Cstr washout curve

WebA unique feature of a biological CSTR is the washout point. When the flow rate is increased so that the microbes can no longer reproduce fast enough to maintain a population, the … WebConcentration curves at different Peclét numbers The 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

Webresulting curve of C(t) can be transformed into a dimensionless residence time distribution curve by the following relation: 0 ( ) N vC t E t 0 dN vC(t)dt; N0 vC(t)dt where N0, v, C(t) indicate the total amount of tracer, volume flow rate, and concentration of tracer measured at outlet with residing time = t. 0 ( ) ( ) C t dt C t E t WebA unique feature of a biological CSTR is the washout point. When the flow rate is increased so that the microbes can no longer reproduce fast enough to maintain a population, the microbes wash out of the tank, and the reaction ceases. This washout point represents the limits of maximum flow rate for operation. IV.D.2 Classification greatech organization structure https://heating-plus.com
