延安石油化工廠聚丙烯裝置每年排放尾氣約4800噸，其中含有80%的丙烯成分。目前這部分尾氣被作為燃燒氣燃燒，造成能源的極大浪費(fèi)，同時(shí)導(dǎo)致丙烯單耗一直居高不下。為了最大限度提高能源利用率，將尾氣變廢為寶，該廠對多種工藝方案進(jìn)行分析和綜合對比，最終確定采取冷凝工藝技術(shù)對聚丙烯裝置尾氣進(jìn)行回收利用。
延安石油化工廠聚丙烯裝置尾氣改造項(xiàng)目正式開建。該項(xiàng)目建成后可顯著降低聚丙烯裝置丙烯單耗，預(yù)計(jì)一年可從尾氣中回收近4000噸丙烯(95%)，若按丙烯每噸價(jià)格8000元計(jì)，每年可創(chuàng)經(jīng)濟(jì)效益近2000萬元。項(xiàng)目預(yù)計(jì)于明年1月完成建設(shè)。
