A simple problem of separating ethanol from water; I need guidance from experts
Thread Content
The feed stream has a flow rate of 20 tons/h; the mass fraction of ethanol is 5% while that of water is 95%. It is required that the quality fraction of the ethanol product be ≥99% and the ethanol recovery rate be ≥95%. The temperature and pressure of the feed can be set arbitrarily; design a separation process accordingly. I need some guidance from experts; I have to use Aspen for simulation {:1_90:}
Such the most common designs hardly deserve any discussion; don’t expect anyone to give you guidance on blank sheets. One can only find information on their own to get started first; once problems arise, they can be shared and someone will provide answers
If distillation technology is used, there are well-established processes available. It mainly includes: heterogeneous azeotropic distillation and extractive distillation.
Distillation is possible; using PROII for simulation should not be a problem. Your conditions alone are sufficient
...To put it simply, anyone who has read books on chemical engineering can do it.
Ethanol and water form an azeotrope; distillation can yield aqueous ethanol with a concentration of about 95%, which can then be dehydrated using pervaporation membrane technology to produce ethanol with a concentration of 99%.
