Ammonia waste heat refrigeration

The process is somewhat similar to ammonia refrigeration, where a compressor is used to increase pressure, followed by throttling and heat exchange through ammonia evaporation, in a continuous cycle. In ammonia waste heat refrigeration, the evaporated ammonia first dissolves in water; then, a pump is used to increase the pressure of this ammonia-water mixture. The pressurized mixture is sent to an ammonia distillation tower for purification, which can achieve a purity level of 99.8%. After that, throttling and heat exchange through evaporation occur again, in a continuous cycle. In this process, the heating source for the reboiler at the bottom of the ammonia distillation tower can utilize waste heat, which is why it is called the ammonia waste heat refrigeration process. Replacing compression-based pressurization with pump-based pressurization can significantly reduce equipment costs; at the same time, it allows for the utilization of waste heat, which is advantageous for those generator projects that have access to such waste heat. I wonder if anyone on the forum has done this.
