Increase the high-pressure temperature B. Lower the high-pressure liquid level C. Raise the high-pressure interface level D. Increase the high-pressure liquid level. The reference answers will be visible after recovery; scoring is possible by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Note: For questions of the type \"one question per day,\" if someone replies continuously for a month, that is, more than 30 posts, their score will be assigned as 2 points, which is the lowest possible score. Click once to reply; if multiple replies are made, points will be awarded as appropriate, as deleting posts is also a waste of time. C scoring criteria: 2 Wealth points for incorrect attempts; *incomplete* answers score 3–8 points. 10 Wealth points are awarded for correct answers, along with a detailed explanation; those who provide a correct answer but incomplete details receive 15–20 Wealth points. Please use these criteria for scoring. Note: If there are editing records after answering, only those who participated will be given points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters unrelated to the answer are all considered malicious spamming; points will start to be deducted after three warnings. 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 Petrochemical Sector – “Creative Ideas for Energy Savings” Campaign (Phase 2 is in full swing) http://bbs.hcbbs.com/thread-1666758-1-1.html 2017 Coal Chemicals – “My Technical Upgrades” http://bbs.hcbbs.com/thread-1786290-1-1.html
