Abstract
A (V)PSA unit for purifying a gas stream by adsorption is provided. The (V)PSA unit comprises, arranged successively in the direction of flow of the feed gas stream, a rotary-structured adsorbent wheel configured so as to drive the gas stream therethrough in an axial manner and allowing the feed gas to dry to a level corresponding to a dew point below −30 C., and an adsorber with a centripetal radial configuration, comprising a bed of particulate adsorbent.
Claims13
A (V)PSA-type adsorption unit for purifying a gas stream, successively comprising, in the flow direction of the feed gas stream:
- a rotary structured adsorbent wheel configured to drive the gas stream therethrough in an axial manner and configured to dry the feed gas to a level corresponding to a dew point below −30° C., the adsorbent wheel comprising at least one zone dedicated to adsorption and at least one zone dedicated to regeneration;
- and
- an adsorber of centripetal radial configuration comprising a bed of particulate adsorbent.
