WebHello everyonewelcome back to my YouTube channel chemicaladdaHere in this video we will discuss difference between batch reactor, CSTR and PFR#batcheactor#CS... WebThe CSTR-in-series model considers a sequence of completely mixed tanks as a fit to sequential zones of the non-ideal reactor. In a sense, this is similar to considering the PFR as a sequence of non-interacting differential volumes. Thus, both the E and F curves will be the sum of a series: 1 / E (1)! N Nt N NNt e N
