描述
隨著工業(yè)的迅速發(fā)展，氮氣在化工、電子、冶金、食品、機械等領域獲得了廣泛的應用，我國對氮氣的需求量每年以大于8%的速度增加。 氮氣的化學性質不活潑，在尋常的狀態(tài)下表現(xiàn)為很大的惰性，不易與其他物質發(fā)生化學反應。因此，氮氣在冶金工業(yè)、電子工業(yè)、化工工業(yè)中廣泛的用來作為保護氣和密封氣，一般保護氣的純度要求為99.99%，有的要求99.998%以上的高純氮。但是純凈的氮氣無法從自然界直接汲取因此為了更好的提高氮氣在工業(yè)生產(chǎn)的利用率，企業(yè)主要采用空氣分離法?？諝夥蛛x法中包括：深冷法、變壓吸附法(PSA)、膜分離法。下面工采網(wǎng)小編就來簡單介紹一下氧氣分析儀在PSA型制氮機中的相關應用。
