Reasons for leakage of ammonia synthesis tower
Thread Content
The ammonia synthesis tower of our factory has a φ14X2 stainless steel pipe installed in the leak detection hole on the outer cylinder surface and connected to the bottle to monitor the synthesis leakage. During the operator's inspection, he found that the bottle was bubbling. He stopped for inspection and used magnetic particle inspection and ultrasonic inspection to find no problems with the weld. What should I do?
Does the ammonia synthesis tower have such a leak detection device? Is LZ talking about the urea synthesis tower? Generally, leak detection is necessary only for equipment with linings. Ammonia synthesis towers generally do not have linings, right? !
1. Analyze the gas composition and confirm that it is synthesis gas. 2. If it is confirmed to be syngas, it must be leaking. 3. I don’t know the specific detection method. I am a craftsman.
Don't understand what it means? Is it monitoring the inner layer of the composite layer for leaks?
What the poster is talking about is a urea synthesis tower. The ammonia synthesis tower has an inner and outer cylinder without a lining. How come there is a leak detection pipe? If a pipe is led out from the outer cylinder, this pipe is high-pressure, and it is not as simple as bubbling. If the poster is talking about a urea synthesis tower, the leak detection tube comes out with steam, and bubbling is normal. Generally, the condensate of the leakage steam is analyzed and detected.
I'm talking about the ammonia synthesis tower. I'm not mistaken. It's mainly used to detect leaks in the outer cylinder! During the production process of the equipment, leakage holes are left on each layer for the user. During multi-layer press molding, if gas leaks from that layer, the gas will come out of the leakage holes and send out an alarm signal, requiring the company to stop for maintenance.
