Production of elemental sulphur from boiler flue gas

Production of elemental sulphur from boiler flue gas utilising the Labsorb regenerative SO2 scrubbing system and the RSR technology for flue-gas sources with a high level of SO2, Labsorb may prove to be the more economic alternative. the SRU will not have to generate its own SO2by incinerating H2S. This in turn reduces the combustion
