WebSep 23, 2024 · CSTRs allow for the continuous production of the desired chemical without the need to repeatedly empty and fill the tank. Figure 24.1 displays diagrams for a batch reactor and CSTR. The molar flow rates of species \(j\) into and out of the CSTR are denoted by \(F_{j0}\) and \(F_j\), respectively, with units of \(\text{mol/s}\). http://websites.umich.edu/~essen/html/course/lectures/eleven/index.htm

WebJul 24, 2024 · 1.4 Continuous-Flow Reactors. Continuous-flow reactors are almost always operated at steady state. We will consider three types: the continuous-stirred tank reactor (CSTR), the plug-flow reactor (PFR), and the packed-bed reactor (PBR). Detailed physical descriptions of these reactors can be found in both the Professional Reference Shelf ( … Web对pfr、cstr级联以及pfr-cstr级联的停留时间分布（rtd）进行了测量，结果表明组合式pfr-cstr级联的rtd比单独连续搅拌罐式反应器级联的rtd稍长。 对于反应结晶，由于PFR的RTD较窄，因此PFR-CSTR级联系统的产率较高，从而最大限度地减少了未发生反应的材料与杂质 …
