ECO-WASTE Objectives The objective is to build and demonstrate a commercial operating PyroArc plant south of Trondheim in Norway. The capacity of the plant is 10 500 tonnes of waste per year and it will be possible to treat all sorts of waste, except radioactive. The plant will recover the energy from the combustible part of the waste and slag and metal from the non-combustible part. The energy will be recovered as hot water and electric power. The hot water will be utilised in the local grid and the electric power will be used partly internally, the rest being exported on the local net. Slag can be sold as a construction material while the metal can be sold to foundries for the production of simple foundry products, for example counter-weights on trucks. The plant will generate no, or very little, residue (for example ash) which has to be put in landfill. The PyroArc waste to energy process utilising gasification, plasma and vitrification technology Challenges Owing to increased public awareness for the environment and new regulations, there is a rising market for gasification processes. Many attempts have been made to achieve the great benefits of waste gasification. Most of the available, commercial gasification processes for waste today are combusting the produced gas directly after the gasification to prevent tar causing operational problems in the system downstream. The results are processes that are more or less equal to traditional incineration processes. Heading needed here The two stage PyroArc process is decomposing all the tar components formed in the gasifier by an integrated plasma generator into a decomposition reactor immediately after the gasifier. With this, all the advantages of using a gasification process are being achieved. It is producing a clean fuel gas, recovering the sensible heat, decomposing all toxic and harmful components, recovering energy and material efficiently and no, or very limited, amounts of waste is being produced that has to be put in landfill. 32 The PyroArc Process The process comprises a feed system, a melting shaft gasifier, a plasma generator system, a decomposition reactor, a gas quencher, an energy-recovery system and a dust collection and gas cleaning system. Solid waste materials are charged into the shaft gasifier through a lock hopper system. The organic components are converted into a partly oxidised syngas, while the remaining inorganic species melt. The syngas consists mainly of carbon monoxide, hydrogen, carbon dioxide, water and nitrogen but is also associated with a rather high content of tar-forming components (complex HC) and chlorinated hydrocarbons. Depending on the moisture of the feed, the temperature of the syngas will be around 400 – 700 °C when it leaves the gasifier. In the consecutive plasma generator system and decomposition reactor, the gas decomposes completely due to the high temperature (3000 – 5000 °C) of the plasma-jet and its strong dynamic impact on the syngas which provides a homogeneous temperature of more than 1 100°C to all fraction of the syngas. Liquid waste will be fed directly into the plasma generator system.
The most important feature of the PyroArc process is that all the waste material that leaves the process has been exposed to sufficiently high temperatures for the decomposition of toxic elements. The products are a fuel gas, a leach resistant slag, molten metal and small amounts of secondary dust that may be subjected to the recovery of zinc. About 65% of the energy content of the waste is available as heat of combustion in the fuel gas, and almost 30% as sensible heat. The uniqueness of the process is the plasma generator system and the way it is used to decompose the syngas into a harmless fuel gas without any contents of tar. The main features of the plasma generator system are: 1. a complete decomposition of the highly toxic halogenated organic compounds, 2. the higher heating value of the produced fuel gas, and 3. the decomposition of any tar components. The flow sheet of the PyroArc process. Project structure EnviroArc technologies (Norway) is the coordinator of the project. The partners will be ScanArc (Sweden), SINTEF (Norway), Trønder Energi (Norway), Sita (Sweden) and CF Nielsen (Denmark). The execution of the project will be carried out in three groups of tasks. The different groups are: 1. R&D focusing on a special topic within the pretreatment, thermal unit, gas cleaning and energy production system 2. design, construction, commissioning and start up of the PyroArc plant 3. commercial operation of the plant. The Plasma generator. 33 INFORMATION References: NNE5-702-2001 Programme: FP5 - <strong>Energy</strong>, Environment and Sustainable Development Title: <strong>Energy</strong> from Waste by Gasification and Plasma Cracking of Syngas with Multiple Recovery and Inert Rendering of Residues – ECO-WASTE Duration: 48 months Contact point: Steinar Lynum EnviroArc Technologies Steinar.Lynum@EnviroArc.com Partners: EnviroArc Technologies (NO) ScanArc (S) SINTEF (NO) Trønder Energi (NO) C.F.
