| 摘 要： | 丙烯是一种受热易气化、受压易液化的常用石油气。卸丙烯罐车最简便的方法有３种，泵卸车、加热升压卸车和利用氮气加压卸车。由于这３种卸车方法各存在不同的缺点，如，丙需大量放空、常温下无法卸尽、高温时无法卸车、升压罐难以补料以及消耗价昂的氮气等，所以在实际操作中一般不单独采取某一种方法，而是采用第一与第二种或第一与第三种结合的方法，其中第一与第二种结合的方法具有投资少、应用范围广、卸车工艺成熟等优点。此方

| Abstract: | Propylene,the common petroleum gas,is subject to gasification under heating and liquification under pressure. Three simple ways are available to unload a propylene tanker;by pump,heating and pressurizing, or pressurizing by nitrogen. Unloading operation is seldom acomplished only by one of the three ways,because each has its operational limitations, such as heavy blowdown, unable to unload out at atmospheric temperature and unable to unload at high temperature,difficult to replenish the pressurizing tank,as well as nitrogen consumption,thus,the first way and second way or the first way combined with the third way are adopted, in which the former way has the advantages of fewer investment, wide operational range and perfect unloading process,and the way has proved itself to be high economical benefits to unloading operation for modified propylene tanker in Fushun Acrylic Fibre Factory. |
