I would like to ask fellow professionals in the coal chemical industry: how can we calculate the theoretical tar production and theoretical crude benzene production based on the number of times material is taken out of the furnace over a 24-hour period?
It’s very simple – just calculate it based on the tonnage of coke produced
Is the yield of crude benzene calculated per ton of dry coal, and is it approximately 1%, is that how it’s calculated? What does this yield depend on?

In these formulas: V represents the combustible volatile matter in coal; y represents the yield of a particular substance, in % (on a dry-basis coal basis). With the data on coal output over 24 hours, as well as information on the moisture content of the coal fed into the furnace, it is possible to calculate the yield of each substance.
