ABSTRACT:
A method of condensing a gaseous mixture of ammonia carbon dioxide gas and water vapor to produce an ammonium carbonate solution with minimum formation of ammonium carbamate includes passing the gaseous mixture into a condenser and cooling the condensing surface to cause the gaseous mixture to condense to form ammonium carbonate solution at a temperature at which formation of solid ammonium carbamate may occur. An aqueous liquid is discharged onto the condensing surface of the condenser, the liquid having an ammonia concentration below about 260 grams per liter to maintain the concentration of ammonia and carbon dioxide on the condensing surface below a concentration at which ammonium carbamate tends to form.
