Product yield

Everyone, when calculating the yield of tar processed products, should we calculate the amount of anhydrous tar or the qualified tar amount of 4%.
The national standard is that water is less than 4%. There should be specific laboratory data. It should not be calculated as anhydrous. Can someone please explain?
It is not contradictory to calculate that tar production does not contain water, but tar actually contains water. When calculating the coke output of a coke oven, the calculated output does not contain water, but in fact the moisture content of coke is usually around 4%. Calculated without water, the calculation results are more comparable.
It is calculated based on anhydrous tar, and the water needs to be deducted when calculating.
When calculating tar production in a coking plant, 4% moisture is used. When calculating productivity in a tar processing plant, anhydrous tar is used.
