TEHRAN Feb 28(Shana)–Iran has managed to produce a much-needed solvent used in sour gas sweetening process, director of research and technology at National Iranian Gas Company said.
Saeed Pakseresht said Iranian refineries will soon see their sweetening solvent consumption rise from the current 5,300 tons to 13,000 tons a year.
“Indigenization of this solvent is among projects which started five years ago,” he said.
While most of the sour gas is sweetened with regenerative solvents, for slightly sour gas, it may be more economical to use scavenger solvents or solid agents. In such processes, the compound reacts chemically with the H2S and is consumed in the sweetening process, requiring the sweetening agent to be periodically replaced.
