Feed temperature is a very important design parameter in tubular reactors. A low feed temperature results in low reaction rates. So a long reactor is ... 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. ...
