Abstract

<PICT:0477617/III/1> Concentrated solutions, suspensions, or aqueous melts of metal salts are decomposed by atomizing them into an elongated decomposition chamber and bringing them into intimate contact with a highly heated gaseous medium which effects dehydration and decomposition. The amount of gaseous medium used and its initial temperature are such that the products of decomposition which are entrained by the gas leave the chamber at temperatures still in the vicinity of the decomposition temperature. Metal salts which may be decomposed include the sulphates of silver, iron, manganese, copper, nickel, cobalt, zinc, and magnesium, the chlorides, nitrates, and carbonates of the heavy metals, the nitrates and carbonates of the earth, alkaline-earth and alkali metals, and magnesium chloride. The solutions &c. may be atomized by compressed air steam, or other suitable gas, whilst the gaseous medium may be gases of combustion, air, carbon dioxide, nitrogen, or superheated steam and it may be used at temperatures up to 1800 DEG C. In the decomposition of sulphates, sulphuric acid or oleum may be recovered from the issuing gases. As shown in the drawing, the salt solution &c. is atomized through the nozzle 22 and mixes in the chamber 21 with gases of combustion supplied from burners 23. Further heat may be supplied by means of burners 26. The issuing gases are freed in a cyclone separator 31 from solid products, partly cooled in a waste heat boiler 30, further cooled in a heat-exchanger 33 which serves to preheat air supplied to burners 23, 26, and finally passed through an electrical gas cleaner 35. In other methods of carrying out the process, the gaseous heating medium may be recirculated after separation of solid and gaseous products of decomposition and reheating.
