Research on Polygeneration System for circular economy in oilfield and petrochemical enterprises(I):System integration and simulation

In this paper a novel circular economic development mode in oilfield and petrochemical enterprises is presented,which is based on the polygeneration system using discarded petroleum coke as feedstock.Four system schemes are proposed and analyzed in details,including integration patterns,merits and drawbacks.The simulation is made by Aspen Plus.Results show that all of the schemes are theoretically and technically feasible and can fulfill the design requirements of products.The simulated data will be an important base for system evaluation and selection in the next step.
