preserving capability for future high propane and/or high ethane recoveries.

Innovative Process Scheme for Mercury Removal on Water Saturated Natural Gas Clotilde Jubin and Olivier Ducreux, Axens Elemental mercury is a contaminant of natural gas leading to HSE (Health Safety Environment) related issues and to corrosion in LNG (Liquefied Natural Gas) plants cryogenic exchangers. In recent gas plant designs the mercury removal units are implemented as close as possible to the production wells on gas saturated with water and hydrocarbons. Presence of liquids can have detrimental impact on adsorbent integrity and performances. A dual complementary approach can be considered with the use of a robust adsorbent focused on an optimized alumina technology combined with the implementation of an innovative energy-efficient solution for the reduction of relative humidity of gas. The advantages of tailored adsorbents have already been presented at 2014 GPA Europe Annual Conference while this paper is focusing on the interest of an innovative scheme based on process modeling heat consumption and economics calculations.

Water Content Assessment in Acid Gas Alexandre Terrigeol, CECA, Christophe Coquelet MINES Paris Tech, & Antonin Chapoy Heriot Watt University Natural gas is well known as the cleanest fossil fuel. Today it is estimated that more than 40% of the remaining conventional natural gas reserves are deemed to be acid i.e. containing significant quantities of CO2 and H2S. As the global consumption of natural gas is expected to steadily grow the demand will be met by sources such as sour/acid gas fields. In some specific applications that require cryogenic processes (LNG NGL recovery) this issue is commonly addressed upstream of the gas dehydration unit so that the gas is already sweet when arriving the drying section. In the other cases the effect of the acidic species on the gas water content is often not properly accounted for. An accurate appraisal of the water content is paramount for the sizing of dehydration units. There are several methods to estimate the water content: some of them are based on empirical correlations or on thermodynamic models. Herein we will focus on CO2 rich gas mixtures. This paper first explains why it is crucial to address the problem in terms of dehydration unit design and plant reliability. A comprehensive literature review from the public domain and discussion of mathematical methods or thermodynamic models used for water content estimation are presented. Finally a new correlation based on thermodynamic assumptions was developed and was tested by comparison with experimental data obtained with a new laboratory experimental set-up. This equipment uses a Tunable Diode Laser Spectroscopy (TDLS) with an accuracy of 1%.

Calculation of Hydrocarbon Dew Points Using Equations of State Andrew Laughton DNV GL The hydrocarbon dew point temperature is an important Gas Quality measurement in the Natural Gas industry - to ensure liquid formation does not interfere with operations. This paper discusses how a gas chromatographic analysis can be used to reliably calculate this - for example using the method given in ISO 23874. The paper shows how various equations of state can be used and comparing the calculations to experimental measurements (both laboratory measurements of synthetic naturals gases and field measurements) - where applicable; indicating pitfalls and solutions. The paper also shows how the recent GERG-2008 (ISO 20765-2) equation can be used to calculate hydrocarbon dew points of natural gas.

Importance of PVT and Thermodynamic Models for Multiphase Flow Metering Applications Victor Ruehle, Xiaohong Zhang & Alessandro Speranza, KBC Advanced Technologies, Richard Streeton & Ingve Morten Skjldal, FMC Technologies Multiphase flow meters (MPFM) today play essential roles in production optimization/management and fiscal allocation both offshore and onshore. MPFM technology has matured considerably since they were introduced in the 1990s and the industry experience has brought increased confidence in their accuracy and reliability. When correctly applied the advanced capabilities of MFPM can generate huge financial savings for operators in operational efficiencies - but most importantly in increasing overall reservoir recovery factors. MPFM need to be configured with accurate physical property (PVT) and thermodynamic models as well as the transport properties of the individual gas oil and water phases in order to accurately deduce the volumetric flow rates using on a variety of sensor measurements at operational conditions. This paper aims to highlight the unique capabilities offered by the Multiflash software when integrated into the flow computer of the MPM multiphase and wet gas flow meter manufactured by FMC Technologies. The paper will elaborate on the ability to update fluid models dynamically using the MPM in-situ verification functionality and on how very high accuracy gas phase properties can be provided which are essential for metering flows with high gas volume fractions.
