Abstract

1375728 Drying gases BAYER AG 8 Nov 1971 [11 Nov 1970] 51780/71 Heading B1L A two stage process for drying a gas mixture and subsequently separating one component comprises passing the gas through a first zone to absorb moisture and through a second zone to absorb the component(s). Under reduced pressure during regeneration the adsorbed component is used to dry the first zone. When the process is repeated the pressure in the first zone is built up prior to build up in the second zone.
