技術(shù)工藝路線可以適應(yīng)國(guó)內(nèi)主要原材料特性，技術(shù)工藝路線簡(jiǎn)單明了，利于流程控制和設(shè)備操作 。 技改后 位于該區(qū)域內(nèi)的 設(shè)備均 采用電氣防爆設(shè)備， 電線穿鋼管暗敷。在天然氣重整生產(chǎn)甲醇、乙烯、丙烯氧化生產(chǎn)其氧化物，脫硫及回收時(shí)，也均需要消耗大量氧氣。具有變形小，油銹敏感性低、抗裂、致密性好等優(yōu)點(diǎn)，為許多制造企業(yè)廠家所采用如造船業(yè)、工程焊接氣體保護(hù)等。 近年來(lái)，隨著空分設(shè)備制造技術(shù)的發(fā)展，我國(guó)的氣體分離裝置（設(shè)備）得到迅猛發(fā)展，一 大批 600m179?；瘜W(xué)性質(zhì)很活潑，能發(fā)生氧化、聚合及金屬取代等反應(yīng)。 （ 3）改造后的 項(xiàng)目廠房、設(shè)備 煥然一新， 能提升企業(yè)形象，產(chǎn)生更好的
