Process for the preparation of substantially anhydrous gases containing hydrogen chloride and carbon dioxide from chlorine, hydrogen, carbon and organic residues containing metals as impurities

摘要

The process according to the invention comprises reacting the residues at temperatures of above 2000 DEG C and pressures of 1 to 100 bar with a gas mixture promoting combustion in a combustion chamber equipped with cooling devices. The gaseous reaction products which, upon leaving the combustion chamber, have temperatures of 200 to 800 DEG C are first cooled in a first cooling zone a) to temperatures in the range from 80 DEG C to 10 DEG C. The gaseous top products are treated in a process step b) in a suitable device with concentrated hydrochloric acid in the form of droplets having an average diameter of less than 500 mu .
