Process for treating a gas containing hydrogen sulphide and sulphur dioxide, comprising a step for eliminating sulphur by cooling a gaseous effluent |
摘要 |
In a process and apparatus for treating a gas containing hydrogen sulphide and sulphur dioxide, the gas is contacted with an organic solvent (1)for example, a polyalkylene glycol, containing a catalyst for example, an alkaline salt of a week organic acid, in at least one gas-liquid reactor contactor (2) and a gas (20) substantially no longer containing hydrogen sulphide and sulphur dioxide is recovered. The effluent contains sulphur vapor. It is cooled by mixing with a solvent-water mixture (14) or by cooled solvent in a cooling zone (7) to produce a suspension of sulphur crystals in the solvent. The crystallised sulphur is separated from the solvent in a separation zone (30) and the cooled solvent is recycled (13). An effluent (17) which is free of sulphur gas is obtained.
