ABSTRACT

Reactive extraction is a promising technique for the recovery of organic acids from aqueous

streams. Succinic acid, is a white, odorless solid dicarboxylic acid, and is a precursor for

some specialized polyesters. Present paper presents an optimization study of reactive

extraction of succinic acid equilibrium studies from aqueous solutions using Tri-n-octylamine

in 1-Decanol using response surface methodology including reaction kinetics in a stirred

cell. Extraction efficiency (𝑌), a response function was optimized using three process

parameters: initial succinic acid concentration, tri-n-octylamine composition, and

temperature(𝑇). Response surface methodology in conjunction with central composite design

consisting of twenty experimental runs was statically employed for the reactive extraction of

succinic acid. A statistical second order polynomial quadratic model predicted an extraction

efficiency of 93.75% with optimum values of parameters being: 0.2 kmol m-3

acid

concentration, tri-n-octylamine composition 33 (% v/v), at 305.5 K temperature. The

extraction efficiency obtained was 91% at the optimal conditions. The kinetic studies were

carried out to analyze the process. Interfacial area correlation was derived based on the

droplet radius. The mass transfer coefficients of succinic acid, tri-n-octylamaine, and 1:1

acid-amine complex in 1-decanol were determined using water/acetic acid/kerosene system.

Based on the Hatta number, the reaction regime found to be instantaneous reaction regime

occurring in the film.

Keywords: central composite design, equilibrium studies, kinetic studies, optimization,

INTRODUCTION

Succinic acid and its derivatives have vast

usage in polymers, foods, pharmaceuticals,

and cosmetics. At present, the commercial

succinic acid is nearly all of produced by

the chemical process from maleic

anhydride derived from petroleum; which

limits the use of succinic acid for a huge

range of applications due to the high

conversion cost. Anaerobiospirillum

succiniciproducens,[1–5]

Actinobacillus

succinogenes[6–9]

and Mannheimia

succiniciproducens[10]

(isolated from

bovine rumen), which were discovered as

facultative anaerobic bacteria, are newly

considered as effective succinic acid

producers due to the high demand for

succinic acid production.[11,12]

Reactive extraction with specific

extractant giving higher distribution

coefficient has been suggested as a

promising technique for the recovery of

carboxylic acids. Separation of acids from

their aqueous

Novel Ionic Liquids Supported Membranes: A Review

Tejas T. Shetiye, Shamali S. Chavan, Swapnil A. Dharaskar* Department of Chemical Engineering, Dr. D. Y. Patil Institute of Engineering, Management, and Research,

Akurdi, Pune (M.S), India

ABSTRACT

In this work, a supported ionic liquid membrane (SILM) can be prepared by impregnating

different types of polymers with suitable novel phosphonium-based ionic liquids (ILs). ILs

have reached an enormous interest as CO2 solvents and other engineering applications due

to their unique properties such as negligible vapour pressure and selectivity, making them

very attractive in order to obtain stable supported liquid membranes. This work can appraise

the preparation and use of a new class of supported liquid membranes. ILs are compounds

that typically contain organic cations and inorganic anions with unique properties. These ILs

can be synthesized by the reaction of phosphonium-based salts with different hydrogen bond

donors. Phosphonium cations based ILs are a readily available family of ILs that in some

applications after superior properties as compare to Nitrogen cation based ILs. These are

used as Extraction solvents, Chemical synthesis solvents, electrolytes in batteries and in

super capacitor-anion combinations that are available commercially. Here, we provide an

overview of the properties of these interesting materials and their diverse applications. An

evaluation of the membrane stability was carried out for stable SILMs can be experimentally

determined.

Keywords: CO2 separation, ionic liquids, phosphonium-based ILs, supported ILs membrane

INTRODUCTION

Ionic Liquids (ILs) are having different

unique properties like, low melting

temperature (<100°C), wide liquid phase

range, high thermal stability, non-

flammability, and very low vapour

pressure and ILs compounds typically

contain organic cations and inorganic

anions.[1]

Due to the remarkable increase

in research related to the use of ILs as

potential replacements for organic solvents

in chemical processes.[2]

The rising interest

about ILs in regards to Green Chemistry

and Engineering has largely been a result

of the fact that they have no measurable

vapour pressure, thus they do not release

volatile organic compounds (VOCs).[3]

ILs

also have a diversity of potential

applications.[4]

Now days, ILs has been predictable as an

alternative to prevailing solvents and ILs

themselves. They are a Grouping of a salt

and a hydrogen-bond donor (HBD), in

which a new compound is formed, usually

having much lower melting temperature

than the components of the combination.

