【Daily Question No. 279】October 12, 2018: Briefly describe the function of a high-temperature separator. The main role of such a separator is to separate gas, liquid, oil, and water, thereby preventing oil from entering the recycle hydrogen compressor and causing accidents. (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 cooled reaction effluent is subjected to gas-liquid separation
Separate the recycled hydrogen, acidic water, and reaction products
It is mainly the three-phase separation of gas, water, and oil
(1) Ensure residence time. (2) Perform gas-liquid and oil-water separation. (3) The foam breaker prevents liquid from entering the compressor. (4) Ensure oil-water separation and maintain a certain height at the oil outlet.

The high pressure is primarily used for separating gas, liquid, oil, and water, thereby preventing accidents caused by oil entering the circulating hydrogen compressor.

The operating temperature for cold high-pressure processes is generally between 40 and 50°C. An excessively high operating temperature is not conducive to the desulfurization of circulating hydrogen; it can also cause hydrocarbons to be carried along, leading to foaming of the amine solution. In severe cases, liquid can be carried in the circulating hydrogen, affecting the safe operation of the hydrogen circulation unit. Three-phase separation of gas, oil, and water takes place in the cold high-pressure section; the gas from this section is sent to the inlet of the recycle hydrogen compressor for reuse after desulfurization. At least two safety valves are typically installed at the top of the cold high-pressure section. The cold high-sulfate acidic water is sent to the wastewater treatment unit together with the acidic water separated from the cold low-sulfate water. The cold high-boiling-point oil is sent to the cold low-boiling-point section for further separation.
