The original solution is concentrated by first stage MVR distillation to remove the majority of water, and the remaining concentrated solution is then subjected to second stage dehydration and third stage refined distillation processes to meet the standards for recycling. Distilled water meets the reuse standards through a deamination system, and the deamination solution and exhaust gas are further absorbed and analyzed to obtain a concentrated amine solution. This process system achieves zero environmental emissions, eliminates pollution problems, and the recovered solvents can also achieve certain economic benefits.
Among them, the MVR distillation and concentration process is the energy-saving core of this system, and adopting reasonable MVR processes for different solvents can achieve the best economic benefits and safe operating conditions.
