Herold contributing writer amsterdam the netherlands.
Molecular sieve technology is widely used for the simultaneous removal of water and mercaptans from both gas and liquid feed streams.
As a brief overview on molecular sieve dryer.
In addition to these design guidelines there are additional considerations in liquid dryer design.
A molecular sieve works by adsorbing gas or liquid molecules that are smaller than the effective diameter of its pores while excluding those molecules that are larger than the openings.
Optimal design and operation of molecular sieve gas dehydration units part 1.
These pore diameters are similar in size to small molecules and thus large molecules cannot enter or be adsorbed while smaller molecules can as a mixture of molecules migrate through the stationary bed of porous semi solid substance referred to as a sieve or matrix the components of highest molecular weight.
