In the design, normal pressure distillation tower was selected in 1.2million t/a hydrocracker fractiontor units. Engler distillation data of fractionating tower is mainly designed for the distillation data of hydrocracking unit product oil TBP and products, calculation of material properties of the product, determine the cutting scheme, calculation of the yield of the product. The main contents are: the design of tower plate form,the diameter of the colum, tray spacing, height determination. The tower plate type float valve tower was determined ultimately, the tower diamer is 3.2m, plate spacing 0.8m, tower 34.63m. The basic scheme of the design is: the two side of fractionating tower, the fractionator top producing naphtha, two sides are producing heavy naphtha, kerosene,the bottom of the tower of tail oil (ethylene raw material). The design parameters of the selected to meet the relevant provision of, can satisfy the operating flexibility in certain productin range. Key words: light oil; hydrocracking; fractionator; valve tray?  目 录 摘要 I ABSTRACT II 绪论 1 1.1油的概述 1 1.1.1油的用途 1 2 1.2
