Ethylene Oxide: Tsav tsheb kev lag luam tshuaj xav tau los ntawm kev siv ntau yam
Ethylene oxide (EO), cov nplaim hluav taws kub, tsis muaj xim, nrog cov ntxhiab tsw qab me ntsis, tseem ua rau cov ntu tseem ceeb ntawm kev lag luam tshuaj lom neeg thoob ntiaj teb vim nwsKev siv ntau yam hauv paus thiab lub luag haujlwm tseem ceeb ua cov tshuaj nruab nrab. EO qhov tseem ceeb txuas mus deb tshaj li cov ntsiab lus petrochemical ib txwm muaj, ua kom muaj ntau yam ntawm cov neeg siv khoom thiab cov khoom lag luam, txhawb kev xav tau thoob ntiaj teb thoob plaws ntau qhov chaw.
Raws li cov khoom noj tseem ceeb, EO yog siv los tsim cov tshuaj tseem ceeb hauv qab xws liMonethylene glycol (MEG)thiabDiethylene glycol (DEG), uas yog qhov tseem ceeb hauv polyester fiber ntau lawm, PET resins, antifreeze formulations, detergents, plastics, adhesives, thiab lwm yam khoom siv niaj hnub. Kev siv ntau ntawm MEG hauv kev lag luam textile thiab ntim khoom thiab DEG hauv cov xim, tshuaj pleev ib ce, thiab cov ntawv siv hnyav ua rau muaj kev cuam tshuam ntev ntev -kev thov rau EO derivatives.
Dhau li ntawm cov khoom siv tshuaj, EO plays lub luag haujlwm tseem ceeb hauvkev kho mob thiab kev ua liaj ua teb. Hauv kev kho mob, nws ua haujlwm ua kom tsis muaj menyuam rau cov cua sov- cov khoom siv thiab cov khoom siv rhiab heev- raws li American Chemical Council, ntau dua50 lab cov khoom siv kho mob hauv Asmeskas ib leeg tau ua kom tsis muaj menyuam siv EO txhua hnub. EO kuj ua haujlwm ua cov tshuaj fumigant thiab sterilant rau cov khoom siv ua liaj ua teb, tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj tua kab mob fungicides, ntxiv rau nws cov ntoo khaub lig- cov haujlwm tseem ceeb.
Kev lag luam thoob ntiaj teb EO tam sim no tau txais kev txhawb nqa los ntawm kev nqis peev tseem ceeb. Industrial Info Resources qhia tiaskwv yees li US $ 6 nphom hauv peev- siv nyiaj ua haujlwmtseem tab tom hla39 nquag EO ntau lawm expansions thiab chaw tshiab, qhia tau hais tias muaj kev ntseeg siab nyob rau hauv lub compound lub sij hawm ntev - kev ua lag luam muaj peev xwm. Ib feem loj ntawm qhov kev nqis peev no yog tsom mus rau kev ntxiv peev txheej rau cov chav nyob uas twb muaj lawm es tsis yog tsim cov hauv paus hauv paus, uas qhia txog kev ua kom zoo ntawm cov khoom muaj nqis.
Asia-tshwj xeeb yog Tuam Tshoj- dominates toj roob hauv pes peev, nrog ib ncig90% ntawm kev siv nyiaj taug qabnyob hauv cheeb tsam. Tuam Tshoj qhov tseem ceeb ntawm kev nce EO tso zis yog tsav los ntawm kev xav tau hauv cheeb tsam muaj zog rau glycols, polyether superplasticizers rau kev tsim kho, khoom siv kho mob kom tsis muaj menyuam, thiab kev tsim tshuaj lom neeg ua liaj ua teb. Tuam Tshoj ib leeg tuav qhov kwv yees80% sib koom ntawm thoob ntiaj teb EO tsim muaj peev xwm, thaum lwm lub tebchaws -xws li Kaus Lim Qab Teb, Is Nrias teb, Nyiv, Brazil, Mexico, Iran, Poland, Russia, thiab Belgium- pab txhawb rau cov peev txheej ntxiv.
Major industrial players xws liSINOPEC Group, Hengli Group, thiab Tuam Tshoj National Petroleum Corporationyog cov thawj coj kev nqis peev, nrog rau kev npaj muaj peev xwm nthuav dav hauv ntau lub nroog Suav ua rau muaj txiaj ntsig zoo rau kev loj hlob ntawm cov khoom lag luam thoob ntiaj teb. Kwv yees li40% ntawm cov haujlwm no tab tom tsim kho, 35% yog nyob rau hauv kev npaj, thiab25% yog nyob rau hauv engineering theem, nrog ntau slated yuav pib ua hauj lwm ntawm2024 thiab 2029.
Txawm hais tias nws lub luag haujlwm tseem ceeb hauv kev lag luam, EO yog raug rau kev nyab xeeb thiab kev tshuaj xyuas ib puag ncig vim nwstej zaum yuav muaj kev phom sijthiab kev faib ua cov tshuaj carcinogenic hauv qee qhov kev tswj hwm. Kev lag luam uas siv EO nce ntxiv hais txog cov txheej txheem kev nyab xeeb muaj zog, kev ntsuas kev tiv thaiv qib siab, thiab kev tswj hwm kev ua raws cai los txo cov kev pheej hmoo cuam tshuam nrog kev tuav thiab emissions. Cov kev siv zog no pab ua kom EO tau txais txiaj ntsig txuas ntxiv hauv cov haujlwm xws li kev noj qab haus huv mus rau kev ua liaj ua teb thiab kev tsim tshuaj lom neeg.
Hauv cov ntsiab lus, Ethylene Oxide'sversatility raws li chemical tsev thaiv, nws lub luag haujlwm tseem ceeb hauv kev tsim cov khoom lag luam siab - kev loj hlob kawg, thiab kev nqis peev thoob ntiaj teb tsis tu ncua hauv EO muaj peev xwm ua ke txhawb nqa nws cov xwm txheej raws licore tsav tsheb ntawm kev xav tau hauv kev lag luam chemical. Txawm hais tias muaj kev nyab xeeb thiab kev tswj hwm nruj, kev lag luam tso siab rau EO daim ntawv thov dav dav qhia tias qhov kev thov yuav muaj zog nyob rau xyoo tom ntej.
