| Abstract: | It plays a very important role in study the solvent dehydrate distillation column to improve the separation of acetate acid from water.Ternary heterogeneous azeotropic mixture of acetic acid-water-butyl acetate was studied with residue curve maps(RCM).One plant of the dehydration columns of the petrochemical company was simulated by ASPEN PLUS software.Influence of different factor effect on the azeotropic distillation was analyzed and optimized with the field data.When the reflux ratio was 0.76,aqueous ref... |
