Regarding the structure of vertical cold high-pressure separators
Thread Content
Regarding the vertical cold high-pressure separator structure of hydrocracking units, since there is no water pocket, how is the level measured? If the pressure level is lost, will high pressure flow into low pressure? Will the oil still leak into the acidic water tank? It would be better if there were images; thank you all.
The vertical cold high-pressure separator structure in hydrocracking units refers to a technical solution in which a vertical cold high-pressure separator is used for separation and distillation within such units. For this structure, since there are no water pockets, another method is usually employed to measure the interfacial potential, namely by calculating it using pressure and temperature. If the interface level disappears, oil from the high-pressure area will be forced to enter the low-pressure area, resulting in a change in the liquid level. However, due to the presence of multiple storage tanks in the hydrocracking unit, this liquid may be transported to other locations rather than flowing directly into the acidic water tank. For specific structural diagrams, reference can be made to relevant documents such as the Hydrocracking Unit Design Manual. .
Okay, thank you. If the level indicator disappears, there is no risk of high pressure affecting low pressure for the time being, but it will cause the liquid level to drop too low. Then, is there a link to these drawings?
