CONTROL OF CARBONYL SULFIDE WITH SODIUM BOROHYDRIDE IN CAUSTIC TOWERS FOR PETROLEUM/PETROCHEMICAL PROCESSES |
| 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. |

1. A method for removing carbonyl sulfide from a process stream containing it, the method comprising contacting the process stream with an amount of sodium borohydride effective to react with the carbonyl sulfide to form at least one reaction product, where the at least one reaction product may be removed from the process stream by a process selected from the group consisting of:
washing away the at least one reaction product with a basic compound; trapping the at least one reaction product, where the at least one reaction product has a higher boiling point than carbonyl sulfide; and combinations thereof. |
