Description

5/5 - (1 vote)

Develop a flowsheet in Aspen Plus to simulate the following process.
A feed stream (saturated liquid at p atm) containing an equimolar mixture of acetone, ethanol,
butanol, and phenol is distilled at p atm.

Determine:
1. The concentrations of the distillate and bottoms streams
2. Vapor and liquid composition profiles along the column

Some specifications:
1. Use the UNIQUAC thermodynamic model
2. Distillation column has 9 trays, with the feed entering at the top of the 5th tray; Total
distillate flow is ½ the inlet flow and reflux ratio is 5

3. If your roll number is CH18Bxyz, then p = 1 + x.yz. So for CH18B056, p =1.56 atm; for
CH17B123, p=2.23 atm

Deliverables (DUE DATE: 30 Jan 2022, 11:00pm)
1. One page report in pdf format showing the flowsheet, mass balance and vapor and liquid
composition profiles along the column
2. Aspen Plus file (named as per your Roll Number)
