Activated carbon system cuts foaming and amine losses
Alkanolamines have been successfully used to treat sour gas for removal of H/sub 2/S and CO/sub 2/ for over 30 years. More recently, alkanolamines have also been used to purify flue gas, liquid hydrocarbon streams and process gas streams. Acid gas must be scrubbed because of the lack of heating value of CO/sub 2/, the toxicity of H/sub 2/S and the corrosiveness of CO/sub 2/ and H/sub 2/S in wet gas. During the scrubbing process, other compounds which form degradation products are absorbed by the amine; these degradation products cause fouling of the amine, corrosion and foaming. Southwestern Refining Co., Inc., in Corpus Christi, Texas, installed a diethanolamine (DEA) treatment system to purify sour gas and liquid hydrocarbon streams in 1975. The amine unit was not used until May, 1982, however, because the sulfur content of the gas stream was low until then.
