RE: chemical engineering cost estimation
What type of equipment are you wanting to get cost estimations for? Anything in particular?

I have not seen such a breakdown for a whole year. I would typically take a set of mid year numbers, say June 2001, but 2001 was not a good year for averaging such statistics. Post again here if you want data for say June 2001.

I need some additional info about the technical info according to cost. I have estimated design data for all equipments.
Thank a lot for all helpings,

I opened the http://www.mines.edu/fs_home/rlmiller/capcosts.pdf and refers to certain tables that are not in the file, where I can get them.
Also, I've been trying to open http://members.rogers.com/fhcurry/CEIRev3.xls
but it appears a lot of "funny" simbols, is there any other way I can download the file?
Thanks!
RE: chemical engineering cost estimation
and it works OK.
Try right mouse, Save Target as, that should download the file to your HDD. Then you can open it in Excel.

CECPI for March 2003 (preliminary) is 398.2
CECPI for 2002 was 395.6
A comparison of March 2003 with March 2002 (391.5) shows plant cost inflation running at 1.7% for the 12 month period.
This data is from June 2003 issue of Chemical Engineering.

i try to download the file from http://members.rogers.com/fhcurry/CEIRev3.xls but it just not working. It keeps informed me that the web site does not exist. Actually I'm looking for the cost index (equipment) for 2002, and you said that it could be download from the mentioned website. I've tried so many times but still not there. So, I would like to ask for your kindness to send me this information regarding the cost index to my email address here: zamir_y2k@hotmail.com . That will most appreciated as I really need those information as soon as possible. Thank for your help.

contains an equation trying to fit cost index data from 1950 onwards to a sixth degree polynomial. Come on! This is not good engineering practice for any such set of data.
1. Most of the parameters in that sixth degree equation are not significant
2. A cost or price index curve should be expected to be exponential, rather than polynomial, as this would be the case for a constant growth rate (or rate of inflation in this case).
3. Looking at the data they seem best described by one exponential (i.e. constant rate of inflation) for the years 1950-80, then a new exp curve (reduced inflation rate) for the years thereafter
4. Any model should be tested by its ability to predict. The polynomial predicts a sharp price increase in 2003 and the years ahead. Is that credible? If you just want to interpolate, a simple linear interpolation between adjacent points will do.
A footnote on item 2: I once saw an attempt to fit gas density vs. temperature (constant pressure) by using a high degree polynomial, disregarding the ideal gas law which tells us that including a 1/T term would explain most of the variation (not to mention the work done on equations of state to model deviations from this ideal behavior). Linear regression (aka curve fitting) is a wonderful tool, but a little insight and critical sense are necessary too.

I'm having a little trouble finding relatively recent cost estimation data for a jacketed, glass-lined, stainless steel reactor (stirred). I'd like to estimate the cost for each of several sizes.
Does anyone have any tips?
Much appreciated.
RE: chemical engineering cost estimation
This is a little on the large size, but hopefully there's something out there.
Thanks again.

RE: chemical engineering cost estimation
Seriously, I worked for a major petrochem company 25 years ago, and came up with a survey of suppliers for projection of cost increases into the future. Wasn't very accurate, but it was based on a consistent method.

RE: chemical engineering cost estimation
If you are working in an organization, financial of accounting guys will estimate this for you. When doing an economic analysis of a project, what is normally done is to consider this inflation "forecast" as an allowance. Later, doing a reapprisal (like to see one) of such economic analysis, you will realize that you never thought that the nickel prices are sky-rocketing, or crude oil has turned down (???).
So, it would be an interesting exercise to start such survey of suppliers here. Any suggestion, Larry?
Have a safe day

This is a market place for equipment.
It is sometimes handy to get an "idea" of the price.
