Propylene, a kind of petroleum gas easy to liquify or gasify under pressure or heat, can be transported as liquid depending on the gaseous pressure in tank. In Fushun where spherical tank is required to have an operation pressure ranging from 0. 9 to 1. 4Mpa, the boosting system for liquified propylene tank must be started to pressurize when temperature drops to 11C or less. The original boosting system has the following drawbacks; ①There is one booster for each tank; since no standby booster is available, continuous propylene transportation can not be guaranteed; ②The three boosters for three tanks require excessive heating steam to prevent frosting in winter; ③The fact that both liquid and gas pipes for booster have only one valve makes it difficult to repare any fault booster. The modified boosting system now consists of two boosters, with only one running for the three tanks for normal operation, thus steam consumption is reduced. Attention shall be paid to the following points in order to realize better economic benefit:①Modification should be carried out during the performance of tank overhaul,②Valves should pass strict pressure test,③Qualified welding shall be achieved for the pipeing in boosting system.

丙烯是一种受压易液化、受热易气化的石油气,在储运中依靠储罐气相压力完成丙烯的液相输送。对抚顺地区,储罐操作压力要求在0.9~1.4MPa之间,当气温低于11℃时压力降低,必须启动液化丙烯储罐的升压系统进行升压。原丙烯球形储罐每个升压系统只有一台升压器,无备用的,不利于液化丙烯物料的连续输送。由于3台升压器全部投用,冬季需要消耗大量蒸汽加热防冻,而且升压器的液相和气相管道只有一道阀,使升压器无法检修。改造后的升压器系统采用一备一用,正常生产时投入一台升压器,就能给3个球形储罐同时升压,降低了蒸汽消耗量。同时改造施工要选在储罐大修期间进行,阀门要经过严格的打压试验,确保升压系统管道的焊接质量,方可提高经济效益。
