Document Summary

Due: monday, february 24, 2020: multiple reactors. Since this is a first order reaction, rate decreases with increasing conversion. Levenspiel plot of 1/rate would show an upward curve with increasing conversion. Damkohler number (da = k for a first-order reaction) versus conversion would look similar. For the same da, the pfr (b) yields a higher conversion than the cstr (a). For multiple-reactor systems c, d, and e, conversion will fall between the limits of one cstr and one pfr. F t = f a0 (1 - x a ) + f a0 x a + f a0 x a + f a0 = f t0 + f a0 x a = f t0 (1 + /2 x a ) Since pv = frt, v = v 0 (1 + /2 x a : derive an expression for the volume needed to achieve exit conversion x a .
