【Q&A Question 108】April 18, 2017: What should the operator pay attention to when the new hydrogen compressor is operated under variable load conditions? The reference answer can be seen after responding; points will be awarded for identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) When the new hydrogen compressor is operated with variable load, the operator must pay attention to adjusting the pressure at each stage of the compressor in order to prevent an excessively high compression ratio. At the same time, it is necessary to regulate the outlet flow rate of the compressor to avoid fluctuations in the pressure of the high-pressure stream. Scoring criteria: 2 Wealth points for incorrect responses; *incomplete* answers earn 3–8 points. 10 Wealth points are given for correct answers accompanied by detailed explanations; responses that are correct but lack sufficient details earn 15–20 Wealth points. Please score according to these criteria. 2017 Q&A Summary Thread (updates starting now) http://bbs.hcbbs.com/thread-1657793-1-1.html 2017 Daily Question Summary Thread (updates starting now) 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 (sponsors sought; highest returns ever) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event organizer.

Pay attention to changes in hydrogen volume, system pressure, pressure ratio adjustments, bearing temperature changes, and current variations; pay attention to system pressure! Changes in exhaust temperature!
Pay attention to adjusting the pressure at each stage of the new hydrogen compressor to prevent an excessively high compression ratio; at the same time, ensure proper adjustment of the outlet flow rate of the new hydrogen compressor to avoid fluctuations in pressure.
When the new hydrogen compressor is operated under variable load conditions, the operator must pay attention to adjusting the pressure at each stage of the compressor in order to prevent an excessively high compression ratio. At the same time, it is necessary to regulate the flow rate at the compressor outlet to avoid fluctuations in high-pressure levels.
Pay attention to adjusting the pressure at various stages of the new hydrogen machine to prevent an excessively high compression ratio, and also pay attention to regulating the outlet flow rate of the new hydrogen machine to avoid fluctuations in high-pressure levels.
When the new hydrogen compressor is operated under variable load conditions, the operator must pay attention to adjusting the pressure at each stage of the compressor in order to prevent an excessively high compression ratio. At the same time, it is necessary to regulate the outlet flow rate of the compressor to avoid fluctuations in the pressure of the high-pressure stream.
Pay attention to export pressure, lubricating oil pressure, temperature of each valve, and exit temperature; adjust the inlet and outlet cross-connections as appropriate, as well as the flow rate of the medium at the exit
Pay attention to export pressure, lubricating oil pressure, temperature of each valve, and exit temperature; adjust the inlet and outlet cross-connections as appropriate, as well as the flow rate of the medium at the exit
Control the temperature and pressure of the reactor, adjust the feed rate
Pay attention to pressures at all levels, exhaust temperature, and valve temperature
When the new hydrogen compressor is operated with variable load, the operator must pay attention to adjusting the pressure at each stage of the compressor in order to prevent an excessively high compression ratio. At the same time, it is necessary to regulate the outlet flow rate of the compressor to avoid any changes in the pressure of the high-pressure stream.
