Ua ntej thiab tom qab lub Rooj Sib Tham Dragon, kev ua lag luam propylene oxide hauv tebchaws tau qhia txog qhov tsis ruaj khov, tom qab muaj kev nce me me hauv cov khoom lag luam ua ntej lub koob tsheej, kev ua lag luam ruaj khov, qhov kev nyuaj siab poob tom qab lub koob tsheej, tab sis nrog tus nqi poob, qee qhov txheej txheem tau mus txog kab nqi ze ntawm kev ua lag luam txhawb nqa tsim nyog, thiab tsis ntev los no tau qhia txog kev tuag tes tuag taw, tab sis kev ua lag luam ua raws li kev xav tau yuav tsum muab thiab thov, tus nqi tau ntxiv, tom qab qhov tsis sib haum xeeb, nws tseem xav tias yuav tsis muaj zog.

Ib. Sab kev muab khoom ruaj khov thiab kev ua lag luam nce ntxiv me ntsis xis nyob

Nyob rau nruab nrab Lub Rau Hli, nrog rau kev rov pib ua haujlwm ib txwm ntawm Zhenhai theem I cov khoom siv, Jiahong Cov Khoom Tshiab, Qixiang Tengda ruaj khov tsis zoo, kev muab khoom lag luam maj mam nce, mus txog qhov chaw siab tshaj plaws hauv lub xyoo, Lub Rau Hli 29 cov ntaub ntawv, cov khoom tsim tawm txhua hnub ntawm propylene oxide tuaj yeem ncav cuag 12,800 tons, kev siv peev xwm ntawm 74.67%, kev muab khoom lag luam zoo.

Nyob rau hauv lub Dragon Boat Festival, kev lag luam ua lag luam ruaj khov thiab lub teeb, sab khoom muaj qee qhov kev nyuaj siab rau lub Hoobkas tsim khoom, tus nqi tham qis, qhov kev thov qis mus rau 9200 yuan / ton (Shandong chaw pauv Hoobkas) tom qab hnub so, tag nrho cov khoom xa tuaj rov qab, txo qhov kev nyuaj siab yav dhau los ntawm kev ua lag luam kom qeeb, tab sis tsuas yog sib npaug Nissan, qee qhov kev zom zaub mov me me, tseem tsis muaj lub zog nce siab, kev ua lag luam stalemate.

Hauv kev ua raws li qhov kev txiav txim, Taixing Yida 150,000 tons / xyoo HPPO ntaus ntawv thiab Wanhua Theem 2 300,000 tons / xyoo PO / SM ntaus ntawv yuav rov pib dua thaum ntxov Lub Xya Hli, Zhejiang Petrochemical 270,000 tons / xyoo PO / SM ntaus ntawv tam sim no nyob rau hauv qhov kev ua haujlwm qis me ntsis, thiab nws yuav tsum tau muab tso rau hauv kev ua lag luam thaum pib ntawm lub hlis, nrog rau kev nce ntxiv ntawm cov txiv laum huab xeeb hauv ob sab qaum teb thiab sab qab teb. Qhov kev poob qis tsuas yog 300,000 tons / xyoo ntawm Jincheng Petrochemical kev ua raws li lossis kev tshem tawm chaw nres tsheb, tag nrho tseem yog qhov nce ntxiv, thiab sab kev muab khoom nyuaj rau kev txhawb nqa.

2. Kab rov qab them nqi ntawm cov khoom siv raw mus rau hauv kab tiv thaiv nqi

Hais txog tus nqi thiab cov txiaj ntsig, thaum lub sijhawm so Dragon Boat Festival, tus nqi ntawm cov khoom siv raw propylene thiab kua chlorine tau nce siab, tshwj xeeb tshaj yog tus nqi ntawm cov kua chlorine tau hloov pauv ntawm qhov tsis zoo mus rau qhov zoo, thiab tus nqi tau nce siab heev. Thaum lub sijhawm so Dragon Boat Festival, tus nqi ntawm hydrogen peroxide tau rov qab mus rau ntau dua 8000 yuan / ton thawj zaug. Tib lub sijhawm, los ntawm qhov kev xav ntawm HPPO txheej txheem, tus nqi ntawm hydrogen peroxide tau nce me ntsis, thiab tus nqi theoretical yog 9000-9200 yuan / ton. Kev nce ntxiv ntawm tus nqi siab ntawm HPPO cov khoom siv kuj txhawb nqa lub siab xav ua lag luam rau qee qhov, thiab qee qhov downstream saib thawj kab ntawm kev tiv thaiv ntawm CIC tus nqi, ua raws li kev yuav khoom me ntsis, thiab lub khw muag khoom raug kaw ib ntus ntawm 9200 yuan / ton tus nqi tom qab lub koob tsheej.

