【Q&A Question 266】September 29, 2018: Briefly describe the hazards of an excessively low level in the cold high-pressure liquid level gauge If the high-pressure liquid level is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations at the low-pressure side or even overpressure. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Correct: 3 wealth, Incorrect: 1 wealth ； Mass posting of posts – rated based on the lowest score ； Replies that are unrelated to the answer are considered spam and will be deleted immediately.

If the high-pressure liquid level is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations at the low-pressure side or even overpressure.
High voltage connected to low voltage, causing an explosion in the low-voltage circuit
If the high-pressure liquid level is too low, it can easily lead to high pressure leaking into the low pressure area; moreover, the three-phase separation within the high-pressure section is not proper
If the high-pressure liquid level is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations at the low-pressure side or even overpressure.
An excessively low high-level liquid level can cause high pressure downstream to leak into the low-pressure area
If the high-pressure liquid level is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations at the low-pressure side or even overpressure
If the liquid level in the cold high-pressure section is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations or even overpressure in the cold low-pressure section； The pressure in the reaction system dropped suddenly, and the outlet pipeline vibrated intensely ； The feed rate to the distillation column surged, causing the pressure and liquid level in the column to rise suddenly.
If the high-pressure liquid level is too low, gas can be entrained downstream due to insufficient liquid sealing, resulting in pressure fluctuations at the low-pressure side or even overpressure.
