Abstract
A gas separation apparatus and process has a first pressure swing adsorption (PSA) unit ( ) receiving feed gas ( ), which comprises a first and a second component. First PSA unit ( ) produces first product gas ( ) pre-dominantly containing the first component, and first off gas ( ) containing at least some of the first component and second component. Compressor ( ) is coupled to first PSA unit ( ) to compress first off gas ( ) to form compressed off gas ( ), which is passed downstream to absorber unit ( ), which employs a solvent to remove at least part of the second component from compressed off gas ( ), forming an enriched compressed off gas ( B). Second PSA unit ( ) receives enriched compressed off gas ( B) and produces second product gas ( ) which predominantly contains the first component and a second off gas that is sent to waste or reformer burner ( ).
