The recovery of atmospheric light oil yield of atmospheric in the northern atmospheric distillation tower of shenghua teaching & test factory , science and technology group of china university of petroleum has been increase by about 4 or 5 percent through the following methods : changing the tray perforation of atmospheric tower , adjusting the amount of stripping steam and the outlet temperature of the atmospheric heater and merging atmospheric excess vapor into 3rd atmospheric drawn - stream to keep the fractions content of bottom oil below 5 % before 350
摘要中国石油大学科技集团胜华教学实验厂北常减压蒸馏装置换炼胜利管输油后，通过改变常压塔塔盘开孔率、调节常压塔汽提蒸汽量和常压炉出口温度、常压过汽化油并入常三抽出线等措施，控制常压塔底油350前馏分含量小于5 % ，使常压轻质油收率提高约4 % ~ 5 % 。
