Raw material for the production of proteins
- 11 Downloads
The choice of a paraffin-containing petroleum raw material for the production of feed protein is governed by the cost of the n-paraffins contained in the petroleum product and the costs involved in obtaining products of the required quality from these raw materials.
In the current five-year period, for the production of feed yeast, the starting material will consist of purified liquid waxes in the form of a light fraction with a boiling range of 280–320°C, obtained by distilling a wax fraction that has been recovered and purified in existing units.
The utilization of liquid waxes differing in degree of purity for the production of feed yeast will be profitable in all cases; however, as shown by preliminary calculations, it will be less favorable than the use of petroleum distillates if the cost of commercial waxes exceeds the cost of the n-paraffinic hydrocarbons in the petroleum distillates plus the costs for extractive treatment of the biomass grown on this material.
Petroleum distillates are promising raw material for the development of large-scale production of feed protein.
