【Q&A Question 081】March 22, 2018: Briefly explain what level the high-level liquid level is generally kept at? Why is the high-level liquid level controlled by adjusting from high to low volume? The liquid level is generally maintained at 50±5%. If the liquid level is too high, excessive liquid will be carried by the circulating hydrogen, which can cause damage to the compressor; if the liquid level is too low, it can lead to an accident where high pressure mixes with low pressure. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

The high-level liquid level is controlled by adjusting the flow from the high level to the low level. The liquid level is generally maintained at 50±5%. If the liquid level is too high, excessive liquid will be carried by the circulating hydrogen, which can cause damage to the compressor; if the liquid level is too low, it can lead to an accident where high pressure mixes with low pressure.
The high-level liquid level is controlled by adjusting the flow from the high level to the low level. The liquid level is generally controlled at 50±5%. If the liquid level is too high, significant liquid entrainment in the circulating hydrogen can occur, which may cause damage to the compressor.
The high-level liquid level is controlled by adjusting the flow from the high-pressure side to the low-pressure side. The liquid level is generally maintained at 50±5%. If the liquid level is too high, circulating hydrogen will carry liquid with it, which can cause damage to the compressor; if the liquid level is too low, high pressure may be transmitted to the low-pressure side.
The high-level liquid level is controlled by adjusting the flow from the high level to the low level. The liquid level is generally kept at around 50%; if the liquid level is too high, significant liquid will be carried along with the circulating hydrogen, which can easily cause damage to the compressor.
30~70%, facilitating hydrogen release and the liquefaction of other substances
Answer: The high-level liquid level is controlled by adjusting the flow from the high level to the low level. The liquid level is generally maintained at 50±5%. If the liquid level is too high, excessive liquid will be carried by the circulating hydrogen, which can cause damage to the compressor; if the liquid level is too low, it can lead to an accident where high pressure mixes with low pressure.
The liquid level of the hot high fraction and that of the cold high fraction are controlled at 50–60%. Lowering the liquid level control for the cold high-pressure section is intended to prevent liquid from entering the compressor. An excessively high liquid level in the high-pressure separator poses a threat to the safety of the recycle hydrogen compressor. If the liquid level in the high-pressure section is too low, high-pressure gas can enter the low-pressure separator, leading to serious accidents.
30-70%； To prevent high voltage from leaking into low voltage.
The high-level liquid level is controlled by adjusting the flow from the high-pressure side to the low-pressure side. The liquid level is generally maintained at 50±5%. If the liquid level is too high, circulating hydrogen will contain a large amount of liquid, which can cause damage to the compressor; if the liquid level is too low, it can lead to accidents where high pressure mixes with low pressure.
