Pa nthawi ya njira zofunika kwambiri zoyeretsera mafuta oyera—kuphatikizapo hydroisomerization dewaxing ndi njira yochotsera zodetsa—kuchulukana kuyenera kulamulidwa bwino kuti kukwaniritse zofunikira. Mwachitsanzo, ngati kupotoka kwa kuchulukana kwapezeka panthawi yochotsa hydrocarbon dewaxing, ogwiritsa ntchito amatha kusintha kutentha kapena kuchuluka kwa catalyst nthawi yomweyo, zomwe zimathandiza kupewa kukhuthala kwapadera kapena kapangidwe kake kosafunikira. Izi zimathandiza kutsimikizika kwachangu kwa zinthu, kuchepetsa chiopsezo chobwezedwa, ndikufulumizitsa kutumiza popereka umboni weniweni kuti gawo lililonse likugwirizana ndi miyezo yomwe imayikidwa panthawi yopanga mafuta oyenerera.
Kuyeza kuchuluka kosalekeza kumathandizanso kuwongolera kukhuthala kwa mafuta mu zida zapamwamba zowunikira njira zoyeretsera mafuta. Chifukwa kukhuthala ndi kuchuluka kwa mafuta zimagwirizanitsidwa kwambiri—makamaka pambuyo pa njira zazikulu monga kuyeretsa mafuta kapena kuchotsa gumming—kuyang'anira kosalekeza kumalola kukonza bwino njira. Kuyeza nthawi yeniyeni kumachepetsa kupanga zinthu zosafunikira, kuchepetsa kutayika kwa zokolola chifukwa chosakaniza kapena kubwezeretsanso, komanso kumathandizira kutsatira malamulo okhwima komanso ogwiritsira ntchito poletsa mafuta ndi mafuta oyera.
Ogwira ntchito amagwiritsa ntchito deta yeniyeni kuchokera ku mita yolowera mkati panthawi yotumiza zinthu ndi kusakaniza kuti atsimikizire kuti zinthu zomwe zatumizidwa kapena zotumizidwa zikugwirizana ndi zofunikira pamsika za kuchuluka kwa viscosity index, mtundu, ndi kuyera. M'malo modalira kusanthula kwa labotale nthawi ndi nthawi, kuyeza kosalekeza pogwiritsa ntchito zida za Lonnmeter kumapereka mayankho mwachangu. Mwachitsanzo, pamene kuchuluka kwa mafuta opaka mafuta kumakwera kunja kwa zenera loyembekezeredwa la njira yogwirira ntchito—mwina chifukwa cha kusalinganika kwa ma catalyst ochotsa madzi kapena kusintha kosayembekezereka kwa chakudya—njira zowongolera mkati mwa njira zimakhala zotheka, kuonetsetsa kuti chinthu chomaliza chimakhala chokonzeka pamsika nthawi zonse.
M'malo oyeretsera okha komanso amakono, kuphatikiza kuyang'anira kuchulukana ndi kukhuthala mu closed-loop control kumathandiza oyeretsera kusintha zinthu mwachangu ndikusunga mtundu wogwirizana wa zotulutsa. Njira zotere sizimangowonjezera kutsimikizika kwa khalidwe, komanso zimathandizira kuyendetsa bwino ntchito yoyeretsera, zimachepetsa njira zogwirira ntchito pamanja, ndikufulumizitsa kutulutsa mafuta omalizidwa pamsika, zomwe zimathandiza kukwaniritsa zosowa za makasitomala ndi malamulo zomwe zimasinthasintha mwachangu kuti zikhale zoyera komanso zogwira ntchito.
Kusintha kwa njira yoyezera mosalekeza komanso molunjika ndikofunikira kwambiri pakupititsa patsogolo kukonza njira, kuchepetsa kupanga zinthu zomwe sizili zodziwika bwino, kuthandizira kuchotsa zinyalala pakuyeretsa mafuta, komanso kupereka kusinthasintha kwa zinthu mumafuta opaka mafuta ndi mafuta oyera omwe amafunidwa ndi mankhwala, zodzoladzola, ndi mafakitale.
Mafunso Ofunsidwa Kawirikawiri
Kodi hydroisomerization dewaxing ndi chiyani ndipo n'chifukwa chiyani ndikofunikira kwambiri popanga mafuta odzola?
Kuchotsa mafuta m'thupi pogwiritsa ntchito hydroisomerization ndi njira yomwe imasintha ma paraffin aatali, owongoka (abwinobwino) omwe amapezeka m'magawo amafuta a sera. Kudzera mu kusintha kwa catalytic, ma paraffin awa amasinthidwa kukhala ma isoparaffin okhala ndi nthambi. Izi zimachepetsa kwambiri ma pour ndi cloud points a mafuta oyambira, motero zimawonjezera kuyenerera kwawo kupanga mafuta odzola—makamaka pazinthu zomwe ziyenera kugwira ntchito bwino kutentha kochepa. Kuchotsa mafuta m'thupi ndikofunikira chifukwa kumathandiza kupanga mafuta odzola omwe amakana kuuma m'malo ozizira, kuthandizira magwiridwe antchito apamwamba komanso kukhazikika pamene akukulitsa zokolola ndikusunga zofunikira za mankhwala.
Kodi kuyeza kosalekeza kwa kuchuluka kwa mafuta kumathandiza bwanji kuti mafuta oyera azigwiritsidwa ntchito bwino?
