October 12-15, 2003 Via Naviglio Vecchio 4 6600 Locarno Switzerland 1 PRESENTATION OUTLINE THERMOSELECT • Company Information • Technology • Karlsruhe Plant / Germany • ASR Processing (Automotive Shredder Residue) • Chiba + Mutsu Plant / Japan 2 COMPANY INFO THERMOSELECT ¾ Company founded in 1989 ¾ 1989 – 1991: degasification, Laboratory scale studies of waste carbonization and gasification ¾ 1991 – 1992: scale Development and erection of an industrial pilot plant in Fondotoce / Italy ¾ 1992 – 1998: optimization demonstration Fondotoce plant operation, process and technology ¾ 1998 – 1999: Erection of commercial plants in Karlsruhe / Germany and in Chiba /Japan ¾ 150 employees, headquarter in Locarno /Switzerland, manufacturing subsidiary in Dottikon / Switzerland ¾ Licensees: • JFE Engineering, Japan (Kawasaki Steel + NKK) • Daewoo Engineering, Korea 3 PROCESS OVERVIEW THERMOSELECT H2, CO, CO2, H2O Waste of all kinds Synthesis Gas Production of 1200°C High Temperature Reactor Quench Synthesis gas scrubbing Hydrogen Methanol Ammonia or Power generation Scrubber Sulfur Process water treatment Degassing Channel Clean water Salt Press O2 Homogenization reactor Zinc Concentrate 2000°C 1600°C Metals and Minerals Oxygen facility 4 SYNTHESIS GAS SCRUBBING THERMOSELECT Safety Flare Syn. gas Acidic Scrubber Quench Heat Exchanger Degassing Filter Feed tank Alkaline Scrubber Water lock De-dusting stage Desulfurization Filtration Filtrate Regeneration Sludge Additive, new Sedimentation Additive Iron Chelate Sludge Filtration Drying Air Filtrate Sludge back feed Raw water buffer Syn. gas scrubbing Water treatment Oxidation Sulfur Pure syn. gas Products 5 THERMAL TREATMENT, GASIFIER THERMOSELECT Exothermic Reactions CO2 CO 2nCO2 + mH2O C + O2 C + 1/2 O2 2 CnHm + (2n + m/2) O2 Endothermic Reactions 1200 °C Quench C + H2O CO + H2O C + CO2 CnHm + nH2O CO + H2 CO2 + H2 2 CO (Boudouard) nCO + (n + m/2)H2 Controlled injection of oxygen is used to gasify organic components at temperatures up to 2000°C. The produced synthesis gas is primarily composed of H2, CO, CO2 1600 °C Metal and mineral constituents are molten Burner / oxygen lances 2000 °C Melt cooling 6 SYNTHESIS GAS SHOCK COOLING THERMOSELECT The synthesis gas produced in the gasifier is shockcooled in the quench immediately downstream. Cooling takes place in less than 30 ms. Quench 1200 °C Cooling water (pH value < 3) 30 ms 70 °C 7 TYPICAL GRANULATE COMPOSITION THERMOSELECT Metal and mineral granulate is ready for reuse. The vitreous mineral granulate leachability complies with strictest regulations. Typical metal granulate (wt%) Typical mineral granulate (wt%) 8 THERMAL TREATMENT, GASIFIER COOLING THERMOSELECT The reactor wall consists of a thermally-insulating refractory lining. Refractory The highly stable refractory material is protected by a slag coating of vitrified mineral melt. Inner Cooling Gasifier interior Liquid mineral melt runs off the slag coating.
