Equipment selection for alcohol vacuum recovery

Thread Content

In my production process, ammonia is used; its strong odor requires it to be removed under reduced pressure. However, my system uses 95% alcohol, which means that when removing the ammonia, 25% of the alcohol is also drawn away. I now need to modify the equipment in order to condense and recover the alcohol during the pressure-reduction process. The current idea is to add a condenser and a chiller. The question I would like to ask everyone is: what size condenser should I choose, and is a two-stage condensation system necessary? What size chiller should I select? When I contacted the manufacturers, they all recommended air-cooled chillers, with the outlet temperature set around 15°C. The vacuum in my system is around 0.07 MPa to 0.08 MPa, the system temperature is 55°C, and the recovery rate is 50 kg/h. May I ask what the outlet temperature of my system is?
