PROCESS FOR CAPTURING SULFUR DIOXIDE FROM A GAS STREAM. |
摘要 |
A process for removing sulfur dioxide from a feed gas stream, which comprises (i) contacting the feed gas stream with an aqueous lean absorbing medium comprising a chemical solvent comprising a regenerable absorbent, a physical solvent, and one or more heat stable salts. The regenerable absorbent is an amine. The ratio of the wt% of the physical solvent over that of the regenerable absorbent is 0.5 to 2.5. The ratio of the wt% of heat stable salts over that of the regenerable absorbent is 0.29 to 0.37. The pH of the lean absorbing medium is 6 or less. With the process SO2 can be selectively removed. When the absorbing medium is stripped, a reduced amount of energy is required as compared to known processes. |
