PROCESS AND EQUIPMENT FOR TREATING REFINARY GASES CONTAINING HYDROGEN SULPHIDE |
摘要 |
A process for the abatement of hydrogen sulphide in refinery gases by means of a liquid-ring compressor (10) uses, as service liquid, an aqueous solution of amines already available in the refinery itself. The process also comprises a stage of washing of the gas discharged by the compressor, by means of a column (20) mounted on a three-phase separator supplied with a regenerated solution of amines. The treatment in the liquid-ring compressor enables an effective abatement of the amount of hydrogen sulphide to be achieved, which can be further improved by washing using a regenerated amine solution supplied to the column set above the liquid/gas separator (18) downstream of the compressor.
