3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 中韓石化環(huán)氧芳烴部做足產(chǎn)品結(jié)構(gòu)優(yōu)化和節(jié)能降耗文章，持續(xù)攻關(guān)創(chuàng)效傳佳音。
當前，環(huán)氧乙烷是中韓石化化工板塊效益最好的產(chǎn)品。環(huán)氧芳烴部EO/EG裝置持續(xù)優(yōu)化產(chǎn)品結(jié)構(gòu)，盡可能多產(chǎn)環(huán)氧乙烷。8月高溫季節(jié)，環(huán)氧乙烷產(chǎn)品塔塔頂冷凝器冷卻效果降低，引起塔壓波動。裝置及時優(yōu)化操作，微升塔操作壓力，提高冷卻效果。環(huán)氧乙烷產(chǎn)品塔塔頂脫甲醛線在高溫下易聚合堵塞，裝置人員增加排放量，確保甲醛排放順暢，保證了產(chǎn)品質(zhì)量合格、塔壓穩(wěn)定。夏季環(huán)氧乙烷裝車安全風險高，裝置與承運商不斷優(yōu)化裝車、運輸?shù)拳h(huán)節(jié)，保證車輛當天配送。8月份，EO/EG裝置生產(chǎn)環(huán)氧乙烷2.09萬噸，同比增長65.4%，創(chuàng)歷史新高，創(chuàng)效顯著。
該部EO/EG裝置重點從技術(shù)攻關(guān)和管理入手狠抓節(jié)能降耗。他們根據(jù)銀催化劑運行條件，逐步降低空速，降低高壓蒸汽用量1噸/時，能耗降低2.34千克標油/噸。根據(jù)氣溫變化，及時優(yōu)化循環(huán)冷卻水用量，8月循環(huán)冷卻水用量較上月減少1466噸/時，環(huán)比下降7.13%。積極調(diào)整EO吸收水量，氣溫低時EO吸收水量降至1150噸/時，節(jié)約電耗80千瓦/時。該部碳四芳烴聯(lián)合裝置通過對揚程富余的5臺離心泵進行葉輪切削，每年可節(jié)約電費10萬元。
