On Aspen simulation for the separation of mibk, isopropanol, propanone, and water
Thread Content
The current composition is as follows: isopropyl alcohol: 2.5%, water: 2.5%, MIBK: 92%, propanone: 3.0%. The temperature is 70 degrees Celsius and the pressure is 0.115 Mpa. A distillation column is to be used in Aspen to separate isopropyl alcohol, propanone, water, and MIBK. No matter how I try to simulate it now, a large amount of MIBK gets carried along, resulting in a MIBK content of 70% in the light components. I was wondering if anyone knowledgeable could help answer the following question: how can I set things up so that MIBK is not carried along?
I can try to figure it out by myself, or maybe someone can tell me whether these substances cannot be separated through distillation
This is closely related to vapor-liquid equilibrium. Do you have all the parameters for the binary interactions in your system? What physical property method to use?
I simulated it using ProII
