The issue of the reactive distillation feed position
Thread Content
The last edit to this post was made by Hidden Pig on 2017-5-8 at 17:20. According to the information related to reactive distillation, the two compounds A and B, which serve as raw materials, have their feeding positions determined based on their volatility. Generally, the light components (with high volatility) are fed at the lower part of the tower, while the heavy components (with low volatility) are fed at the upper part of the tower. Now the question arises: due to process constraints, the volatile component a is fed as a gas phase, while the light component b is fed as a liquid phase. Does this mean that a can only be fed in the lower part of the tower, and b in the upper part? I wonder if this approach will work?
The feed location is near the region with a composition similar to that inside the tower; although feed A is in gaseous form, it should be placed at the upper part of the tower, where it can enter the gaseous phase space.
