Ma inline density mita amafunikira kuti pakhale kuwunika kwa mankhwala nthawi yeniyeni mu kapangidwe ka linalyl acetate. Kuwerengera kolondola kwa density (cholinga: 0.890–0.894 g/cm³) kumathandizira kuwongolera kwa esterification reaction pogwiritsa ntchito ma density mita. Deta yopitilira imatsimikizira kuwunika kwa acetyl chloride feed rate, kupewa kuchuluka kwa mankhwala ochulukirapo, zomwe zimapangitsa kuti hydrogen chloride ikhale yambiri komanso kuti mafuta onunkhira asanunkhike.
Kuyeza mwachindunji mkati mwa mzere kumachotsa kuchedwa pakati pa kupanga ndi kusanthula kwa labotale, kuthandizira kukonza njira mwachangu komanso kuzindikira zolakwika. Kuphatikiza chizindikiro cha 4-20mA ndi kulumikizana kwa RS485 kumalola kutumiza deta nthawi yeniyeni mokhazikika komanso mosasokoneza ngakhale m'malo osungunuka achilengedwe komanso opanda madzi. Kuwongolera mkati mwa mzere kumawonjezera kusintha kwa zinthu zopangira ndi 30%, kuchepetsa zinyalala za acetyl chloride ndi linalool.
Kuwunika kodalirika kwa kuchuluka kwa zinthu kumakulitsa kutsata miyezo ya kuyera ya GB 29985-2013.Miyezo yolimbana ndi dzimbiriPogwiritsa ntchito matupi a Hastelloy ndi PTFE, zinthuzi zimasunga kulondola pamene acetyl chloride ikuwonekera, kuonetsetsa kuti zipangizozo ndi zolondola.

Kuyeza kuchuluka kwa mankhwala m'thupi ndikofunikira kwambiri pakuwunika momwe mankhwala amagwirira ntchito popanga linalyl acetate, komwe kusinthasintha kwa kuchuluka kwa mankhwala kumakhudza mwachindunji kuwongolera momwe mankhwala amagwirira ntchito. Kuwunika nthawi zonse nthawi yeniyeni kumakhazikitsa kuchuluka kwa chakudya cha linalool ndi acetyl chloride, kukonza kusintha kwa zinthu zopangira ndikuchepetsa zinyalala zosungunulira. Kupewa kokha kuchuluka kwa acetyl chloride pogwiritsa ntchito inline density mita kumachepetsa kupanga kwa HCl yochulukirapo, kuonetsetsa kuti chloride yokhazikika imalamulira fungo la hydrogen m'mafuta onunkhira.
Kukonza ma foroko ochulukirachulukiraNdi matupi a Hastelloy ndi PTFE lining zimapirira zosungunulira zachilengedwe zosasungunuka ndipo zimalimbana ndi dzimbiri la acetyl chloride, kusunga kudalirika kwa chizindikiro kuti chiwongolere njira. Kulumikizana kwa RS485 kophatikizidwa ndi kutulutsa kwa chizindikiro cha 4-20mA kumathandizira kusamutsa deta mosasunthika ku ma PLC opanga, zomwe zimathandiza kuzindikira zolakwika nthawi yomweyo komanso kudzipangira zokha. Kulondola kumeneku pakulamulira njira kumatsimikizira kutsatira miyezo yapamwamba ya linalyl acetate (GB 29985-2013) ndikuwonjezera magwiridwe antchito opanga mpaka 30%.
Chidule chaEkuyeretsa kwaLinalool
Kupitirizabe kuyeretsa kwa linalool ndi acetyl chloride mu zosungunulira zachilengedwe zopanda madzi kumapanga linalyl acetate, gawo lofunika kwambiri la mafuta onunkhira. Njirayi imafuna kuyang'anira molondola kuchuluka kwa chakudya cha acetyl chloride kuti ilamulire stoichiometry ya reactant ndikuchepetsa fungo la hydrogen la chloride mu mafuta onunkhira. Mita ya inline density—yokonzedwa kuti ikhale 0.890–0.894 g/cm³ kumapeto kwa distillation—imapereka kuyang'anira momwe mankhwala amachitira nthawi yeniyeni, kuthandizira kuwongolera njira zodziyimira pawokha komanso miyezo yabwino ya linalyl acetate (GB 29985-2013).
Chogulitsa chochokera mu reactor chimalowa mu gawo la distillation, komwe Lonnmeter yolimbana ndi dzimbiri yokhala ndi Hastelloy ndi PTFE lining imawonetsetsa kuti muyeso ndi wolondola mumlengalenga wa acetyl chloride. Pamene kuchuluka kwa linalyl acetate, makina odziyimira pawokha amatsogolera kutulutsa kwa zinthu, kuzilekanitsa ndi zosakaniza zosagwiritsidwa ntchito mozama kwambiri. Zosakaniza izi zimabwezeretsedwanso zokha kudzera mu valavu kuti ziwongolere kusintha kwa zinthu zopangira ndikuchepetsa zinyalala, zomwe zimapangitsa kuti ntchito yopanga ikhale yogwira mtima ndi 30%.
