In this tutorial, we will create a simulation in Aspen Plus to separate n-butane and cis-2-butene using the following design results from module Dist-006_DSTWU. The easiest model in Aspen is the DSTWU module, which requires fewer operating parameters than any of the other Aspen distillation units. DSTWU (shortcut method) For a specified product recovery (both light and heavy keys), the DSTWU column first estimates the minimum number of stages and the minimum reflux ratio, and then it calculates either the required reflux ratio or the required number of theoretical stages based on the user input.
