Document Summary
Due: wednesday, april 8, 2020: wall-cooled pfr. Elementary liquid-phase reaction a + b c is carried out in a tubular pfr. Mole balance: df a /dv = -r a dx a /dv = k/v 0 [c a0 (1 - x) 2 - x / k c ] dx a /dv = 0. 0005 exp(5033/t - 16. 8) [(1 - x) 2 - x exp(3021/t - 6. 7)] The heat transfer coefficient u is 5 cal/(m 2 s k) and the diameter of the pfr is 1 m. assume temperature does not vary radially (from the edge to the center), only axially (along the reactor). Plot the new temperature and conversion throughout a 10 l reactor. Addition of the coil is extremely helpful in promoting the forward reaction. It requires energy, but this energy is likely worth using in order to greatly increase conversion: optimizing inlet conditions. Elementary gas-phase reaction a b + c is carried out adiabatically in a 500 l pfr.
