frasch process

In Louisiana (USA) and Gulf of Mexico large sulphur deposits occur at a depth of about 300-400 metres below the earth's surface. Layers of soft sand, clay and rocks over these sulphur beds make it practically impossible to extract sulphur from the deposits. Hermen Frasch in 1894 devised ..

Sulphur is extracted from underground deposits by pumping superheated steam (-440 K) down the beds to melt the element and then blowing out the molten sulphur with compressed air. This process is known as Frasch process. Sulphur is also recovered from natural gas by fi..
