Technologies

We are molecular separations specialists focused on process intensification and sustainability. We have a wide range of commercially proven technologies and more are under development that are built around proprietary materials.

Current available commercial technologies:

Membrane Hybrid with each other and with existing unit operations such as Distillation, Adsorption, Salting-Out, Crystallization and Extraction

Zeolites Evolution – Structure 

Zeolites are crystalline, microporous, hydrated aluminosilicates containing alkali or alkaline – earth metals mainly, sodium (Na), potassium (K), magnesium (Mg), and calcium (Ca)

M : Cation viz. Na, K, Mg, Ca etc.

n  : Valence

w: Number of water molecules

y/x : Si/Al ratio

The commercial zeolite that we offer is LTA type or called A Type

Separation Fundamentals -ZeoSep LTA

Structure of Zeolite LTA-type

Nature: Hydrophilic

Pore Size: 0.4 nm

Separation Fundamentals – Cross Section 

Separation Fundamentals – ZeoSep LTA

  • Zeolite “A” is the most hydrophilic Zeolite (due to the Si/Al ratio of 1.0)

  • Pore size of Zeolite A ~ 0.4 nm (4 A)

High Flux and High Selectivity for

Organics Dehydration Applications

Separation Fundamentals – ZeoSep

The separation occurs using the Adsorption – Diffusion Mechanism.
