Plasma Gasification with Municipal Solid Waste As A Method of Energy Self Sustained for Better Urban Built Environment: Modeling and Simulation

Abstract

The plasma gasification method is known as a new technology to produce hydrogen from MSW as a fuel for power generation. Recently, it has become a crucial issue due to the rapid increasing amount of waste, along with the increasingly national population in Indonesia. The goal of waste management is as a material recovery (MR), as an energy recovery (ER) and minimizing the environment impact. The plasma gasification modeling was developed based on plasma torch technology to estimate the syngas composition and energy potential. The process simulation is optimized for mixed steam and air as a gasifying agent. This study is to obtain the essential parameter to have the better content of H2 in the syngas, better plant efficiency and lowest CO2 emission for developing urban built environment with lesser greenhouse gases (GHG). Result shows that, the ratio of Steam to Waste: 0.08 %, the air mass flow rate: 1.11∗10-3 kg/s and the steam mass flow rate: 01.11∗10-4 kg/s gain the highest molar fraction of H2 : 32.09%, Syngas Yield : 1.28 Nm3/kg, Carbon Conversion Efficiency : 5.83%, Cold Gasification Efficiency : 77.96% and the CO2 emission : 2.23∗10-4 kg/s.
