About the translation of TCR/MCR/LCR LOOP in oil refining
Thread Content
I saw CDU TCR LOOP/CDU MCR LOOP/CDU LCR LOOP in the information. I wonder what these three TCR/MCR/LCR mean?
FYI. CDU control display unit TCR temperature coefficient of resistance MCR magnetically controlled reactor LCR liquid core pressure
In oil refining, CDU should be crude oil distillation unit, right? How to translate the other abbreviations?
As a non-professional, can you give me more information? FYI: MCR-Mid Circulating Reflux, LCR-Low Circulating Reflux
These words are mentioned in the information, but I don’t know what they refer to specifically.
There are several refluxes in normal and vacuum operation, TCR, MCR, LCR. What do they mean specifically? Thank you!
My search method: 1. It is known that these abbreviations are about reflux, so R must stand for reflux. Just enter "TCR, MCR, LCR reflux" into Google to search. http://www.google.cn/search?hl=zh-CN&q=TCR%E3%80%81MCR%E3%80%81LCR++reflux+&btnG=Google+%E6%90%9C%E7%B4%A2&meta=lr%3D&aq=f&oq= Article 7 is ； 2. If you want to locate more accurately and quickly, then enter the crude unit of the atmospheric pressure device-----"TCR, MCR, LCR reflux crude unit" to search. The first result is: http://www.google.cn/search?hl=zh-CN&q=TCR%E3%80%81MCR%E3%80%81LCR++reflux+++crude+unit+&btnG=Google+%E6%90%9C%E7%B4%A2&meta=lr%3D&aq=f&oq= (This website is very useful. I have saved it. I can also find treasures in the process of helping others! ) LCR, Lower Circulation Reflux MCR, Middle Circulation Reflux TCR, Top Circulation Reflux. The Chinese are "bottom reflux/middle reflux/top reflux" respectively.”
CDU=crude distillation unit normal pressure tower is more accurately called as follows: TCR top circulation reflux MCR middle circulation reflux LCR bottom circulation reflux
Because there are generally only "tower top reflux" and "middle section reflux" in atmospheric and vacuum units. The bottom of the tower is heavy residual oil and does not reflux. In addition, lower is not equal to bottom. It is considered that the three words Top, Middle, and Lower are only distinguished from their relative positions and are processed as: Top circulation reflux/middle circulation reflux/lower circulation reflux, these expressions can be found online.
