Hi.. i am currently doing a project to separate a mixture of benzene from cumene.
I need to know roughly what is the cost of a distillation column that is used in the industries.
Rough specifications of column:
Height= 22m
diameter = 1.5m
Number of trays = 9

i hope that i can get a rough estimate of the cost based on these specs.

Figo:

I don’t know what your level of University learning is because you haven’t filled in your personal profile, but I’ll assume it is your last year. If that is the case, you must have received instructions or lectures on determining the essential data to generate an estimate of equipment costs. The essential data for determining the cost of a distillation tower are (as you should know):

1. Height = 22 m
2. diameter = 1.5 m
3. Number of trays = 9
4. Material of Construction = ?
5. Shell thickness = ?
6. Vessel heads = ?
7. Vessel weight = ?
8. Vessel nozzles = ?
9. Vessel structural steel = ?
10. Vessel ladders & platforms = ?
11. Vessel insulation = ?

You’ve identified the first 3 items. You have to specify the other missing items or eliminate them from your estimate. The real critical ones are the Material of Construction and the Shell thickness. With these, you calculate the weight of the vessel and then apply a unit monetary fabrication cost – such as US$50/lb. The unit price of the vessel will depend on your location, the size of the vessel, the wall thickness, the material(s), the quantity of welding, the fabrication codes, the market situation, the availability of materials, the competitive market situation, and many other factors. You can obtain a rough estimate by calling or contacting a shop and simply asking them a direct question as to their verbal estimate of a typical unit fabrication price.

There is a software (or Excel spreadsheet) called CAPCOST. Send me your email, I can send the spreadsheet to you. Or you can use textbook to determine the distillation tower cost.

Hi.. can you also send CAPCOST to my email?? i badly need it for my exam... my email ad is myth_marj@yahoo.com Thanks!

I don't think it is freely distributable. Read Zauberberg's reply.
A nice reference page can be found at Wilcox' cost page.

And don't forget utility systems, auxiliary equipment, control loops, transport and installation expenses. Accounting for these items, the total price of your distillation tower will reach the value 2-3 times higher than the cost of tower fabrication.

Hi Dylan
if there isnt problem about violation, could you send me a copy of CAPCOST to my mail please, this is my mail: resmihadi@gmail.com.

regard
resmi

there is a text book that tells you how to calculate initial design and cost of equipment called Coulson and Richardson Chemical engineering volume 6.

Likewise, is it possible to sent it to me too. chrisvanlang@gmail.com

Hi Dylant
could you send me a copy of CAPCOST,
this is my mail: aliefangga@hotmail.com

thanks..

Hi Dylant
Can you send me a copy of CAPCOST, to the following adress:zeulsoarelui@yahoo.com
Thanks in advance!

Dylant:
Could you please do the same for me?
My e-mail is : johnvillada_1@hotmail.com
Thanks in advance!

pls send to me too.. leon_future@hotmail.com
thx a lot!

me too please...could really do with this...justian02@ntlworld.com
Thx.

Hi...yet another desperate student seeking resouce management in terms of the CAPCOST excel sheet... please please please Dylant could you send me the sheet asap? Thanx, my email adress is:
micah3eight@yahoo.com

Can you send the CAPCOST spreadsheet to ngavu123@yahoo.com. I desperately need it for my final project

Thank you

Dylant,

I am as desperate as the rest of you are, please - I really mean please - if you would, to send me a copy of this wonderful program (CAPCOST.xls) to my email address:

pj.adams@ymail.com

Really appreciate,

Pete Adams
