The Mass Balance Approach BASF
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 longchain hydrocarbon, into smaller molecules. These molecules then serve as the building blocks for downstream production. They include, for example, hydrogen ...