Hauv kev ua raws li qhov no, tus nqi ntawm propylene yuav muaj qhov poob qis me ntsis, thiab tus nqi ntawm cov kua chlorine thiab hydrogen peroxide feem ntau yog sib sau ua ke, txawm hais tias tus nqi tuaj yeem siv ua kab tiv thaiv los ua lub luag haujlwm txhawb nqa hauv tus nqi, tab sis qhov cuam tshuam ntawm kev muab khoom thiab kev thov tseem ceeb dua.

3. Kev yuav khoom hauv qab dej tawg khiav ceev faj tos

Los ntawm qhov kev xav ntawm sab kev thov khoom, kev yuav khoom yog qhov sib txawv thoob plaws lub hlis, thiab qhov kev xav tsis zoo thawj zaug tseem yog qhov xav tau ua raws li, thiab cov chaw nres nkoj tsis muaj lub siab xav khaws cia. Qee zaum, kev saib xyuas cov khoom siv tsis raug cai hauv lub hlis ua rau qhov chaw nruj me ntsis, thiab kev yuav khoom hauv qab yog me me, tab sis kev ruaj khov tsis txaus. Qhov txiaj ntsig ntawm kev lag luam propylene glycol thiab cawv ether thib ob yog qis, thiab kev siv peev xwm ntawm kev lag luam yog qis, uas muaj kev txhawb nqa tsawg rau kev lag luam cyclopropylene.

Lub Xya Hli tom ntej no tseem yog lub caij tsis yog lub caij muag khoom, ua ke nrog kev tos thiab saib cov khoom siv ntxiv, kev xav ntawm cov khoom muag tsis zoo thiab txuas ntxiv mus yuav khoom ceev faj, uas xav tias yuav muaj kev txhawb nqa tsawg rau kev ua lag luam.

四. Nws yuav tsum tsis muaj zog tom qab qhov kev tsis sib haum xeeb

Xaus Lus (lub sijhawm luv luv):Kev muab khoom thiab kev thov ntawm kev ua lag luam cyclic yog nyob rau hauv qhov sib npaug zoo, thiab nws nyob rau hauv qhov teeb meem rau lub sijhawm tam sim no, tab sis lub lim tiam tom ntej, nrog rau kev nce ntawm qee cov khoom siv thaum pib ntawm lub hlis, tej zaum yuav muaj kev poob qis me ntsis.

Xaus lus (nruab nrab thiab ntev):Thaum Lub Xya Hli, qhov kev nce ntxiv ntawm sab kev muab khoom yog qhov pom tseeb, kev txhawb nqa sab nraud ntawm lub caij tsis yog qhov txwv, nrog rau kev muab khoom thiab kev thov ntau dua thiab ntau dua, thawj kab nqi lossis kev cuam tshuam yog txwv, tus nqi lag luam tseem xav tias yuav poob qis feem ntau hauv qhov ntau thiab tsawg, qhov sib txawv yog qis dua, tab sis tus nqi ntawm chlorol txoj kev ua kab thib ob ntawm kev tiv thaiv yuav muaj qee qhov kev txhawb nqa rau kev ua lag luam, thiab qhov tsis zoo yog txwv ntau dua. Nws xav tias tus nqi ntawm cyclopropyl yuav hloov pauv hauv qhov ntau ntawm HPPO tus nqi thiab chlorol tus nqi, tab sis nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov kev hloov pauv tsis tau xav txog ntawm qhov chaw ntawm lub cuab yeej thiab qhov cuam tshuam ntawm lub zog kub siab txwv hauv lub caij ntuj sov. Lub logic ua haujlwm ntawm tus nqi ntawm cyC tseem yog raws li kev muab khoom thiab kev thov, ntxiv los ntawm tus nqi.

Kev ceeb toom txog kev pheej hmoo: kev tsis paub meej ntawm lub sijhawm nce ntxiv ntawm qhov chaw ntawm lub cuab yeej; Yog tias tus nqi siab tom qab lub tuam txhab pib ua haujlwm; Sab kev thov kev siv tiag tiag tsaws.
