各位,有没有内压缩带粗氩塔流程的,平时粗氩塔投用没?粗氩塔的投用对整个系统有没有实质性的影响?我们准备将粗氩塔从系统隔开,彻底不投粗氩塔?

多大的空分?可以不投粗氩塔。

15000,关键是对氧气纯度有影响没?!看资料上说,不抽氩馏分的,得不到双高产品。

说实话我也打算这么干,不过我们的是4500的外压缩

当然不行,想想在投氩塔时如果长时间不产液氩,也不放空氧的纯度是降低的,一般来说粗氩气占进塔空气总量的21%左右,这么大气量留在上塔,不投用必然导致氧纯度降低

高负荷工况下,氧纯度降的到好多,有没有这方面的经验数据?

这个粗氩不投用可以,但是氧纯度要降低,注意把氮产量适当提高,要不容易氮塞,具体你可以慢慢加负荷试验

我们的是120000的,以前没生产液氩现在有。一样都还是生产高纯度液氮液氧。

氩系统都隔绝了还会发生氮塞?
Reply #102019-04-27
可以不投,但氧纯度会低点,氧量也拉不出来,后系统用氧少还可以,能耗高了

当然不行,除非你能做到把粗氩气持续有控制的排掉,想想氩塔投用时的情景就知一二
