Question

In the Frasch process for the extraction of sulfur, superheated steam is forced down the outermost of the three concentric pipes is:
A. Wash the sulfur clean
B. Remove the impurities
C. Melt the sulfur
D. Dissolve sulfur dioxide

Answer 1

Hint: Frasch process: It is defined as the process in which the extraction of sulfur takes place from underground deposits. This is the only industrial method to recover sulfur from elemental deposits.

Complete step by step answer:
In the Frasch process for the extraction of sulfur, superheated steam is forced down the outermost of the three concentric pipes. Superheated water at temperature ${ 165 }^{ \circ }{ C }$ and at high pressure is infused into the deposit by means of the outermost tube. Sulfur ${ 115 }^{ \circ }{ C }$ melts and streams into the middle tube.
Water pressure alone can't drive the sulfur to the surface because of the molten sulfur’s more density, so hot air is acquainted by means of the innermost tube to froth the sulfur, making it less dense, and pushing it to the surface.
We use superheated steam because the pipes are deep into the ground and when we make it soften or melt, it can come up without any problem and it is then collected in wooden tubes. After that, sulfur can be converted into solid blocks.
So, the correct option is C.

Additional Information:
Properties of Sulphur allowing extraction:
Low melting point of generally ${ 115 }^{ \circ }{ C }$ because of weak dispersion forces (superheated water dissolves this without any problem).
Insoluble in water and doesn't react with it synthetically (permits it to be gathered on a surface).
Inert, non-volatile, and non-poisonous, which means no special safety measures are required to ensure the health of miners.

Note: The possibility to make a mistake is that here superheated water is necessary, normal boiled water is not helpful to melt the sulfur easily.
