packed bed reactor design calculations

... different design levels of conversion on the sizes of the reactor and the condenser. A 90% conversion design produces a 1.68-m 3 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, we would expect the 3-CSTR design to be even worse. This is precisely ... each reactor is further reduced (14.4 m 3 with diameter 2.09 m), so the total reactor volume of the thr ee vessels is 43 m 3 , which is only 16% of the volume of the reactor in the 1-CSTR design. ...
