去年，烯烴分部致力優(yōu)化生產(chǎn)，在原料和中間罐區(qū)新增乙烯裝車(chē)設(shè)施，全年裝車(chē)4萬(wàn)噸，去年4月份單月裝車(chē)9400噸，創(chuàng)歷史新高，全年創(chuàng)效3000萬(wàn)元。通過(guò)更改流程，使丙烯裝車(chē)設(shè)施返回的氣相直接返回裂解氣壓縮機(jī)回?zé)?，避免了氣相余料排放火炬造成浪費(fèi)，同時(shí)減少了環(huán)境污染，全年創(chuàng)效74.8萬(wàn)元。
在調(diào)整結(jié)構(gòu)方面，原料和中間罐區(qū)石腦油由武漢石化管輸至乙烯石腦油罐區(qū)，經(jīng)調(diào)整結(jié)構(gòu)、資源優(yōu)化后，增加了石腦油原料總量，一年創(chuàng)效3億元。去年3月份，新增碳五拔頭油罐組T-901順利投用，改善了裂解原料質(zhì)量，避免了乙烯裝置輕烴爐生產(chǎn)波動(dòng)和結(jié)焦堵塞，年創(chuàng)效約2.2億元。
該部組織專(zhuān)項(xiàng)攻關(guān)小組優(yōu)化全廠乙烯外送系統(tǒng)流程，實(shí)施了提高乙烯裝置乙烯外送流程穩(wěn)定性的改造方案，在乙烯球罐乙烯泵出口增加一臺(tái)汽化器、增加調(diào)節(jié)閥，確保氣化系統(tǒng)穩(wěn)定運(yùn)行。該項(xiàng)目于去年11月中旬投用后，停運(yùn)了低溫罐區(qū)乙烯輸送泵及相關(guān)壓縮機(jī)，節(jié)電1300千瓦/時(shí)，節(jié)支633.2萬(wàn)元。
