Sb. Yu et al., SIMULATION OF MULTISTAGE CATALYTIC STRIPPING WITH A NONEQUILIBRIUM STAGE MODEL, Computers & chemical engineering, 21(4), 1997, pp. 409-415
A nonequilibrium stage model of a multistage gas-liquid-solid reactive
separation process is developed, in which the multicomponent mass and
energy transfer between liquid and solid phases are taken into accoun
t. An algorithm based on a differential homotopy continuation method i
s demonstrated. A simulation of a catalytic stripping with a condensat
ion of phenol with acetone to produce Bisphenol-A and water is carried
out. The prediction is in good agreement with the experimental data i
n a pilot plant. Compared with a liquid-solid quasihomogeneous model,
calculations by our model are more precise. Copyright (C) 1996 Elsevie
