The below task needs to be done. Please look into the details.
The work must be all ORIGINAL, and any form of copy-pasting will be rejected.
Being well-versed in APA Referencing would be an added advantage for the applicant.
Your task is to design a distillation column to separate 1000 kmol/h of a multicomponent mixture consisting of 8 mol% n-pentane, 42 mol% n-hexane, 38 mol% n-heptane and 12 mol% n-octane with 98% recovery of n-hexane in the distillate and 98% recovery of n-heptane in the bottoms.
You should determine:
i) optimum reflux ratio,
ii) optimum feed plate,
iii) total number of equilibrium stages,
iv) total number of real stages,
v) column height,
vi) column diameter,
vii) estimate of the column cost
You should use the following design specifications:
• Pressures: Pressure of column = 405.3 kPa
Pressure of reboiler = 406 kPa
Pressure in condenser = 404 kPa
• Total condenser and partial reboiler
• Sieve trays with 24-inch tray spacing
• Feed flow rate is 1000 kmol/h of saturated liquid
• Feed composition: 8 mol% C5H12, 42 mol% n-C6H14, 38 mol% n-C7H16, 12 mol% n-C8H18
• n-C6H14 recovery in distillate: 98%
• n-C7H16 recovery in bottoms: 98%
• Trays operate at 75% of flooding
The project should be completed in teams of 3. You are expected to use process simulation tools such as HYSYS to assist you in completing a rigorous design of the distillation column. Also, you should conduct hand calculations using a shortcut method to check the simulation results and discuss any differences that you find. You should clearly explain your methodology and justify any assumptions you have made.
The final report should contain the following sections:
i) Cover page
iii) Table of contents
iv) List of figures
v) List of tables
vii) Problem statement
viii) Hand calculations – methodology and results
ix) Simulation results
x) Results summary and discussion
