High-temperature carbonization of one ton of dry coal yields approximately ______________ Nm3 of coke oven gas?
Show answer Hide answer
Answer: B. 300
Explanation
High-temperature carbonization drives off volatile constituents from bituminous coal feedstock. Thermal decomposition of one ton of dry coal releases approximately three hundred normal cubic meters of gas. This volatile fraction is captured and processed industrially as coke oven gas. Coking bituminous coal without air produces solid metallurgical coke and volatile gas byproducts. Normal cubic meters measure gas volume at standard temperature and pressure conditions. Mass balance calculations in chemical engineering track solid, liquid, and gaseous carbonization yields.
Steel plant engineers use gas yield data to design appropriate collection and cleaning systems. Coke oven gas provides a valuable fuel source for heating industrial furnaces across the plant. Understanding byproduct yields helps optimize coking plant economics and operational efficiency. Thirty normal cubic meters represents a severe underestimation of volatile coal breakdown yields. Three thousand normal cubic meters exceeds the physical mass balance limits of coal composition. Thirty thousand normal cubic meters is physically impossible from processing a single ton of coal.
