How to deal with the leakage in the bottom reboiler of the absorption stabilization column in delayed coking
Is there a venting process for light hydrocarbons before they enter the absorption tower? If so, stop the absorption and stabilization section to carry out emergency repairs!
Leak —> Seal it immediately； Pay attention to the material of the welding rod!
Check where there are leaks; if the flange is leaking, a gasket can be used to seal it, and work should be stopped temporarily until that is done. If it’s just moderately powerful, extract the absorption stabilization. The compressor stopped; the crude gasoline went to the reject stream, while the rich gas was sent to the flare – over time, the production volume decreased. Let the cargo be securely held. There are many treatment methods. There are also many details
A unit in our company also experienced a leak; it was a leak in the tube bundle. However, the conditions at that time did not permit shutting down the system for repairs, so the pressures in the shell and tube layers were adjusted to be roughly equal.
It is about adjusting the pressure in the tube side and the pressure in the shell side to be roughly the same, so that the possibility of internal leakage and cross-contamination is **reduced**. At the same time, we take regular samples to further confirm whether there is cross-contamination of media! (Is there oil in the steam, or water in the oil?)
