What do I need to Create Renewable Natural Gas from Biogas?
…an introduction
BIOGAS requires upgrading to be used as CNG or LNG Vehicle Fuel
• Pressure:• Common: 2 – 8 inches of water column• Municipal applications: up to 15 inches
•Major Constituents:
Raw Biogas Characteristics
Renewable Natural Gas Interchangeability
• Upgraded biogas can be interchangeable with natural gas
Selected standard requirements for grid injection or for utilization as vehicle fuel.

How Does an Upgrading Unit Work?
A Simple Concept
• Biogas is primarily methane (CH4) and carbon dioxide (CO2)
• Water under pressure can be used to separate these two gases through their different solubility in H2O. This happens in the Greenlane Scrubbing Tower.
Water Regeneration• The Greenlane systems recycle water! Only a small amount of water is added compared to the recirculation rates. This make-up water helps keep the system clean, with a similar amount of water blown-down.
•Water from the scrubber is sent to a Flashing Tower to partially depressurize, so the small amount of absorbed methane can be removed from the water, enhancing methane recovery
• The water is then sent to the Stripping Tower that removes the gases absorbed in the water
• Once stripped, the water is re-used to clean more Biogas!
How Does the Greenlane Water Scrubber work?
• The raw biogas is compressed, then fed to a ‘scrubbing’ tower where it is contacted with water. CO2, H2S, siloxanes and other trace contaminants are preferentially absorbed by the water.
• Absorbed methane is ‘flashed’ off, in a tower at a lower pressure and recovered by returning it to the start of the process.
• Product gas is further purified by a drier, before being analyzed and delivered to the customer.
Greenlane Water Scrubbing Technology in Focus
Water used as the scrubbing agent
Water scrubbing process upgrades raw biogas to vehicle fuel or pipeline standards efficiently, and with less impact on the environment Biomethane quality exceeds recognized international vehicle fuel standards and natural gas quality specifications.
Full Automation
The entire plant is controlled by a PLC that monitors all parameters required for safe and productive operation Hydrogen Sulphide
Greenlane’s innovative, patented “polishing” process is proven to reduce biomethane H2S carryover to typically less than 1 ppm in the biomethane.
Track Record
Greenlane has been building water scrubbing systems for over 20 Years, with over 80 Systems Worldwide.
High Availability Biomethane Systems
Greenlane® Totara Compression Skid
• Greenlane biomethane plants have the highest availability in the market.
• Twenty years of experience and seven generations of design have translated into a set of standard systems with no surprises.
• Issues around biogas liquids handling, contaminant fouling, biogas composition variations, etc., have been solved.
• Repeating proven designs with reliable components controlled by verified software is our recipe for eliminating operational risk.
• Remote monitoring and management ensure plants perform as expected.

Kanuka Rimu Matai Totara
Rimu offers over twice the capacity of Kanuka, with nominal flow of 800 Nm3/hr.
This particular size is the most proven in upgrading. It is a simple design withexcellent reliability and high uptime availability (95% - 98%).
Kanuka combines simplicity, low cost and compactness to make it a sharply competitive proposition up to 300 Nm3/hr.
Housed in a 20ft container and offering the patent pending and disruptive Water Flooded Screw technology, enables simplification of the biogas upgrading process and significant cost savings.
Matai fits the requirement for mid-range capacity up to 1200 Nm3/hr while retaining the same benefits of efficiency and economy of scale as the larger Totara plants.
The units are offered in purpose built enclosures to provide an elegant and highly maintainable solution.
Totara & Totara+ are the largest models currently offered with capacities of 2000 & 2500 Nm3/hr respectively. Greenlane have supplied or have orders for 32 of these plants around the world.
Totara’s efficiency and methane yield are the best available. Like the Matai, the Totara units are generally supplied in purpose built enclosures, with the majority of Totara+ supplied non-containerised in client supplied building.

How do I Know if I Have a Project?
… determining project feasibility
Assessing Feasibility
Vehicle Fuel vs Other Uses
© 2010 Canada Gas Association
Vehicle Fuel vs Other Uses
• Higher efficiency = More gas = More revenue. ($)
• Most farms have several vehicles (Utility vehicles, milk trucks, pick-up trucks) for essential farm operations with Diesel being their largest expense.
• Low cost of electricity leads to low PPA’s. Making CHP not viable. Vehicle Fuel replacement makes a Project viable again.
• It is a proven technology. CNG vehicles have existed for a long time.
• The market is here. Infrastructure investments in Natural Gas are being made all throughout the United States. Fueling stations are being added almost everywhere.
Assessing Feasibility for CNG
In order to do a feasibility study we must analyze the following variables:
CNG (Diesel) price: 7.41 DGE per MMBTU. 1 gallon of diesel contains in average 0.135 MMBTUs. The US Energy Information Administration (EIA) posts an diesel price forecast data per region. Pick the low oil price case as it is the most conservative.
Assessing Feasibility for CNG
You also must reduce from the revenue streams the operational costs associated with converting to vehicle fuel:
• Heating Costs of Digester• Biogas Upgrading Costs• CNG Compression Costs• Additional Labor• Utility consumption of the various pieces of equipment.
Capital Expense, Financial Costs and Development and Permitting Expenses must also be considered when determining feasibility.
After modeling both scenarios (High and Low Diesel pricing). If the low oil price Diesel case gives back an IRR of 18-25% the project is feasible.
