Steady State Simulation of Plastic Pyrolysis Process using Aspen Hysys V9 Simulator

Abstract

The present study was carrying out the simulation of plastic pyrolysis process modelled for the conversion of petroleum product from plastic wastes such as Poly-Styrene (PS), Poly-Ethylene (PE), Poly-Propylene (PP) and Poly-Styrene (PS) with the aid of Aspen Hysys V9 simulator. Aspen Hysys simulator was used to develop the steady state model and to simulate the pyrolysis process with the above mentioned plastic wastes. Peng-Robinson thermodynamics model was employed as a fluid package of this simulation. The process converts waste plastic to fuel, which was taking places in two stages in an Aspen Hysys Simulation Environment such as i) A conversion of plastic wastes into Vapour-Liquid Fraction (VLF) with small quantity of char residue using conversion reactor (Pyrolytic Reactor) and ii) Separation of produced Vapour-Liquid Fraction to pyro gases and liquid fuel with the help of water tube Condenser. The obtained results demonstrated that, a conversion of Poly-Styrene (PS) into liquid fuel is up to 88.7% was optimum than other plastics Poly-Ethylene (PE) 81.95% and Poly-Propylene (PP) 83.54 %. The simulated model can help an interested to researcher in knowing expected products and their individual component for better understanding and scale-up studies.
