Abstract:
A method for the production of a gas stream containing a product gas comprising:a) subjecting a stream of a reactant gas to a product gas producing process to form a reactant gas and product gas containing stream;b) adsorbing said product gas from said reactant gas and product gas containing stream in a bed of adsorbent so as to produce a reactant gas containing and product gas depleted stream;c) displacing reactant gas from said bed by passing through the bed a stream of purge gas;d) recycling said reactant gas containing and product gas depleted stream and said displaced reactant gas into the product gas producing process;e) removing the product gas from said bed in a flow of said purge gas to produce said gas stream containing a product gas, thereby regenerating said adsorbent for product gas adsorption; andrepeating steps (b) to (e) in a cyclic manner.
