The Application of Process Simulation Technology in Sinopec Jinan Co.'s PP Unit

The Aspen Plus software is a large general-purpose process simulation system used in production unit design,steady-state simulation and unit optimization.After more than 20 years of improvements and expansion,this software has evolved through more than 10 editions.It is now a recognized standard large process simulation software product and has been applied in industrial production units in China′s refining and petrochemical industry in recent years.Polypropylene models established using process simulation technology can be used in the study of the relationships between polymer properties such as polymer output and density,melt flow rate and isotacticity and various operating conditions so as to optimize the operation of units and raise product output and quality.In addition,the technology can be used to optimize the operation of propylene recovery units to maximize energy savings.Technicians used this simulation software to carry out a sensitivity analysis for some operating parameters of Sinopec Jinan Company′s 10×104t/a polypropylene unit which uses the Spheripol technology.The software helped the company effectively raise output,reduce feedstock consumption and cut propylene emissions and annual economic benefits from the application of the software reached 2.64 million yuan.These achievements suggest that Sinopec Jinan Company′s polypropylene unit process simulation and optimization program was successful.
