METHOD AND PLANT FOR RECOVERING MATERIAL AND/OR ENERGY FROM PHOSPHORUS-CONTAINING WASTE

摘要

The invention relates to a method and a plant for recovering material and energy from phosphorus-containing waste by means of an air-assisted smelting-gasification and/or oxygen-assisted smelting-gasification process in metallurgical shaft furnaces. In said method, the phosphorus and/or phosphorous compounds reaching the gas phase in metallurgical shaft furnaces during the method-specific recovery of material and energy from phosphorus-containing waste by means of air-assisted and/or oxygen-assisted smelting-gasification can be easily separated and be used for metallurgical material recycling processes without having to go through a complex wet gas purification process combined with an integrated quenching step to obtain cooling to about 5°C, e.g. because of organic residues contained in the waste.
