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 天津石化烯烴部眼睛向內(nèi)深度挖潛，立足優(yōu)化原料存儲(chǔ)、及時(shí)消漏以及嚴(yán)格計(jì)量原料進(jìn)出廠等細(xì)節(jié)實(shí)施從嚴(yán)管理，有效減少了乙烯生產(chǎn)中的物料損失，裝置總收率得到有效提升。前兩個(gè)月，乙烯裝置總收率累計(jì)完成99.73%，為四年來(lái)同期最好水平。
烯烴部緊盯原料源頭損失不放松。從去年5月份開始，烯烴部開始實(shí)施石腦油分儲(chǔ)分煉，有效防止了因貯存壓力不一致造成的揮發(fā)浪費(fèi)。在此基礎(chǔ)上，進(jìn)一步實(shí)施優(yōu)化，出臺(tái)了6改3集中儲(chǔ)存舉措。即：將原來(lái)儲(chǔ)存在6個(gè)儲(chǔ)罐的原料集中到3個(gè)儲(chǔ)罐內(nèi)，最大程度地減少了原料揮發(fā)損失。同時(shí)，嚴(yán)格按照操作規(guī)程進(jìn)行油品切水操作，將切水損失率牢牢控制在0.023‰以下，避免了粗放操作帶來(lái)的原料損失。烯烴部還對(duì)塔、罐及燃料氣系統(tǒng)的超壓情況進(jìn)行密切關(guān)注，及時(shí)對(duì)異常情況進(jìn)行分析、排查，避免壓力超標(biāo)、安全閥起跳造成的原料浪費(fèi)。
烯烴部將消除裝置現(xiàn)場(chǎng)跑冒滴漏現(xiàn)象作為提升裝置總收率的關(guān)鍵環(huán)節(jié)。每天組織操作人員進(jìn)行現(xiàn)場(chǎng)漏點(diǎn)排查，特別是對(duì)裝置區(qū)內(nèi)帶、卡子的體虛部位進(jìn)行測(cè)爆，對(duì)存在松動(dòng)、泄露的部位實(shí)施專業(yè)維修，將現(xiàn)場(chǎng)跑冒現(xiàn)象降至最低。據(jù)悉，僅前2個(gè)月，就消除漏點(diǎn)10余個(gè)，堵塞了真金白銀的流逝。
烯烴部充分發(fā)揮計(jì)量設(shè)施的眼睛作用，及時(shí)發(fā)現(xiàn)并消除物料損失點(diǎn)。他們每天對(duì)進(jìn)、出廠物料的計(jì)量表、結(jié)算表數(shù)量進(jìn)行對(duì)比，通過(guò)數(shù)據(jù)差異及時(shí)發(fā)現(xiàn)并消除裝臵異常點(diǎn)，保證物料顆粒歸倉(cāng)。前兩個(gè)月，及時(shí)發(fā)現(xiàn)并消除輕石腦油倒流、混合苯計(jì)量少報(bào)等數(shù)起計(jì)量異常，為科學(xué)測(cè)算乙烯裝置總收率提供了準(zhǔn)確依據(jù)。
