Gas desulfurization process
Abstract
Abstract A SELF-CONTAINED PROCESS FOR REMOVING ACID GASES, SUCH AS HYDROGEN SULFIDE, FORM INDUSTRIAL GASES BY ABSORPTIONDESORPTION, WHICH ABSORPTION-DESORPTION INCLUDES SUBJECTING THE INDUSTRIAL GASES TO A VACUUM INDUCED BY A STEAMJET PROCESS AND THEREAFTER REACTING THE DESORBED GASES IN A CLAUS PROCESS TO PRODUCE ELEMENTAL SULFUR. THE ACID GAS-CONTAMINATED STEAM CONDENSATE OBTAINED AS A BYPRODUCT FROM THE STEAM-JET VACUUM PROCESS IS DECONTAMINATED IN A SEPARATE CONDENSATE STRUPPER, AND THE ACID GASES REMOVED FROM THE CONDENSATE ARE REINTRODUCED INTO THE MAIN DESORBED ACID GAS STREAM. THE HEAT PRODUCED FROM THE CLAUS PROCESS IS UTILIZED, BY HEAT EXCHANGE. TO PROVIDE HEAT FOR THE DESORBING OF THE ACID GASES AND THE STRIPPING OF THE ACID GAS-CONTAMINATED CONDENSATE.
