【Daily Question No. 282】October 15, 2018: Briefly describe how the liquid level in a high-pressure separator is controlled What are the effects of excessive fluctuations in the liquid level of the high-pressure separator on the system? The liquid level in the high-pressure separator is controlled by adjusting the amount of oil transferred to the low-pressure separator. An excessively high liquid level in the high-pressure separator can cause the circulating hydrogen to contain oil, affecting the proper operation of the circulating hydrogen desulfurization tower and the circulating hydrogen compressor. An excessively low liquid level can lead to severe gas entrainment in the low-cut oil stream, and may even cause an accident where high pressure mixes with low pressure. (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.

The liquid level is controlled by the amount discharged to the lower level. Fluctuations in liquid level can lead to unstable system pressure and fluctuations in the feed rate to the distillation section; in severe cases, this can result in substandard products

Under normal circumstances, it is done through a level control valve; in special cases, the amount of high-pressure feed also needs to be taken into account. The liquid level is too high, causing the gas phase to carry liquid with it; for example, if the temperature is high, this liquid will be carried to the circulation pump ； The liquid level is too low, resulting in insufficient liquid sealing, which can easily lead to pressure leakage.
