STUDY ON DOUBLE-EFFECT DISTILLATION PROCESS FOR SEPARATING METHANOL-WATER USING ASPEN PLUS V10

Methanol (also known as CH3OH, methyl alcohol, hydroxymethane, wood or carbinol) is a widely used primary raw material. It one of the first organic chemicals to find extensive laboratory and industrial use. water are ideal binary systems that can be separated by conventional distillation. This study aims separate methanol-water using simulated double-effect distillation process in Aspen Plus. To obtain higher purity methanol consider high energy consumption process, with double column was used. Furthermore, single-column processes Plus software. The software version this simulation V.10 NRTL thermodynamics methods interaction parameters. effect equipped heat exchanger, splitter, pump. Moreover, design specification needed get wanted.
