Simulation Modeling (SuperPro Designer) • - required it before setting-up a plant • - scale-up of plant • - reaction synthesis and analysis • - reactor volume • - functionality • - environmental impact evaluation • - waste treatment system • - economic analysis Conclusion Plant Design
Conclusion (con’t) • Limitations • - thermodynamic data of some reagents, reactions and associated products • - patent and synthesis pathway • - synthesis chemist • - competent in SuperPro Designer • - waste recycle and minimization • - cost-effectiveness analysis Plant Design (con’t)
Conclusion (con’t) • Achievement • - establish a bulk scale infrastructure of protease inhibitor production plant • - establish a process synthesis and analysis of reaction 1 and waste treatment system • - exploited of computer simulation modeling • - logical scheme for real world situation Plant Design (con’t)
Conclusion (con’t) • Environmental regulations are the important issues which the plant have to deal with and follow • Plant should be designed at the best standard, and more stringent to protect the environment • Pollution control system must be designed, constructed and installed • Environmental management have to set-up for ensuring the environmental performance and continual improvement Pollution Control strategies
