Disadvantages of cstr

http://definitionmeaning.com/Medical/cstr Cascades of CSTRs, also known as a series of CSTRs, are used to decrease the volume of a system. As seen in the graph with one CSTR, where the inverse rate is plotted as a function of fractional conversion, the area in the box is equal to where V is the total reactor volume and is the molar flow rate of the feed. When the same pro…
