Author has introduced the emission standard for SO2 tail gas in sulphur recovery device at home and abroad in China at present time and also the more severe new standard being soon published;has compared the SO2 content situation in tail gas among technologies of three stage Claus, super class/super good Claus and ordinary Claus + hydrogen adding reduction;has indicated the difficult situation that the present recovery technology does not yet meet the new environment standard;has analyzed the method to further increase sulfur recovery rate;has suggested the developmental direction for sulfur recovery technology, which can satisfy the environment standard.
