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 近日，廣州石化1號(hào)聚丙烯裝置利用氫調(diào)法生產(chǎn)“三高”(高熔指、高剛性、高沖擊)產(chǎn)品490多噸，通過(guò)精細(xì)管理、優(yōu)化操作，過(guò)渡料較上一周期下降了23.76%。
本次生產(chǎn)的產(chǎn)品J890、J860具有高熔指、高剛性、高沖擊的特點(diǎn)，反應(yīng)釜粉料熔指從?？氐?0g/10min提高到100-150g/10min，對(duì)液相本體聚合的裝置來(lái)說(shuō)，反應(yīng)器的壓力控制非常困難。
生產(chǎn)前，裝置技術(shù)人員分析總結(jié)之前的生產(chǎn)經(jīng)驗(yàn)，多舉措確保安全平穩(wěn)生產(chǎn)。轉(zhuǎn)產(chǎn)前一天進(jìn)行高氫調(diào)敏感性的專用改性劑試生產(chǎn)，把握反應(yīng)規(guī)律；精準(zhǔn)測(cè)定氫氣加入時(shí)間和體積，最大限度縮短熔指調(diào)整時(shí)間；恢復(fù)投用色譜伴熱，確保氫濃度和乙烯濃度的測(cè)量準(zhǔn)確；優(yōu)化造粒單元生產(chǎn)參數(shù)，確保造粒擠壓機(jī)穩(wěn)定運(yùn)行等。
生產(chǎn)期間，漿液線調(diào)節(jié)閥突然關(guān)閉，班組操作人員第一時(shí)間啟動(dòng)應(yīng)急預(yù)案，立即切換漿液線；儀表人員迅速趕到現(xiàn)場(chǎng)解決調(diào)節(jié)閥問(wèn)題；分析人員做好兩小時(shí)一次的樣品數(shù)據(jù)分析，為工藝人員及時(shí)調(diào)整乙烯和氫氣的加入量提供數(shù)據(jù)支持。裝置主管和技術(shù)管理人員全時(shí)程監(jiān)控，與各相關(guān)單位人員密切配合，不僅確保了產(chǎn)品的生產(chǎn)任務(wù)，而且過(guò)渡料大幅較少。
