boiling point 在句中是沸点吗? 原帖由 beileim1 于 2009-2-19 15:21 发表 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. 从整段文字看出，在此工艺过程中，要特别防止苯进料时闪蒸，为此采取了两种措施： 1、用氮气保持罐压力在苯进料的沸点以上，此时苯进料的沸点就是苯回流罐的压力——约460kpag 2、用低于正常罐进料的流速来进料，使用了小尺寸的进料线 特别需要注意的是沸点的定义：一定压力和温度下，同时牵涉到压力和温度 查看更多
