A method for removing ammonia from a gas comprising HCN, ammonia and water, by first contacting the gas with aqueous ammonium phosphate to remove ammonia from the gas, and then passing the resulting ammonium phosphate solution through an electrolyzer to convert oxalates and formates into hydrogen and carbon dioxide.

Method for removing ammonia from a gas comprising hydrogen cyanide, ammonia and water

A process for nondestructive heating and supplying of ammonia feed gas wherein high quality ammonia (typically greater than 90% and as high as 99%) is preserved at temperatures well in excess of the conventional limit of 230&deg; C. (typically from 400 to 700&deg; C.) by controlling the selection of metal surfaces in contact with the hot gas, the bulk temperature of the gas, the wall temperature, the pressure, the contact time, and the spatial surface density. Such hot gases are particularly useful for the manufacture of hydrogen cyanide.
