Compressor Curves are generally misunderstood in day-today working of process engineers and many confusions arises out of discussion among cross functional teams. This becomes more confusing in case of Recycle loop systems for example in Ammonia synthesis loop OR Ethylene oxide Synthesis Loop.

Oil Tanks - Tonnage Measurement - New Cost Effective Method
technologist | 11 Nov, 2007, 20:52 | Cooling Towers | (362 Reads)

Recently Zaki had posted a write up on his blog related to this issue, whereas I commented about inaccuracy of this method & my experience. I had been doing it in my earlier days but I was never satisfied with the results due to large inaccuracies. So I thought to share it with you which will help you in taking care of these aspects.

One may not think or consider an inaccuracy of 0.5-2.5 % seriously but the view can be made clear from a simple example in case of tanker of etiher diesel or fuel oil. The tankers usually do not have more than 2 meter in height. If you dip tape & measure where an error of <1" than you have an error of 0.5% (10mm / 2000mm which is tank height)to 1.2%.

This post is a part of an ongoing updates on this site to keep you aware about developments & future planning.

I am adding DOWNLOADS section, which will provide useful downloads for all of you. Kindly feel free to browse it here OR select it from tab listed at the top of this page. You will find only those which I have used and found them useful for all.

Next I have removed Stores page, which shall be modified & relaunched by next month or so.

Next based on site stats I am finding that many of my readers are searching for cooling tower related queries. So I would request them to post their any kind of query related to Cooling Towers on my FORUM & I will answer them one by one including evaluations of performance, tower capacity related questions or anything else.

I am also including one GuestBook on downloads page & request readers to leave their feedback so that I can further improve this site.
Now You can subscribe by FeedBlitz also.

Many forums or dicussion board / Blogs will tell you about the role of process engineers in the chemical manufacturing industry. But you may rarely find out the real technical challenges faced by a process engineer. Recently I faced some of them & then thought to write on this issue.

The most important out of several ones is the availability of CORRECT DATA.
