Leak detection of the urea high-pressure circuit
Thread Content
Could the teachers please discuss the methods used for leak detection on various equipment in the high-pressure section of the urea plant, and what the effectiveness of these methods is?
The links below all provide thorough discussions on the issues mentioned by the original poster, for your reference. http://bbs.hcbbs.com/thread-323257-1-10.html (Methods for leak detection in urea synthesis towers) http://bbs.hcbbs.com/viewthread.php?tid=315524 (Comprehensive review of methods for leak detection in urea synthesis towers) http://bbs.hcbbs.com/viewthread.php?tid=87016 (Selection of leak detection media for urea synthesis towers) http://bbs.hcbbs.com/viewthread.php?tid=73884 (Issues related to leak detection in high-pressure equipment such as urea synthesis towers)
Thank you to the teacher above for providing the materials. What I want to know is about leak detection for the equipment in high-pressure systems other than the synthesis tower, such as high-pressure ammonium methane condensers, high-pressure ammonium methane washers, stripping towers, etc. I’m not aware of any particularly advanced methods for leak detection at the moment
The leak detection methods for high-pressure ammonium methoxide condensers, high-pressure ammonium methoxide washers, and stripping towers can be the same as those used in urea synthesis towers; the principle of leak detection is identical, with no differences at all!
The principle is the same. Our synthesis tower uses online leak detection; if such systems were used for all other high-pressure equipment, the investment would be substantial. Therefore, leak detection tubes for on-site inspection are used instead, and this approach has certain drawbacks. Hence, we are looking for a simpler yet effective method for leak detection.
You make a very good point. So, how much does the investment in online leak detection for your synthesis towers amount to? Which company provides it?
Among the four high-pressure units, it seems that only the urea synthesis tower and the stripping tower require leak testing. Do the high-pressure scrubber and the high-pressure methamine condenser also need leak testing? Do these two devices come with manufacturer leak detection?
Similar to the stripping tower, the heads of the high-pressure washer and high-pressure condenser are subject to leak detection, while there is no such issue with the cylinder bodies.
In other words, high-pressure equipment generally has leak detection holes wherever there is a lining. Right? :lol :lol :lol
