## How to estimate the equipment cost?

(OP)

Hello, friends！

I have completed 2 sets of process simulations using Aspen Plus. I want to estimate the cost of the heat exchangers, pumps, compressors, distillation towers and other equipment that appear in the process.

However, I read a lot of literature and found that the formula they used was more complicated, and the calculated equipment price had a small gap with the real price.

I am currently in the conceptual design stage, so I want to use the aspen simulation results to estimate the approximate equipment price roughly.

I hope you can recommend some articles or books, thank you very much!

They often have access to proprietary books and updated information on process plant.

You need really to define your estimate requirements and many people use the definitions of the AACE in terms of accuracy and variation. A "rough" price is very indeterminate. +/- 50% or +/-20%?? Both are "rough" prices....

Alternatively obtain budget prices from one or two vendors of the large cost items.

They provide block process diagrams, equipment estimates and production cost estimates; all for a price.

P.E. Metallurgy, consulting work welcomed

I have used Aspen Plus to complete the process simulation and obtained the simulation results of tower height, tower diameter, heat exchange area, etc. Therefore, I hope to use these simulation results to estimate the equipment cost roughly. It is not required to be very meticulous, such as adding labor costs, depreciation costs, etc., but hope that each device has a simple calculation formula, and there are several parameters related to conditions such as temperature and pressure.

I've been working 10 years in China , quite easy to get multiple quotes for equipment . The main difficulty is to find the right supplier .

Other possibility is to work with engineering companies who have large data base ( TCC is the first coming to my mind) .

For reactor you need to be more specific about the metallurgy : CS , SS ,alloys or glass lined .

In China you have many reputable companies for glass lined reactors ( De dietrich, Pfaudler and local brands ), for steel you need to approach local manufacturers .

Good luck

Pierre
