上海炼油厂常減压蒸餾裝置于1954年6月建成,同年7月試运轉8月正式投入生产。流程如图1所示. 由于原設計存在下列缺点,給生产上带來了相当多的困难: (1)常压塔线速設計为0.98公尺/秒而該塔塔盘距为0.61公尺。因选用綫度太大,造成餾分重叠,油品分割不清; (2)常压塔頂汽油—原油换热器計算錯誤,换热量約少50万仟卡/时,这一部分热量,必須从常压
Shanghai refinery atmospheric vacuum distillation unit was completed in June 1954, the same year in July test run officially put into production in August. The process shown in Figure 1. As the original design of the following shortcomings, to produce a considerable number of difficulties: (1) atmospheric pressure tower line design is 0.98 meters / second while the tower tray distance of 0.61 meters . (2) Atmospheric overhead petrol - crude oil heat exchanger calculation error, heat exchange capacity of less than 500,000 kcal / h, this part of the heat must be From atmospheric pressure
