IMPROVED CORROSION CONTROL IN ACID GAS REMOVAL EQUIPMENT BY THE SITU GENERATION OF POLYSULFIDE IONS |
摘要 |
A method for the reduction of corrosion in a treatment unit acid used for separating hydrogen sulfide from and acid gas stream using an alkaline absoiption solution. Ions comprising the S2- and/or HS- ions formed by the absorption of the hydrogen sulfide in the absorbent solution are subjected to in situ electrochemical oxidization to form polysuifide ions which form a protective coating on the surfaces of the unit. |
