When the heat exchange tube ruptures, which fluid is released: the fluid on the tube side or that on the shell side?
Thread Content
In the water cooler of an ammonia synthesis plant, the shell side is filled with circulating water, while the tube side contains syngas. The design pressure on the shell side (the low-pressure side) is less than 2/3 (or 10/13) of the design pressure on the tube side (the high-pressure side). A safety valve is installed on the shell. I would like to know what medium will be released in the event of a rupture in the heat exchange tubes, and how this can be calculated. I seek advice from those with expertise in this area.
It should be the medium on the high-pressure side.
The material on the high-pressure side is released to the low-pressure side; you should calculate the medium based on the material in the pipeline. Personal advice
A safety valve is installed at the top of the shell, and its setting value is determined based on a multiple of the maximum allowable water pressure. This should be reasonable, for reference.
Does syngas not dissolve in circulating water?
