This post was last edited by 955559 on 2017-7-21 22:27. [Q&A Question No. 088] What are the precautions for liquid removal from the diesel hydrogenation KO tank on 2017.03.29? The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 1. Continuous liquid removal is not allowed. 2. The opening degree of the liquid removal valve should not be too large, to prevent excessive leakage of the primary sealing gas at this point, which could cause fluctuations in the flow rate of the primary sealing gas and thus affect the operation of the hydrogen circulation machine. 2017 Q&A Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates have begun) http://bbs.hcbbs.com/thread-1657794-1-1.html 2016 Q&A Summary Thread (updates completed) http://bbs.hcbbs.com/thread-1597792-1-1.html Third Phase of Haichuan’s Outstanding Management Members Selection Contest http://bbs.hcbbs.com/thread-1655902-1-1.html (Source: Haichuan Chemicals Forum)
1. Liquid removal cannot be carried out continuously. 2. The opening degree of the liquid removal valve must not be too large, to prevent excessive leakage of the primary sealing gas at this point, which could cause fluctuations in the flow rate of the primary sealing gas and thus affect the operating conditions of the hydrogen circulation machine.
1. Continuous liquid removal is not allowed. 2. The opening degree of the liquid removal valve should not be too large, to prevent excessive leakage of the main sealing gas at this point, which could cause fluctuations in the flow rate of the main sealing gas and thus affect the operating conditions of the hydrogen circulation machine.
1. Continuous liquid removal is not allowed； 2. The opening degree of the liquid removal valve should not be too large, to prevent excessive leakage of the main sealing gas at this point, which could cause fluctuations in the flow rate of the main sealing gas and thus affect the operating conditions of the hydrogen circulation machine.
1) The liquid level in the KO separation tank; an excessively high level can cause liquid to enter the main sealing gas； 2) Differential pressure between primary seal gas and secondary seal gas filters ； 3) KO decanter differential pressure.

1. Use a walkie-talkie to communicate with the operator inside during liquid removal. 2. Use explosion-proof copper F wrenches. 3. When removing liquid, open the liquid removal valve slowly; do not open it fully. If you hear air flowing in the pipes, close the liquid removal valve
