[Daily Question No. 208] 2018.08.02: The key components related to the transfer of pressure from high pressure to low pressure in a hydrogenation unit are ( ). Multiple choice: A. An excessively low high-pressure liquid level leading to pressure transfer； B. The feed pump is prone to pressure cross-talk during startup and shutdown ； C. Excessive hydrogen circulation flow can lead to pressure cross-talk ； D. During the start-up and shutdown of the new hydrogen machine, a direct connection between the primary and secondary circuits can easily lead to voltage crossover.
