boiling point 在句中是沸点吗? 方便大家理解，整段文章如下： when liquid-filling the reactor system, precautions should be taken to prevent flashing feed benzene at the bottom of the vessel from mechanically lifting and disrupting the media bed. one precaution is to keep the vessel pressurized with nitrogen above the boiling point of the benzene fill stream. in this case the boiling point of the feed benzene is the benzene column reflux drum pressure (about 460 kpag). the second precaution is to fill at a flowrate significantly lower than the normal vessel feed flowrate. a small-diameter vessel-filling line is provided around the inlet automated isolation valve of each reactor for this purpose. 查看更多