Ukadaulo woyezera kuchuluka kwa madzi nthawi zonse umayang'anira nthawi yeniyeni kuchuluka kwa madzi mkati mwa mizere ya ntchito. Mwa kupereka mayankho nthawi yomweyo, ogwira ntchito amatha kusintha momwe zinthu zikuyendera mwachangu kuti azilamulira bwino njira. Izi zimapangitsa kuti zinthu zigwirizane bwino, kugwiritsa ntchito bwino zinthu, komanso kuyankha mwachangu pakabuka kusintha kwa zinthu—monga kusintha kapangidwe ka chakudya kapena kuipitsidwa mwangozi. Kuchotsa zitsanzo zamanja kumawonjezera kuchuluka kwa mafuta omwe amatuluka m'thupi ndipo kumachepetsa nthawi yogwira ntchito, zomwe zimapangitsa kuti mafuta oyera azigwiritsidwa ntchito bwino. Makina okhala ndi mita yoyezera kuchuluka kwa madzi, monga omwe amapangidwa ndi Lonnmeter, amachita gawo lofunikira pakukwaniritsa izi poonetsetsa kuti ma profiles olondola komanso odziyimira pawokha nthawi yonse yoyeretsera. Kutsata kuchuluka kwa madzi nthawi yeniyeni kumathandiza pakusakaniza, kulekanitsa, ndi kusamutsa zinthu, kuchepetsa zochitika zomwe sizikudziwika bwino komanso kukonza kukhazikika kwa zokolola.
N’chifukwa chiyani kulamulira kukhuthala kwa mafuta n’kofunika kwambiri popanga mafuta abwino kwambiri opaka mafuta?
Kukhuthala kumatanthauza momwe mafuta opaka mafuta amayendera komanso mphamvu yoteteza filimu ya mafuta opaka mafuta. Kusunga kukhuthala kolondola komanso kolunjika kumaonetsetsa kuti mafutawa apereka mafuta ofunikira kutentha kosiyanasiyana komanso kupsinjika kwa makina. Ngati kukhuthala kutsika, mafuta amatha kulephera, zomwe zimapangitsa kuti zida ziwonongeke; ngati akwera kwambiri, mphamvu zimatayika ndipo kuyenda kwake sikugwira ntchito bwino. Kuyang'anira kukhuthala kosalekeza kumathandiza kukonza njira mwachangu, kuthandiza opanga kutsatira miyezo yokhwima ndikupereka mafuta opaka mafuta okhazikika komanso ogwira ntchito bwino. Mita ya kukhuthala yoperekedwa ndi Lonnmeter imalola kutsata ndi kusintha nthawi yeniyeni, kuthandizira kuwongolera khalidwe komanso kutsatira magiredi ogwira ntchito m'makampani.
Kodi kuchotsa gumming kumagwira ntchito yotani pa ubwino wonse wa mafuta oyera oyeretsedwa?
Kuchotsa gumming ndi sitepe yoyambira yoyeretsa mafuta oyera, yolunjika ku ma phospholipid ndi ma ayoni achitsulo omwe angasokoneze kuyera kwa mafuta, kukhazikika, komanso moyo wautali. Ngati sakuthandizidwa, zonyansazi zimayambitsa kuwonongeka ndikusokoneza mafuta, zomwe zimafooketsa kukonza kwapansi ndi magwiridwe antchito otsiriza. Njira monga madzi, asidi, kapena kuchotsa gumming pogwiritsa ntchito enzymatic zimachotsa zonyansazi, zomwe zimapangitsa kuti zinthu zopanda utoto komanso zokhazikika zipezeke. Kusanthula kolondola komanso kwanthawi yeniyeni—komwe kumachitika pogwiritsa ntchito zida zamakono zowunikira njira—kumatsimikizira kugwira ntchito kwa kuchotsa gumming ndikuwonetsetsa kuti zonyansa sizipitirirabe mpaka magawo oyeretsera pambuyo pake.
Kodi zida zowunikira momwe zinthu zilili zimathandiza bwanji kuchotsa zinthu zodetsedwa mu mafuta oyenga?
Zipangizo zamakono zowunikira njira—kuphatikizapo zoyezera kuchuluka kwa zinthu zomwe zili mkati mwa mzere ndi zoyezera kuchuluka kwa zinthu zomwe zili mkati mwa mzere—zimathandiza kuyeza msanga, mosasokoneza zinthu monga sera ndi chingamu pamene zikusintha panthawi yonse yoyeretsera mafuta. Zipangizozi zimapereka mayankho ofunikira nthawi yomweyo kuti zinthu ziyende bwino komanso kuti zichotse zinthu zomwe zili mkati mwa mzere zisanakhudze mtundu wa chinthucho. Mwa kuphatikiza zida zotere, oyeretsera amatha kuchotsa zinthu zomwe zili mkati mwa mzere popanda kusokoneza kupanga, zomwe zimapangitsa kuti pakhale miyezo yapamwamba komanso kutulutsa zinthu kokhazikika. Mayankho a Lonnmeter oyezera mkati mwa mzere ndi ofunikira pakutsata zinthu zomwe zili mkati mwa mzere ndipo amawonjezera phindu lalikulu pakukonza bwino zinthu komanso kutsimikizira kuti zinthuzo zili bwino.
