METHOD FOR USING NATURAL GAS FUEL TO IMPROVE PERFORMANCE OF PRESSURE SWING ADSORPTION HYDROGEN UNIT IN AN INTEGRATED FACILITY

摘要

A process is disclosed for increasing hydrogen recovery in an integrated refinery and petrochemical complex in which natural gas is used as a co-purge gas in a pressure swing adsorption unit. This natural gas is recovered in tail gas from the pressure swing adsorption unit. This process is useful for refinery off-gas and partial oxidation feeds.
