摘要
Sodium borohydride (NaBH4) may be used to removing carbonyl sulfide (COS) from a process stream containing it. The method involves contacting the process stream with an amount of effective of NaBH4 to react with the COS to form reaction products that may be removed by a process of washing away the reaction product by an aqueous basic compound and/or the reaction product having a higher boiling point than carbonyl sulfide which permits trapping the reaction product, such as in a caustic tower.
