Abstract

The present invention relates to a process for the dehydration of a gas, particularly of a gas where the gas values should all be substantially recovered as dehydrated gas. The process uses membrane dryers and provides a sweep gas for each of the dryers The sweep gas is substantially recovered and used again as a sweep gas. The process is economical and can process large quantities of gas.
