The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. Σm R = Σm P + Σm W + Σm S (where Σ (sigma) denotes the sum of all terms). Σm R = Σm R1 + Σm R2 + Σm R3 = Total Raw Materials Σm P = Σm p1 + Σm P2 + Σm P3 ...

4. All material balance calculations in this chapter are made on steady state processes in which the accumulation term is zero. However, material balance on a batch process can be made over a residence time and on the basis of one batch ( integral balance). Figure 6: Initial conditions for an open unsteady state system with accumulation.

Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.

The mass balance approach. Many BASF value chains start in syngas plants or steam crackers, where fossil resources, mostly natural gas and naphtha, are converted into hydrogen and carbon monoxide or important basic chemicals such as ethylene and propylene.These are used to create thousands of products in the BASF Verbund.

Milk fat. Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum, Figure 2.15. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3 – 4 µm and there are some 10 10 globules per ml.

The partition of P in the slag to P in the bath ranges usually from 5 to 15. Generally P is reduced by 20 % to 50 % in the EAF. Sulphur is removed mainly as a sulphide dissolved in the slag. S partition between the slag and metal is dependent on slag chemistry and is favored at low steel oxidation levels.
