The cause of the high pressure difference in the ammonia synthesis tower has been identified. After disassembling the internal components, it was found that the upper part of the entire circumference on the outside of the radial baskets in the third section (the gas outlet side) was cracked, which allowed catalyst to leak into the tube sheet of the upper heat exchanger, resulting in blockages and thus a high pressure difference in the tower.
That’s great! It’s necessary to find out the cause of the cracks; otherwise, more problems will arise.

It’s hard to say which manufacturer’s components are problematic; it’s mainly related to manufacturing issues – heat stress concentration, and insufficient expansion of the radial ring tubes, which leads to tearing.
Operating without pressure is mainly due to thermal stress; the force involved is quite significant
