該裝置采用中國石化自主知識產(chǎn)權(quán)的雙氧水法制環(huán)氧丙烷成套技術(shù)，目前已申請發(fā)明專利31項(xiàng)，其中國外專利7項(xiàng)，取得授權(quán)5項(xiàng)，國內(nèi)專利24項(xiàng)，取得授權(quán)21項(xiàng)。裝置于2014年12月6日投料試車，當(dāng)日打通全流程，經(jīng)優(yōu)化后，產(chǎn)出聚合級環(huán)氧丙烷產(chǎn)品，實(shí)現(xiàn)“安全、環(huán)保、高效、依法”一次開車成功。
環(huán)氧丙烷是有機(jī)化工、精細(xì)化工重要的基礎(chǔ)原料，下游產(chǎn)品近百種，我國已成為全球最大的環(huán)氧丙烷產(chǎn)銷國。
