Distillation and dehydration of NMP from lithium battery recycling liquid
Thread Content
After checking some information, it is found that most processes currently use a two-tower series dehydration setup. A simulation was carried out using Aspen, and the results showed that the reflux ratio in the dehydration towers is relatively low, around 0.1. I would like to ask those among you who are familiar with this process to provide their analysis.
Bro, to what level of water content can you achieve with dehydration?

In double-tower distillation, it is very difficult to achieve a wastewater concentration of 300 ppm for discharge in one of the towers.
