I knew the feed parameters and the required product purities, B1 and B2. l then guessed the recycle parameters of stream REC1 and carried out the simulation. after converging the simulation D2 flowrate (ultimate recycle stream) was different from REC1. I then re-guessed the REC1 flowrate, and all hell broke loose, as it wouldn't converge, l guess due estimates of the controllers, not sure. for example l put 190 kmol/h for REC1, and it wouldn't converge. is there any tricks for problems with recycle streams or any different approach from this one.
kind regards,
Akan
