The alternative of incorporating a recycle to reprocess unreacted material (in this case the bound gossypol present in the crystallization mother liquor) is the usual approach in traditional process design. This last alternative renders a slightly lower product yield than Process 2 but requires a smaller investment cost, exhibiting the best economic performance.
While the third process adds a new downstream processing line to reprocess the mother liquor. McGraw Hill, New York, NY), which increases product yield. liquor to the hydrolysis first step of the process, following the heuristic of the traditional process design procedure by Douglas (1988. 14, 113) in which the mother liquor from the last crystallization step still contains an appreciable amount of gossypol which is lost as a process residual stream. The first process is the originally proposed by Dowd and Pelitire (2001. Three processes to obtain GAA from the soapstock residue of oil refineries were compared in this work. The process invention procedure is demonstrated exemplary for the manufacture of methyl-ethyl-ketone from 2-butanol. ASPEN PLUSTM, to fulfill design calculations. Furthermore, PROSYN-M provides an interface to common process simulators, e.g. The segment algorithm which is part of the PROSYN-M problem solving strategy controls the generation of continuous single-product flowsheets. The overall manager system PROSYN-M (Process Synthesis Manager) applies a heuristic branch-and-bound-method to administer and evaluate process synthesis alternatives. Three types of systems can be distinguished: Manager systems, so-called specialists and service systems. character of the synthesis problem the concept of cooperating knowledge integrating systems seems to be best-suited to gain promising process flowsheets. It is the intention to present a strategy which copies the industrial procedure of inventing chemical processes.
This paper summarizes the results of our research after approximately 200 years of manpower in the field of process synthesis. The problem of synthesizing total chemical processes requires extensive conceptual experience as well as a huge fund of detailed engineering skills.
