NOVELTY - An ammonia-carbon in melamine tail gas is separated by sending melamine device to tail gas through injector with water absorption, preparing carbon-ammonia stored in spraying absorption tank, introducing residual carbon dioxide gas containing low ammonia into washing tower, emptying to obtain 50 ppm of ammonia tail gas, washing tower with urea to generate low pressure steam for spraying absorption tank and sending to heated low carbon ammonia, evaporating liquid phase of ammonia gas and carbon dioxide, separating evaporated ammonia gas and carbon dioxide in rectifying tower, and discharging.    USE - Separation of ammonia-carbon in melamine tail gas (claimed).    ADVANTAGE - Separation process has no wastewater discharge, saves water, reduces steam consumption, and protects environment.    DETAILED DESCRIPTION - An ammonia-carbon in melamine tail gas is separated by sending melamine device to tail gas through injector with water absorption, preparing carbon-ammonia stored in spraying absorption tank, introducing residual carbon dioxide gas containing low ammonia into washing tower, emptying to obtain 50 ppm of ammonia tail gas, washing tower with urea to generate low pressure steam for spraying absorption tank and sending to heated low carbon ammonia, evaporating liquid phase of ammonia gas and carbon dioxide, separating evaporated ammonia gas and carbon dioxide in rectifying tower, flowing ammonia gas and carbon dioxide gas into bottom of rectifying tower, performing top to bottom counter-current contact of ammonia in rectifying, performing gas phase reaction of ammonia and carbon dioxide, transferring gas phase carbon dioxide to liquid phase, forming carbide ammonia, cooling residual ammonia gas phase by water, separating ammonia, returning separated ammonia to tower, refining ammonia gas by ice feeding machine into liquid ammonia, sending carbonated ammonia into rectifying tower, heating by steam under medium pressure to obtain liquid phase of carbon dioxide, separating ammonia, evaporating, washing top of tower with contact water, performing water absorption of ammonia gas, steaming carbon dioxide gas from tower top, keeping residual carbon dioxide, all ammonia., and water in liquid phase, forming low-carbon ammonium, discharging from bottom into distillation tower, and circulating.    DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of separation process of ammonia-carbon in melamine tail gas. (Drawing includes non-English language text).
