A 90% conversion design produces a 1.68-m3 reactor Figure 2.25 Matlab program for autorefrigerated reactor. 2.7 ... the conversion is only 85% in the first reactor. If the 2-CSTR design has more potential control problems than the 1-CSTR design, wewould expect the 3-CSTR design to be even worse. This is precisely ... each reactor is further reduced (14.4 m3with diameter 2.09 m), so the total reactor volume of the thr ee vessels is 43 m3, which is only 16% of the volume of the reactor in the 1-CSTR design. ...
