2017年以來，遼陽石化開展技術攻關，研究消除環(huán)氧乙烷/乙二醇裝置瓶頸的方法。2018年，遼陽石化工程技術人員對裝置進行全面排查摸底和分析，準確分析出貧吸收液溫度和鍋爐給水泵能力問題，為達產達標奠定技術基礎。
今年大檢修期間，遼陽石化立足裝置原有設備，投資676萬元，通過更換兩臺鍋爐給水泵、增加一臺板式換熱器的微小改動和優(yōu)化，實現(xiàn)了環(huán)氧乙烷年增產5萬噸，年可創(chuàng)效6000萬元。同時，通過優(yōu)化改造，裝置運行成本大幅下降，多項經(jīng)濟技術指標達到歷史最好水平：裝置物耗降到710千克乙烯/噸，年增效800余萬元；綜合能耗降到256千克標油/噸，年增效1500余萬元。
