PROCESS FOR THE CONVERSION AND WORKING UP OF A MIXTURE OF ORGANIC MATTER, ANORGANIC MATTER AND WATER TO A NEARLY DRY PRODUCT, AS WELL AS AN INSTALLATION FOR THE EXECUTION OF THE PROCESS AND APPLICATION THEREOF BY THE CONVERSION OF MANURE SLURRY

摘要

Process for the conversion and working up of a mixture of organic matter, anorganic matter and water to a nearly dry product, whereby the mixture is contacted with an oxygen containing gas and put to reaction in a reaction section (9) at temperatures between 200 and 320 degrees Celsius, pressures between 40 and 125 bar and reaction times between 300 and 5400 seconds. After reaction the mixture and gas are separated on the one side in a slurry phase and on the other side water vapour containing gas-phase. The heat in the latter is used for heating of the mixture and for evaporation of water from the slurry phase. Therefor the latter is led to an evaporation section, which is equipped with evaporation means and which may consist of various units, of which at least one unit contains a fluidized bed (16). Organic matter and inorganic matter, emanated from the slurry phase are caught in this bed. The evaporation section is operated at lower temperatures and pressures than the temperature and pressure of the slurry phase and gas phase immediately after reaction. Parts of the fluidized bed mass are discharged periodically or continuously as a nearly dry matter.
