【Q&A Question 205】July 30, 2018: Briefly describe how to properly operate the reflux drum in a distillation tower ①Maintain stable pressure in the reflux tank to ensure stability of the pressure at the top of the distillation tower ； ②Control the liquid level in the reflux tank carefully; an excessively high level can cause fuel gas to contain oil, while an excessively low level can lead to the reflux pump running dry ； ③Control the level in the reflux tank properly; if the level is too high, water will be carried back with the reflux, while if the level is too low, oil will be carried in with the wastewater. (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.

①Maintain stable pressure in the reflux tank to ensure stability of the pressure at the top of the distillation tower； ②Control the liquid level in the reflux tank carefully; an excessively high level can cause fuel gas to contain oil, while an excessively low level can lead to the reflux pump running dry ； ③Control the level in the reflux tank properly; if the level is too high, water will be carried back with the reflux, while if the level is too low, oil will be carried in with the wastewater.
1. Ensure proper pressure control to maintain stable tower pressure. 2. Maintain proper liquid level control to prevent oil contamination in the gas phase when the liquid level is too high, or pump cavitation when the liquid level is too low. 3. Control the interface level properly to prevent oil contamination in acidic water and water contamination in the reflux pump
(1) Control the operation of the rich gas compressor to ensure stable pressure at the top of the distillation tower. (2) Control the liquid level in the reflux tank properly; an excessively high liquid level can cause liquid to enter the inlet of the rich gas compressor, while an excessively low liquid level can lead to the vacuuming effect caused by the reflux pump. (3) Control the interface of the reflux tank properly; if the interface is too high, it will cause water to be carried back with the reflux, while if it is too low, oil will be carried in the wastewater.

1. Maintain stable pressure in the reflux tank to ensure stability of the pressure at the top of the distillation tower. 2. Control the level of the reflux liquid properly; if the level is too high, it can cause fuel gas to contain oil, while if the level is too low, it can lead to the reflux pump running dry. 3. Control the interface of the reflux tank properly; an excessively high interface causes water to be carried back with the reflux, while an excessively low interface results in oil being carried in the wastewater.
