Abstract:

Aspen HYSYS was used for dynamic simulation of powder conveying system among multiple reactors in gas phase polypropylene production process. The pressure-flow solver, event scheduling tool and control manager used in the simulation are described. The curves of powder flow and powder level changing with time are obtained. It provides a reference for the design of blowcase system.

Key words: gas phase polypropylene production process;blowcase system, sequence control;dynamic simulation
