DEHYDRATION SYSTEM AND DEHYDRATION METHOD

摘要

Provided are a dehydration system and dehydration method, said dehydration system carrying out regeneration of water separation membranes while the system as a whole is in operation and being made such that the number of water separation membranes required is reduced. The dehydration system has at least one water separation membrane unit (10) in operation and is configured such that for the at least one water separation membrane unit (10) in operation, there can be at least one water separation membrane unit (20) not in operation. Heated gas for regeneration is supplied to a flow path (22) for a fluid to be treated with a water separation membrane (21) of the water separation membrane unit (20) not in operation, and in a state in which the dehydration system is in operation, the water separation membrane (21) can be regenerated by the heated gas for regeneration passing through the water separation membrane (21).
