Process Simulation And Sensitivity Analysis Of Waste Plastics Gasification In A Fluidized Bed Reactor

Abstract

This paper presents a simplified process simulation model of typical waste polyethylene gasification in a fluidized bed reactor using Aspen Plus. The proposed model incorporates both physical and chemical processes, including drying, pyrolysis, combustion and gasification, using various inbuilt modules to predict the resulting product gas composition and temperature. A detailed sensitivity analysis investigating the effects of various process parameters, including equivalence ratio, bed height and steam/fuel ratio has been presented.
