Can the condensate be used to speed up ammonia removal after the ammonia permeation leak test is completed?
Thread Content
After the ammonia leak detection using high-pressure urea equipment is completed, the standard procedure is to first vent the ammonia, and then replace the space with nitrogen repeatedly until it meets the required standards. Here is a question: can condensate be added during the ammonia discharge process to speed up the discharge?
Disadvantages of using condensate: 1. Ammonia gas has a high solubility in condensate, which can create local vacuums and pressure imbalances, leading to damage to the tank. 2. When ammonia dissolves in water, it releases a large amount of heat, causing a temperature imbalance that leads to stress damage to the equipment. It is best to replace it with nitrogen, as it is safer.
Why is it necessary to speed up ammonia discharge? Is it really essential to discharge ammonia quickly?!
It is best to avoid using cold liquid; the accident that occurred in the urea synthesis tower in Pingyin, Shandong, was related to cold liquid. Additionally, helium testing is the best method for detecting leaks these days.
