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.
