As the title says, I encountered such a problem in the simulation calculation. Calculate a distillation tower. There are two feeds at different positions on the tower. The composition of the two feeds is different. Now I want to use the CASE STUDY tool to determine the optimal feed positions of the two feeds. The purpose of minimizing the load of the reboiler at the bottom of the tower has been achieved. Can this be done? If so, how to set it up? Please give some advice from experts. I once tried to first fix the feeding position of the A-share material, and then check the best feeding position of the B-share material. Then, in turn, fix the feeding position of the B-share material, check the best feeding position of the A-share material, and finally regard the feeding positions calculated by these two parts as the best feeding positions of the two strands of material. Is this right?
The case study in proII is similar to the sensitivity analysis in aspen, but it is not the same as the case study in aspen. To calculate a distillation tower, there are two feeds at different positions on the tower. The composition of the two feeds is different. To determine the optimal feed position of each of the two feeds, the parameters can be set separately before calculation. This is the key to the problem
Thank you for the above. I used PRO2 for calculation. If PRO2's CASE STUDY can determine the optimal feeding position of two different feeds, then how to set it specifically? Can you please explain in detail? Thanks:) . If CASE STUDY cannot solve this problem, is there any other way to solve this problem using PRO2?
I also encountered this problem, I used two methods: 1. First keep one feed position unchanged, and then change the feed position of the other feed to obtain their respective optimal positions. ; 2. Change the feeding position of the feed materials at the same time to obtain their respective optimal positions. However, I seem to find that the results obtained by the two methods are not the same. Can an expert analyze it? This post was last edited by Thinking Fish on 2009-3-17 16:18 ]
