Protein Purification ot Produce Edible Soybean Protein Abstract This project recommends a design for a soy processing facility to produce soy protein concentrates (SPC), soy oil and soy molasses from dehulled soybeans. Utilities were minimized, wherever possible by evaluating whether streams within the system had the capacity to heat or cool other processes. The plant has a production capacity of 170 MM lb soy protein concentrate/year and will be located in Decatur, IL. The proposed design also yields 114 MM lb soy oil/year and 62 MM lb soy molasses/year. The SPC, soy oil and soy molasses have less than 2 PPM residual solvent concentrations and comply with FDA regulations. The plant is running with an uptime of 80% and economic analysis shows an estimated IRR of 41% with an ROI of 59%.

Gopalratnam, Enclosed you will find a proposed design for the soybean processing facility, specified in the problem statement provided by Dr. Gopalratnam. The proposed plant is for the industrial production of 170 MM lb/year of food-grade soy protein concentrate (163 MM lb/year on a dry basis), as well as 114 MM lb/yr of soy molasses, and 62 MM lb/yr unrefined soybean oil from dehulled soybeans in Decatur, Illinois. The process implements both hexane solvent extraction technology and ethanol solvent extraction technology. Dehulled soybeans are processed via conditioning and grinding. The soybeans are then taken through hexane extraction and ethanol extraction as well as desolventization. Production was assumed at 80% uptime, and rigorous profitability analysis was performed to determine plant feasibility. The proposed plant is found to be economically feasible given a permanent investment of the plant of $170 MM, with an expected NPV of $395 MM by 2038. It has an estimated IRR of 41% and ROI of 58%. The following report contains a detailed process design and profitability analysis of the proposed plant, including rationale for key design decisions. It is recommended to pursue plant production using the outlined process design, but continue to research into other potential solvent extraction methods.
