Questions about tearing flows
Thread Content
I would like to ask experts how to set up the tear flow? The process I have built requires the logistics to be recycled; it can operate normally if the process is not closed, but an error occurs once it is closed. I’m wondering whether it’s possible to use a split flow to adjust the flow parameters so that it eventually converges What is the specific approach? Could someone experienced give me some advice? . .

Use the results obtained under disconnected conditions, such as flow rate, composition, and temperature, as initial values for the circulating stream. Try repeating this process several times until the initial values are very close to the calculated values! Read the following article carefully; it might be helpful to you. Luyben W. L.. Control of a multiunit heterogeneous azeotropic distillation process. AIChE Journal, 2006,52(2):623-637 Good luck!
Databrowser (Small Glasses) – under Convergence-Tear, select the logistics items that need to be disconnected; the error value can be set relatively high at first, and then reduced after everything is working properly.
