A large number of organizations, the world over, are developing plasma gasification systems for treating trash of various kind Generating useful byproducts, while minimizing the environmental pollution. What is Plasma? : What is Plasma? Plasma is the fourth state of matter (other three being solid, liquid, gas). It is an Ionized gas existing in nature. Lightning is an example from nature. What is plasma Gasification? : What is plasma Gasification? Gasification is a process that converts carbon-containing materials, such as coal, petroleum coke, municipal solid waste, or biomass, into a synthesis gas, (syngas), composed primarily of carbon monoxide and hydrogen. Various methods of producing Plasma Arc : Various methods of producing Plasma Arc Plasma from discharge tubes: : Cascade process of Ionization: : Modern high power plasma torch: Effect of temperature on state of matter : Effect of temperature on state of matter Treatment of Waste in Plasma Gasifier : Treatment of Waste in Plasma Gasifier Plasma torch can process both organic and inorganic materials Organic matter is converted into sysgas (Gasification). Inorganic matter is converted into byproducts (magmavication). Plasma Arc Gasification plant : Plasma Arc Gasification plant Components of Plasma Gasification system : Components of Plasma Gasification system Trituration and conveyor section Pyrolysis chamber with plasma torch/torches Gas reformer and heat exchanger Gas cleanup filter Trituration and conveyor section : Trituration and conveyor section To feed garbage into the converter, almost all plasma facilities have a conveyor system. Pyrolysis chamber with plasma torch/torches : Pyrolysis chamber with plasma torch/torches : Gas ventilation After burner Gas reformer and heat exchanger Steam turbine Gas cleanup filter : Gas cleanup filter Gases produced by pyrolysis mainly comprise CO, hydrogen and hydro carbons, carbodioxide and nitrogen. Byproducts obtained : Byproducts obtained The byproducts obtained in this process are, vetrified glass metals Sodium bisulphide HCL Ethanol Distilled water Cost Analysis : Cost Analysis Cost of Electricity Capital cost : Capital recovery factor, i=rate of interest, n=plant lifetime : Efficiency of system : Efficiency of system Other well known Waste Management Techniques….. : Other well known Waste Management Techniques….. Landfills: Disposing of waste in a landfill Incineration: Destroying waste by burning it Anaerobic digestion/ biomethanation: In this process the waste undergoes biodegradation in the presence of methanogenic bacteria etc., Pros &cons over other methods : Pros &cons over other methods Compared to combustion /incineration technology, it creates much less atmospheric pollution. In techno-economic terms, oxides of nitrogen and sulphur are not emitted during normal operation because the system works in the absence of air. Toxic materials become encapsulated and are therefore much safer to handle than the toxic ash left by combustion processes. Conclusion : Conclusion Gas turbine and MSW-boiler-hybrid combined cycles are an effective approach to recovering energy from MSW more efficiently. The combined cycle has many advantages over separate single fuel power plants and dramatically increase the efficiency of EfW (Energy from Waste) Conversion.
