Question

What is the water quantity in the coke at the end of the coking process?
(A) 10%
(B) 20%
(C) 0%
(D) None of these

Answer 1

Hint :To answer this question we need to understand the process of cooking. This is the process of formation of pure coke. Metallurgical coke is an important raw material for blast furnace pig iron production. Coke is subjected to severe mechanical, thermal, and chemical stresses during this process.

Complete Step By Step Answer:
One of the most useful fossil fuels is coal. It has a wide range of uses, including the generation of heat for homes, the firing of industrial generators, the production of cast iron, and so on. It can also be processed in an industrial setting to produce products such as coke, tar, and coal gas.
Coke is a high-carbon product made by distilling coal in a destructive manner. Coke has such a high carbon content that it is considered an almost pure form of carbon. Coke is a hard, porous solid that is greyish-black in color.
Coke is primarily used as a fuel for stoves, furnaces, and blacksmithing. Because coke produces very little smoke, it is sometimes preferred over coal. In a blast furnace, it's also used to make iron. Steel and a variety of other materials are also made from coke.
The final step in the purification of coke is coking. After this procedure, the percentage of water in coke was practically zero.

Note :
For resid, heavy oil, and tsar sand bitumen processing, a coking process is one of several options. Because heavy sour crudes have significantly higher levels of vacuum resid in the feed, the coking unit (especially the delayed coker) is typically one of the most capacity-constrained.
