METHOD OF COMPLETELY UTILISING IN MATERIAL AND EMISSION-FREE MANNER ALL COSTITUENTS OF MUNCIPAL AND INSUSTRIAL WASTE THROUGH HIGH-TEMPERATURE RECIRCULATION AND FRACTIONATED, MATERIAL-SPECIFIC CONVERSION OF CRUDE SYNTHESIS GAS AS WELL AS APPARATUS THEREFOR

摘要

Complete material emission-less utilisation of all components of communal or industrial waste comprises: (a) converting the contents contained as pollutants in the synthesis crude gas into useful materials in separated wet treatment steps; (b) feeding the solutions containing the converted useful materials and condensates to the conversion steps and removing the useful materials by stepped precipitation and ion exchange reactions and separation reactions with recovery of the process water; and (c) cold drying the purified synthesis gas and recycling the recovered process water together with the condensate from cold drying to the individual conversion steps. An apparatus for carrying out the process is also claimed.
