Abstract

Thermal plasma gasification is a new and innovative method of waste management. In this study, the process of gasification of municipal solid waste in thermal plasma reactor has been simulated using Gibbs free energy minimization method with the help of Aspen Plus software. And validated with data from scientific sources. Most of the operational parameters such as air to waste ratio, reactor temperature, pressure to waste ratio and lower calorific value of gas have been studied by describing the manufactured syngas. The highest hydrogen content was 67%, which was calculated for gasification with steam plasma, And the lowest calorific value of the gas compared to 11/6 (MJ/Nm3) was calculated. Due to the very high temperature created by plasma, many pollutants that are a big problem for conventional methods do not affect this process.