They can be easily prepared in high purity

at low cost, and their components are

biodegradable and possess low toxicity, So

that they are more advantageous. Industrial

applications of phosphonium-based ILs are

very favourable and we can find out

various chemical engineering applications

with SILMs.

Carbon dioxide (CO2) absorption is a

significant separation process where

efforts have to be applied in order to

The Performance of Microbial Lipase Immobilized onto Ion

Exchange Resins and onto the Natural Zeolite Clinoptilolite

Laurence Weatherley*, Akash Anand Department of Chemical and Petroleum Engineering, Learned Hall, The University of Kansas, KS, USA

ABSTRACT

The paper describes a study into the performance of a microbial lipase immobilized on to

four different ion exchangers. Lipase from the yeast Candida rugosa was immobilized onto

the anionic ion exchange resins Dowex MWA-1, Purolite A109, and Amberlite IR45. The

performance of the immobilized lipase in each case was evaluated by measuring the

immobilization efficiency and by following the reaction kinetics of hydrolysis of a tri-

glyceride ester to free fatty acid and glycerol. The immobilization efficiency is a measure of

the enzyme activity in the immobilized state relative to the free enzyme. The performance of

the three synthetic anionic ion exchangers was compared with that of the naturally occurring

zeolitic cationic exchanger – clinoptilolite, which was similarly evaluated as a lipase support.

The potential improvement of immobilization using the technique of pre-cross-linkage of the

lipase using a glutaraldehyde crosslinking agent was also studied. The final part of the study

focused on the potential enhancement of reaction performance through the addition of pure

form cationic and anionic ion exchange resin to the reaction mixture together with the

immobilized enzyme as a means of in-situ removal of free fatty acid product. In all cases the

specific enzyme activity for the immobilized lipase was significantly lower compared with the

activity in free solution. The Purolite A109 displayed the highest value of immobilization

efficiency but only by a small margin compared with the Dowex MWA-1, and the Amberlite

IR45. The clinoptilolite showed immobilization efficiency 50% lower than that of the

synthetic ion exchangers. The application of glutaraldehyde cross-linkage during the

immobilization protocol in the cases of the Dowex MWA-1 and the Purolite A109 resulted in

increases in total protein uptake of 14.5 and 4.1%, respectively. The significant increase in

total protein uptake in the case of the Dowex MWA-1 was not reflected in any significant

enhancement of reaction kinetics. The reaction kinetics exhibited by the lipase immobilized

on the anionic Purolite A109 resin, when mixed with cationic ion exchange resin in the

sodium form during the reaction showed substantial enhancement. This observation suggests

removal of fatty acid product through ion exchange uptake of H+ ions.

INTRODUCTION

Enzymes are naturally occurring

sustainable catalysts, which function

effectively at close to ambient conditions

of temperature and pressure. Therefore,

they offer scope for more environmentally

friendly and more cost-effective chemical

manufacture. The application of many

heterogeneous catalysts at industrial scale

requires mounting the active catalyst agent

on to a stable solid support. This is

essential for effective catalyst re-use, for

the control of mixing, and to allow

efficient contact of the reactant rich gas or

Numerical Analysis of Flow Characterization in a Continuous

Crystallizer

A. Thimmaiah, L. Falleiro, A. Naval, A. Ambekar, B. Ashraf Ali* Department of Chemical Engineering, National Institute of Technology Karnataka, Mangalore, India

ABSTRACT

In this work, hydrodynamics in a draft tube continuous crystallizer is analyzed

computationally through Ansys CFD in terms of crystallization phenomena. Hindrance to

fluid mixing and particle suspension due to vortexing can be overcome by providing baffles.

