REMOVAL OF AMMONIA AND CYANIDE FROM SYNTHESIS GAS WITH WATER PRODUCTION

A PROCESS FOR PRODUCING AND CLEANING A SYNTHESIS GAS WHICH CONTAINS AND HYDROGEN CYANIDE CATALYTICALLY CONVERTS MOST OF THE CYANIDE TO AMMONIA WHICH, ALONG WITH SOME OF THE CYANIDE, IS REMOVED FROM THE GAS WITH WATER TO FROM A AQUEOUS SOLUTIONS OF AMMONIA AND CYANIDE. THE HYDROCARBON GAS FEED TO THE...

Zusammenfassung:	A PROCESS FOR PRODUCING AND CLEANING A SYNTHESIS GAS WHICH CONTAINS AND HYDROGEN CYANIDE CATALYTICALLY CONVERTS MOST OF THE CYANIDE TO AMMONIA WHICH, ALONG WITH SOME OF THE CYANIDE, IS REMOVED FROM THE GAS WITH WATER TO FROM A AQUEOUS SOLUTIONS OF AMMONIA AND CYANIDE. THE HYDROCARBON GAS FEED TO THE SYNTHESIS GAS GENERATOR IS USED TO STRIP AMMONIA AND CYANIDE OUT OF ONE OR MORE OF THE AQUEOUS SOLUTIONS OF THESE TWO SPECIES FORMED DURING THE PROCESS AND PASS THEM INTO THE GENERATOR IN WHICH THEY ARE CONSUMED TO FROM CLEAN WATER. A PORTION OF THE RESULTING CLEAN WATER IS RECYCLED BACK INTO THE PROCESS WHERE IS USED TO SCRUB THE SYNTHESIS GAS, WITH THE REMAINDER USED FOR OTHER PURPOSE OR SENT TO DISPOSAL.
