设置氮封,污油罐微正压操作,油气回收。

现在这个属于标配,必须装,而且即使就地放空还必须设置油气过滤措施才可以!

污油罐一般没有压力,放空管线是常开的,一般采用高出周围建构筑物、平台2m以上,

虽然污油罐是连通火炬罐的,但是因为油气分压和火炬背压的问题,往污油罐倒油还是很难倒,我们之前的装置就遇到这样的问题。解决方法:在污油罐放空线手阀前加三通,引出一根管线,加一道手阀,加管道泵,管道泵进口设置倒油的漏斗,漏斗下装一道手阀,倒油的时候把管道泵打开。这样可以解决倒油的问题,但是也带来另一个问题,倒油的时候油气味道比较大,现场油滋滋的。

1)会有压力。原因是:介质会携带少量的气体,油品挥发;2)可以倒进去;3)放空管设置自动排放阀就可以;4)最好连接油气回收装置。