A draft tube ensures that it directs the flow in the vertical direction ensuring good axial

blending. Here, CFD simulations are performed using multiple reference frame (MRF) with

sliding mesh approach in transient condition for a flow time of 5s. The flow fields and liquid

circulation patterns were modelled using the standard k-ε turbulence model. The flow-field in

the continuous crystallizer is quantified by calculating time averaged velocity profiles along

the horizontal line and by analyzing the temporal variation of liquid velocity at a point for

various flow rates. Further, turbulence in such crystallizer is analyzed for various flow rates.

The liquid circulation in such a continuous crystallizer is calculated for various flow rates to

find an optimal flow rate at which the continuous crystallizer is to be operated, hence to

improve overall performance of the crystallizer; as it depends both on the mean flow field

and on the associated turbulence characteristics.

INTRODUCTION

Crystallization is the formation of solid

particles within a homogenous phase.

Solid particles can be formed from either

vapor phase or liquid phase through

crystallization [1]. Crystals formed during

crystallization from an impure solution are

itself pure and suitable for packing and

storing. Above 80% substances that are

used in pharmaceuticals, fine chemicals,

agrochemicals, food and cosmetics are

either isolated or formulated in their solid

form. The primary goal of crystallization is

to generate pure particles with the set size

and shape, which eases downstream

operations. Crystallization is complex as it

involves the coupling of several individual

phenomena. The hydrodynamics of non-

ideal mixing coupled with the kinetics of

nucleation and growth affect the final

crystal size distribution. The driving force

for crystallization from solution is

supersaturation. Based on the dependence

of solute solubility on a number of factors,

four methods have been classified for

generating supersaturation- temperature

reduction, evaporating the solvent,

changing the solvent composition (salting)

and chemical reaction (precipitation).

If the solute concentration exceeds the

equilibrium (saturated) solute

concentration at a fixed temperature, then

the solution is said to be a supersaturated

solution. Formation of crystal is generally

considered to be a two-step process. First

is the formation of nuclei known as

nucleation and second is the growth of

Methods of Separation: A Guide to Beginners

Shalu Singh*, Aruna Singh Department of Engineering and Technology, Indira Gandhi National Open University, New Delhi, India

ABSTRACT

Learning different separation methods is important in chemical and biochemical world.

Different techniques are known that helps to separate complex mixtures of substances.

Herewith, we provide a brief overview of these methods which can be helpful for the students

that are in the beginning of their learning stage of chemical separation methods and

techniques.

Keywords: analyte, distillation, filtration, membrane, separation

BACKGROUND

Several techniques are available to

separate mixture of two or more

substances. It is required that these

substances should differ in at least one of

their physical or chemical characteristics.

A mixture of substances can be separated

based on their size, density, physical or

chemical state, complex formation, etc.

Herewith, we provide an overview of

such separation techniques that exploit

the physical and/or chemical properties

of the analyte or the interferent in a

mixture [1].

SEPARATION METHODS BASED

ON SIZE

Size is the simplest physical

characteristic that can be exploited as a

separation method. Usually, a porous

medium of specific pore size is used

through which the mixture of analyte and

interferent is made to pass. Only one of

the two substances can pass through the

medium while the other is left on the

porous medium. Techniques that work on

this principle include filtration, dialysis

and size-exclusion.

FILTRATION

This is the simplest and the most common

separation method based on size. A

membrane or filter of particular pore size

is used that retains the interferent from a

mixture of dissolved analytes. The

substance retained on the filter is termed

the retentate while the other that passes

through the membrane is referred as the

filtrate. Different membrane filters having

varying pore size are easily available for

these purposes.

DIALYSIS

This separation method is based on the

difference in the concentrations of the

particular species to be separated on two

sides of the separating membrane. In this,

the mixture or the sample is injected into

the dialysis membrane, usually made up of

cellulose that is tightly sealed in a gasket.

The whole apparatus is kept in a large unit

and filled with liquid whose composition

is different from the sample. The

concentration gradient of the species to be

separated on the two sides of the liquid

solution acts as the driving force for its

diffusion across the separating membrane.

This method is used to separate enzymes,

proteins and hormones. Dialysis is also
