Removal of acidic gases from hydrocarbon streams
Abstract
Abstract AN APPARATUS AND PROCESS FOR SUBSTANTIALLY REDUCING CARBON DIOXIDE AND/OR HYDROGEN SULFIDE LEVELS IN A HYDROCARBON GAS WITH SIMULTANEOUS REGENERATION OF REAGENT MATERIALS ARE DISCLOSED. THE PROCESS CONSISTS OF PASSING THE GAS THROUGH AN AQUEOUS ALKALI METAL HYDROXIDE SOLUTION, REMOVING ANY SEPARATED HYDROCARBONS WHICH CONSIST OF HEAVY HYDROCARBONS, POLYMERIZED HYDROCARBONS AND POTENTIALLY POLYMERIZABLE HYDROCARBONS WHICH RESULT UPON SETTING, REACTING THE AQUEOUS EFFLUENT LIQUID WITH AN ACIDIC REAGENT, SOLVENT WASHING THE EFFLUENT, STRIPPING THE ACIDIC GASES THEREFROM AND SUBJECTING THE RESULTING AQUEOUS SODIUM SULFATE SOLUTION TO AN ELECTROLYTIC PROCESS. THE APPARATUS USED TO CARRY OUT THE PROCESS COMPRISES AN ACIDIC GAS ABSORBING UNIT, MEANS FOR REMOVING THE HYDROCARBON LAYER WHICH RESULTS UPON SETTLING, MEANS FOR REACTING THE RESULTING EFFLUENT AQUEOUS LIQUID, MEANS FOR SOLVENT WASHING THE EFFLUENT, MEANS FOR STRIPPING THE ACIDIC GASES AND AN ELECTROLYTIC CELL TO CONVERT SOLUBLE ALKALI METAL SALTS INTO THE CORRESPONDING ALKALI METAL HYDROXIDE AND ACIDIC REAGENTS.
