Abstract
A regenerative adsorption gas dryer has a wet gas inlet, first and second drying towers, and a dried gas outlet. The inlet, towers and outlet are arranged such that, in use, a flow of purge gas regenerates an off-stream one of the towers, while a stream of wet gas from the wet gas inlet enters an on-stream one of the towers to exit that tower as a stream of dried gas which then continues to the dried gas outlet. The roles of the off-stream and on-stream towers are reversible. The dryer further has a first check valve for controlling a stream of dried gas between the first drying tower and the dried gas outlet, and a second check valve for controlling a stream of dried gas between the second drying tower and the dried gas outlet.
