Abstract:
A method for a total material and emission-free utilization of a synthesis raw gas comprising water vapour and harmful substances, the synthesis raw gas being obtained during a high temperature recycling of all components of community or industrial wastes, comprising:a) staged separation and conversion of the harmful substances into a recoverable form and staged condensation of the water vapour in individual and separately heated wet-treatment stages to form a synthesis clean gas;b) combination of condensates and solutions obtained in the individual wet-treatment stages and containing the converted substances;c) staged separation of the substances combined in step b) and recovery of process water by one of separation, precipitation and ion-exchange reactions;d) cooling the synthesis clean gas to form a condensate; ande) returning the process water recovered in step c) and the condensate formed in step d) to the individual wet-treatment stages of step a).
