【Daily Question No. 330】December 02, 2018: What is the function of each vent valve on the compressors in a hydrogenation unit? ⑴Before starting the compressor, nitrogen and hydrogen are purged and vented. ⑵During shutdown, the compressor is depressurized to –; emergency depressurization occurs when the compressor operating under 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.

⑴Before starting the compressor, nitrogen and hydrogen are purged and vented. ⑵During shutdown, the compressor is depressurized to the flare. Emergency depressurization occurs when the compressor operates under overpressure.
⑴Before starting the compressor, nitrogen and hydrogen are purged and vented. ⑵During shutdown, the compressor is depressurized to the flare; emergency depressurization occurs when the compressor operates under overpressure.
Before startup, and after shutdown, it serves as a vent for system replacement to the flare. It serves as a protection during startup to prevent the unit from experiencing overpressure.
1. Nitrogen and hydrogen displacement 2. Pressure release to the flare 3. Emergency pressure relief
The main filling chamber should have air leakage and nitrogen venting, while the oil seal side should have nitrogen isolation gas venting
