為增大環(huán)氧乙烷產(chǎn)量，茂名石化化工分部乙二醇車間以催化劑優(yōu)化為核心，運(yùn)用多種技術(shù)手段，突出抓好收率提升工作；通過與催化劑專利商、同行業(yè)專家溝通探討，結(jié)合歷史數(shù)據(jù)，明確調(diào)整控制范圍，并對(duì)反應(yīng)系統(tǒng)抑制劑的加入量進(jìn)行以克為單位的微調(diào)整，提高其選擇性能。通過優(yōu)化新裝置C402塔頂氣、串聯(lián)運(yùn)行乙二醇裝置環(huán)氧乙烷精制塔C302/C302N做大環(huán)氧乙烷采出量。同時(shí)深入質(zhì)量管理，完善質(zhì)量管理規(guī)定，明確要求班組加強(qiáng)產(chǎn)品餾出口、產(chǎn)品中間罐質(zhì)量指標(biāo)、原料及生產(chǎn)重要采樣點(diǎn)的分析數(shù)據(jù)跟蹤，發(fā)現(xiàn)異常及時(shí)做好生產(chǎn)調(diào)整，實(shí)現(xiàn)質(zhì)量監(jiān)控常態(tài)化。
同時(shí)，他們需減產(chǎn)效益靠后的乙二醇產(chǎn)品，茂名石化化工分部成立乙二醇車間減產(chǎn)乙二醇產(chǎn)品攻關(guān)小組，制定6大點(diǎn)優(yōu)化生產(chǎn)和管理措施，于4月10日達(dá)到減產(chǎn)乙二醇產(chǎn)品至120t/天的目標(biāo)。減產(chǎn)之前乙二醇產(chǎn)量約168噸/天，減產(chǎn)項(xiàng)目完成及降本增效情況措施實(shí)施后，乙二醇產(chǎn)量約115噸/天，每日減產(chǎn)53噸，每日可減少效益損失超3萬元。(蕭明麗虞清）
