The Mass Balance Approach. The chemical industry uses a small number of raw materials to create tens of thousands of different products. The lion's share of chemical production starts in the steam cracker, where steam is used to split or "crack" naphtha, a long-chain hydrocarbon, into smaller molecules.

i.e. total mass of input = total mass of output. A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes. 4.2. The General Balance Equation

In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass. However, in a wet process water is added to the raw mix to form slurry and then is transported to the kiln [11]. Raw meal or blended raw materials are fed into the upper end of the pre-heater tower and then passed through the end of the rotary Kiln.
