Abstract (en)
[origin: WO2009158064A2] The present invention provides for removal of carbon dioxide and hydrogen sulfide from a synthesis gas stream. A partial pumparound is provided to cool a portion of the solvent leaving the bottom of the carbon dioxide absorber. This allows for a reduction in the solvent circulation rate and associated equipment sizes.
