PROCESS SIMULATION AND OPTIMIZATION OF CYCLOHEXANE MANUFACTURING PLANT USING UniSim AND HINT

Chinju P T and Syama S

The Energy crisis and Low production rate are the important parameters in industrial operations. In this point, the simulation and optimisation of plant is highly desirable. This study shows the simulation of cyclohexane manufacturing plant. Cyclohexane is mainly used as an intermediate chemical compound for the production of adipic acid. It prepared by the hydrogenation reaction of benzene at elevated temperature and pressure. Honeywell’s UniSim software R470 was used for the simulation and optimization processes and the fluid package employed was PRSV. Heat exchanger network design for pinch method has been carried out using HINT educational software. Pinch technology is used for Energy and Cost optimisation. This study reveals with all the stages of the design, which include cost targeting, area targeting, utility selection and heat exchanger network designing (HEN). The results of the base and optimized cases were compared and analysed. It has been shown that the developed UniSim model of this work can be used to represent, simulate and optimize a cyclohexane stabilization system successfully. This simulation helps engineers to create steady-state plant design, performance monitoring and troubleshooting.
