Abstract
A gas purification process for treating a gas stream includes supplying the gas stream to at least one membrane unit to produce a permeate stream and a retentate stream. The retentate stream contains a lower concentration of at least one of water, hydrogen sulfide, or carbon dioxide as compared to the gas stream. The retentate stream is supplied to a molecular sieve unit to remove hydrogen sulfide to produce a treated gas product stream.
