8/2/2019 Acetone Production Plant Design
1/25
Your Role: You are a manager for RiceUtility Production, and you missed themeeting with the consultants design team.Youve been given their PowerPoint file.
You have to let the other two managers onthe committee know what you think of theproposed design.

Analysis
What was the point of the processflow diagram you just saw? Is thisthe teams recommendeddesign?
What is the team trying to tell youabout their work?
Are you impressed by their designso far? Why is it good?
Go back for a second look.
What should the heading be?

Cost Analysis
$243,000 /yr profit from given base case
~1 per pound of acetone product profitmargin

If these are the specifications, whatcriteria will you be looking for in theteams design?
What does the team need to show youto convince you the design will dowhat is needed?
Did the team meet these requirementsin its design solution? How do youknow?

Modeling Issue
UNIFAC VLE Model does not accuratelypredict x-y diagram at high acetoneconcentrations
NRTL is best property package for
acetone/water binary systemBased on DeChema VLE data

Options
1) Use extractive distillation methods
2) Purchase 39MM lb acetone (openmarket)
3) Produce 97.6% acetone

1) Extractive Distillation
3 Solvents 1,2 dimethoxyethane (Diglyme)
Acetonitrile
N-Methylpyrrolidone (NMP)
Case Study: Diglyme
Prohibitive Cost $6.765 MM /yr to purchase Diglyme
Additional Column

16/25
How do you know the cost of extractivedistillation Is prohibitive?
Why is the Diglyme case of interest?
Is an additional column a solution orpart of the cost?
Is extractive distillation theh usualmethod of making acetone?
In regard to the previous slide:

2) Purchase Acetone
Purchase 39 MM lb per year acetone for$10.92 MM
Shut down acetone production
Minimize investment losses

18/25
How does the team know the cost willbe this much?
What has been the cost trend foracetone in the past?
How much of a loss will be avoided?
How do you know?
In regard to the previous slide:

3) Produce 97.6% Acetone
Need to add 3 heat exchangers
Renegotiate deal?
Break-even point
8/2/2019 Acetone Production Plant Design
20/25
In regard to the previous slide:
What about the break-evenpoint?
What would it cost to produce
acetone at this purity?
Is that purity acceptable?
What is this slide telling us aboutthe option?
What do these three bulletpoints have in common?

Recommendations
Buy acetone off open market
Dissolve acetone production facility
Recover maximum amount of lost $$

Conclusions
Adjustment of property package identifiedseparation difficulty
Possible solutions Extractive distillation
Purchase acetone on the open market
Renegotiate contract for lower acetone purity
Purchase acetone on open market is best

This team puts its conclusions at the end and didnot use informative headings on its process flowdiagrams. The headings do not outline the
argument.
A pitch that presented the recommendation firstand gave evidence of calculations to support
claims would have been more persuasive.The PPT cant reinforce the oral message orpersuade readers on its own.
