I currently have an exhaust stream that contains the solvent NMP (N-methyl-2-pyrrolidone). I would like to condense the NMP in the exhaust and recover it to use as a solvent to clean or resell to others. The exhaust stream is at a temperature of about 120 degrees Celsius. The concentration of NMP in the exhaust is very low, somewhere on the order of less than 5%.

I am thinking that a chiller or heat exchanger should work for this. Does anyone have any suggestions regarding where I can find more information to help me develop this process?

Thank you in advance.
