CARBON DIOXIDE ABSORBER PARTIAL PUMPAROUND FOR COOLING SEMI-LEAN PHYSICAL SOLVENT

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 associat...

Zusammenfassung:	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. L'invention concerne l'évacuation du dioxyde de carbone et du sulfure d'hydrogène d'un flux gazeux de synthèse. Un pompage partiel permet de refroidir une partie du solvant en laissant le fond de l'absorbeur de dioxyde de carbone, ce qui permet une réduction au niveau du débit de circulation du solvant et des dimensions de l'équipement associé.
