Abstract:
     This invention, concerning processing of delute ammonia water, is an improvement of the technology for producing ammonium bicarbonate. It adopte the closed water circulation process with fractionation, using a fractionating column without dephlegmator. The equipment is simple and easy to operate. This invention has solved the problem of excess delute ammoniu water in the ammonium bicarbonate production. It improves the utilization of ammonia, lowers the consumption of copper and acetic acid. and also reduces environmental pollution due to ammonia.