Kulumikizana kwa RS485 kophatikizidwa ndi zotuluka za chizindikiro cha 4-20mA zimapereka kuyang'anira kosalekeza kwa njira ndi kuzindikira zolakwika, kuthandizira kukonza mwachangu ndikuchepetsa kusinthasintha kwa mtundu wa chinthu. Kuphatikiza kosasunthika kwa mita ya inline density mita kumathandizira kugwiritsa ntchito zosungunulira ndikusunga zinthu zopanda madzi zomwe ndizofunikira pakuwongolera momwe zinthu zilili.

Mavuto mu Kuyeza Kuchulukana kwa Inline
Kuthamanga kwa density kumavutitsa esterification ya multiphase, zomwe zimapangitsa kuti chiyero cha linalyl acetate chitsike pansi pa muyezo wa GB 29985-2013. Kusakaniza komwe kulipo, kusintha kwa kutentha, ndi kusinthasintha kwa chakudya cha reagent kumasokoneza kuwerenga kwa density, zomwe zimafooketsa kuwongolera kwa esterification reaction pogwiritsa ntchito ma density meters. Acetyl chloride imaukira mwachangu malo onyowa ndi sensor, makamaka chitsulo chosapanga dzimbiri, zomwe zimapangitsa kuti isagwire ntchito msanga. Ma Hastelloy bodies okha omwe ali ndi PTFE lining ndi omwe amaonetsetsa kuti ma density meters osagonjetsedwa ndi dzimbiri kuti agwiritsidwe ntchito ndi mankhwala pansi pa acetyl chloride nthawi zonse.
Kusankha zinthu mwachizolowezi sikungapereke kuwunika momwe mankhwala amagwirira ntchito nthawi yeniyeni popanga linalyl acetate. Kuzindikira mochedwa zolakwika kumabweretsa kuchuluka kwa acetyl chloride komanso kuchuluka kwa hydrogen chloride, zomwe zimayambitsa kusintha kwa fungo. Kusakwanira kwa magawo pakusungunuka kwa madzi kumapangitsa kuti chakudya chosagwiritsidwa ntchito chidetsedwe, zomwe zimalepheretsa kuwunika kuchuluka kwa chakudya cha acetyl chloride komanso kuchepetsa kusintha kwa zinthu zopangira.
Machitidwe amphamvu osungunula zinthu amasokoneza kulumikizana kwa RS485 m'mamita ochulukirachulukira a mafakitale ndipo amasokoneza kuphatikizana kwa chizindikiro cha 4-20mA chokhazikika kuti chiwongolere njira. Kusakhazikika kwa chizindikiro kosalekeza kumalepheretsa kuyang'anira njira mosalekeza komanso kuzindikira zolakwika, kuchepetsa phindu la kupanga ndikulepheretsa kutsatira miyezo ya khalidwe la linalyl acetate.
Ubwino Wophatikiza Ma Inline Density Meters
Kulamulira kwa density nthawi yeniyeni kumayendetsa mphamvu ya valve pa magawo olekanitsa, kukweza phindu la linalyl acetate ndi zoposa 30% poyerekeza ndi njira zozikidwa pa batch. Inline mita nthawi yomweyo imasonyeza kuchuluka kwa acetyl chloride, kuletsa kupangika kwa HCl mopitirira muyeso ndikusunga kuwongolera kolondola kwa fungo la chloride hydrogen muzinthu zonunkhiritsa. Cylindrical density mita yokhala ndi matupi a Hastelloy ndi PTFE lining imalimbana ndi kutupira kwa acetyl chloride, kuthandizira kuyang'anira kwa nthawi yayitali kwa mankhwala mu kapangidwe ka linalyl acetate. Zizindikiro zophatikizika za RS485 ndi 4-20mA zimapereka deta yokhazikika komanso yolondola ku machitidwe apakati a PLC kapena DCS pansi pa mikhalidwe yamankhwala amphamvu. Kuyankha kosalekeza kwa inline kumakulitsa kusinthika kwa feed linalool ndi acetyl chloride, kuchepetsa zinyalala za zinthu zopangira ester ndikuwonjezera kuyera kwa zotuluka kuposa 95%. Kuwunika kokhazikika komwe kumatsata kokha kumathandizira kutsatira miyezo ya GB 29985-2013 ya linalyl acetate, ngakhale munjira zomwe zimagwiritsidwa ntchito ndi anhydrous organic solvents.
Pemphani mtengo wa Lonnmeter inline density meter kuti muthane ndi esterification reaction control pogwiritsa ntchito density meters mu linalyl acetate synthesis. Onetsetsani kuti acetyl chloride feed rate ikuyang'aniridwa kuti mupewe kuchuluka kwa acetyl chloride komanso fungo losafunikira la chloride hydrogen mu mafuta onunkhira.
