The most widely used application is natural gas drying to prevent water freeze up in cryogenic process trains.
4A-DG molecular sieve in 1/16 inch pellets, 1/8 inch pellets and 1/8 inch TRISIV form are used in most of natural gas dryers.
4A-LNG molecular sieves can remove CO2, H2S and low molecular weight mercaptans from natural gas.
4A-LNG molecular sieves can remove water and CO2 from natural gas.
TOP’s RK-29 molecular sieves can remove H2S and low molecular weight mercaptans from propane, and 13X molecular sieve to remove heavy molecular weight mercaptans from butane.
