【摘要】 根据高压氢化工艺要求 ,以W型往复式真空泵为基本机体 ,改制成氢气循环机。这种循环机能使氢气不断通入氢化反应塔中 ,鼓泡搅拌 ,使催化剂、氢气和反应液三相均匀接触 ,完成氢化反应过程。经多年生产运行表明 ,该循环机用于松香腈高压氢化工艺 ,安全可靠、运行状况良好。节省投资 10余万元更多还原

【Abstract】 A hydrogen recirculating machine was designed from a W Recirculating Vacunm pump. With this method the hydrogen can inter into the hydrogenation column for bubbling and mixing so as the catalyst, hydrogen and reaction liquor may contact evenly to complete the reaction process. The results of application for years show that the machine can be used successfully for rosin nitrile hydrogenation process, saving more than 100,000 yuan of capitals.更多还原
