In the present research paper incorporates the steady state simulation of waste plastic thermolysis process and modelling for the conversion of hydrocarbon product from waste plastics such as polyethylene (PE), polypropylene (PP) and polystyrene (PS) with the assistance of Aspen Hysys V9 simulator. This simulator was used to design the pyrolytic reactor model for waste plastic thermolysis process. A Peng-Robinson thermodynamics model was employed as a fluid package of this simulation work. The simulation process of plastic pyrolysis in the simulation environment, was taking places into two stages such as i) A conversion of plastic wastes into vapour-liquid fraction (VLF) with small amount of char-residue using conversion reactor (pyrolytic reactor) and ii) separation of produced vapour-liquid fraction to pyro-gases and liquid-fuel with the aid of water tube condenser. The obtained results demonstrated that, a conversion of polystyrene into liquid fuel is up to 88.7% has been optimum value than other plastic wastes like polyethylene produced of 81.95% and polypropylene produced of 83.54 %. The simulated model can provide an inspiration to the researcher in knowing expected products and their individual component for better understanding and scale-up studies.
