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 sodium hydroxide solution, reacting the effluent liquid with an acidic reagent, 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 reacting the resulting effluent liquid, 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.
