Considering the geological structure of the cooled lake on which the oil refinery was built,and less viberation and less noise of static pressure pile and no infleunce on the neighbour refinery units during construction,the static pressure pile was used for the extention of a atmospheric and a vaccum distallation unit in Shanghai Oil Refinery in 1972.The type Djg-80pile driver has 800KS axil static pressure. This article introduces the basic design and determination of pile bearing capacity.The maximum sinking of the foundation of No.2tower is 14.85cm.The minimum sinking of the foundation of cold exchange frame is 5.1 cm.The foundation of cylindrical furnace inclines by 2.5 per cent,the vacuum tower inclines by 1.86 per cent.Both value are below the spe- cified ones.Now such units are running normally.Using The method of static pressure pile don't infleunce not only on the structure of units itself,but also on the neighbour structures. The method can save 26 percent of concrete,40 per cent of steel,25 per cent of enginee- ring cost as compared with the method of driving pile.So the author suggests it can be used in any places where the suitble conditions exist.

上海炼油厂在厂区内扩建常减压装置时,考虑该装置座落在回填土冷却湖上的地质概况及静压桩具有振动和噪音较小特点,不影响邻近装置的安全。在1972年扩建施工中采用了静压桩的方法,其采用的静力压桩设备 Dig—80型,最大轴向静压力为800kN。文章介绍了该法施工中的基础设计与桩承载力的确定;采用静力压桩的构筑物基础,经9~12年的基础沉降观测,看出基础最大沉降为14.85cm(减压塔_2),最小沉降为5.1cm(冷换框架),实测圆筒炉基础倾斜为2.5‰,减压塔_1为1.86‰,倾斜小于规定。经过实践验证,设备使用完全正常,静力压桩不仅对本装置的构筑物无影响,对邻近构筑物也无影响。工程费用比打入桩节省混凝土26%、钢材40%,降低工程造价25%。笔者认为有条件的地方,可以推广使用静压桩。

Heat coils made of austenitic stainless steels were installed in fluidized bed of an actifier of catalytic cracker installation in an oil refinery unit. Steam—water mixture circulated within the coils with high pressure. Corrosion fatigue failure occurred in the coils in about 40 days after commissioning of the unit. In the present paper, corrosion fatigue phenomenon of austenitic stainless steels in high temperature,high pressure water was discussed in the real engineering condition. It was indicated that the lifetime of the coils could be largely increased by improving the steamwater flow condition.

分析表明炼油厂催化裂化装置再生器取热盘管失效的主要原因是腐蚀疲劳。本文就该实际工程条件下,对1Cr18Ni9Ti及1Cr25Ni20两类奥氏体不锈钢在高温含微量氯离子水中的腐蚀疲劳现象及成因进行了讨论。改善汽水流动条件可显著延长盘管的使用寿命。

Major points which should be considered in establishing a computer optimization sys-tem for refinery production and management and in optimal control of refinery unit operation are dis-cussed.
