Thermal Characterization of Coal Tar

05/30/2012 12:37 AM

Dear all,

I request you all to provide a spreadsheet for combustion of coal and its it's thermal charaterisation at different temperatures including that of Coal tar.

Thanks in advance,

Govind Rao

Is the information in Perry, "The Chemical Engineer's Handbook" inadequate in some way, then?

Is the information in Kempe's Engineers' Yearbook inadequate in some way, then?

As you said the the Perry's does not give enough of information nor the Kemp. There is a spreadsheet available, which is known as "Combustion Expert". The cost is prohibitive, therefore is not accessible to me. This spreadsheet gives " everything on the earth" about the combustion of coal and gases. However, I am optimistic that somebody might have cast their own spreadsheet and would be kind enough to spare a copy.

I believe that the software that you are interested in is available from a website called "Combustion Software"

www.combustionsoftware.com

The software developer offers it for $1950. The developer is based in Ohio, USA

You are right! but Oops!! look at the cost. In terms of Indian Rupees its nearly twice the amount I earn in a month.

I'm no chemist by any stretch, but have been exposed to a couple of tidbits, which I'll plug-in for the sake of seeing whatever is yet-to-come.

NACE offers some rather extensive training in the inspection of protective coatings, to include coal tar enamels, coal tar epoxies, and coal tar urethanes (etc).

During one of said classes, I recall the instructor commenting that "much work has been done to characterize the exact polymerization that takes place in the curing of these coatings. Said task is nigh-onto *impossible* to achieve, due to the dramatic differences in the exact constituents of various coals/coal tars produced around the globe."

In that same vein (as I've posted elsewhere), when I worked at the General Electric plant in Erie, PA (decades ago) [Google-earth "2901 E Lake Rd, Erie, PA" ... then, drop about 500m south, and you can zoom-in on a nice view of the facility's power-plant stack] , I learned an interesting lesson.

Frequently, the most highly-trained/skilled/edumacated individuals have "primary duties" that you would not expect.

The plant had a chemist on staff (of the PhD type, I vaguely recall) one-of whose principal duties was to validate the testing of the coal that was hauled-in to power the plant. The company paid NOT by the train-car load, nor by the ton ... but rather by the amount of energy that could be expected out of each carload.

The numbers DIFFER , measurably , between each batch extracted from the ground.

So ... it seems to me that your question would require (as you stated) a veritable "spreadsheet" response ... with said spreadsheet being worth a considerable sum.

Or, am I *WAY* off-base, not understanding what you are asking for...?
