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. ...
