frasch process diagram

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 ..

Mining of Sulphur - Frasch Process A Frasch pump consisting of a set of three concentric pipes is sunk deep into the sulphur bed Super heated water at 170 0 C under pressure is pumped in through the outermost pipe Sulphur in the sulphur bed melts due to i..

-static. To change the pressure of a gas, we can move a piston inside the enclosure. The gas near the piston is acted upon by greater force as compared to the gas away from the piston. The pressure of the gas may not be uniform everywhere while the piston is moving. However, we can move the piston ..

For a proper discussion of the three phases of matter, we require a three-dimensional diagram in which P, V and T should be plotted against three mutually perpendicular coordinate axes. This diagram, known as P-V-T diagram, is difficult to draw on paper. Hence, we gene..

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..
