Simulation of Gasification Parameters Using Phenomenological Study for MSW Feedstock Based on Plasma Technique: A Review

The paper presents a subtle review of emerging gasification technologies to tackle municipal solid waste through effective waste-to-energy conversion systems. Plasma gasification is a state-of-the-art technology that uses highly flammable inert gases to ionize volatile products at elevated temperatures. Pyrolysis is often viewed as an alternative to incineration as the process has a major contribution toward dioxins and furans. However, a plasma-embedded gasification system that produces cleaner energy outputs with relatively higher energy content may turn out to be an attractive alternative option for RDF-based fuels. Plasma is often embedded into torches to produce a highly flammable arc of inert gas that converts RDF from MSW waste into syngas in the presence of a suitable oxidant. This paper reviews modeling approaches made for effective gasification systems using various process-flow simulation software like Aspen Plus. Effects of different gasification parameters like steam/MSW ratio, equivalence, and consumption rates were evaluated for better prediction over a wide range of waste loading under variable environmental conditions.
