Production of Protein Supplement Part 1 – Pakistan Industrial sector case study

Summary

The aim of the project was to design a process plant for the production of protein supplements. The basis for the production capacity is 2,500 tonnes per year. The method of the production is to be via biosynthesis. The supplements are to be produced from
the base micro-organism Saccharomyces Cerevisiae.

The production is to be carried out in three bioreactors in a fed-batch manner. The reaction is substrate limited. The medium for the substrate is to be sought from the molasses of sugar beet and sugar cane. The reaction is also designed to be carried out
in fully aerobic conditions as well as in a fully sterile environment as to produce a maximum yield.

The plant is to be productive throughout the year for a total of 330 days, with a maximum capacity of 3,000 tonnes per year should circumstances dictate a need for an increase.

Major aspects such as process description, process control and process safety were detailed in the report.  Process control is directly linked to the P&ID drawing, which details the instrumentation and control loops across the whole plant (with particular
attention to the major pieces of equipment)

The overall capital cost of the plant was calculated to be £6.2 million and the yearly profit was calculated to be £5.4 million per annum assuming constant price.

This report concludes that the process would be highly investible and therefore, worthy of further investigation past this preliminary report in order to try optimise the process.
