Mita dze inline density dzinodiwa kuti pave nekutarisa reaction yemakemikari panguva chaiyo mukugadzirwa kwelinalyl acetate. Kuverengwa kwe density chaiyo (chinangwa: 0.890–0.894 g/cm³) kunogonesa automated esterification reaction control ne density metres. Data rinoenderera mberi rinovimbisa kuti acetyl chloride feed rate monitoring, kudzivirira overdose, izvo zvinotungamira kuhydrogen chloride yakawandisa uye kusanhuwa muzvigadzirwa zveperfume.
Kuyera zvakananga mukati mechinhu kunobvisa kunonoka pakati pekugadzirwa uye kuongororwa kwerabhoritari, zvichitsigira kugadziriswa kwemaitiro nekukasika uye kuonekwa kwezvisina kujairika. Kubatanidzwa kwechiratidzo che4-20mA nekutaurirana kweRS485 kunobvumira kutapurirana kwedata panguva chaiyo, kusingapindiki, kunyangwe munzvimbo dzine hukasha, dzisina mvura. Kudzora mukati mechinhu kunowedzera kushandurwa kwezvinhu zvisina kugadzirwa neanopfuura 30%, zvichideredza marara eacetyl chloride nelinalool.
Kutarisa huwandu hwezvigadzirwa nenzira yakavimbika kunovandudza kutevedzera mitemo yekuchena kwezvigadzirwa zveGB 29985-2013.Mamita ekudzivirira ngura anodzivirira nguraNeHastelloy bodies uye PTFE lining, zvinochengetedza kururama kana zvasangana neacetyl chloride, zvichivimbisa kuti michina yacho yakanyatsogadzirwa. Zvishandiso izvi zvakakosha kuti pave nekutarisa nguva dzose maitiro, kudzivirira kusiyana kwehuwandu, uye kuchengetedza mhando yezvinonhuwira pahukuru.

Kuyerwa kweInline Density mu LinalylAsetateSkugadzira
Kuyerwa kwehuwandu hwemukati kwakakosha pakutarisa mashandiro emakemikari mukugadzirwa kwelinalyl acetate, uko kusiyana kwehuwandu kunokanganisa zvakananga kudzora mashandiro e esterification. Kutarisa nguva dzose panguva chaiyo kunodzikamisa huwandu hwekudya hwelinalool ne acetyl chloride, zvichiita kuti shanduko yezvinhu zvakasvibiswa ibudirire uye kuderedza marara e solvent. Kudzivirira otomatiki huwandu hwe acetyl chloride overdose uchishandisa inline density metres kunoderedza kuumbwa kweHCl yakawandisa, zvichiita kuti chloride hydrogen error control igare yakasimba muzvigadzirwa zve perfume.
Kugadzirisa huwandu hweforogoine Hastelloy bodies uye PTFE lining inodzivirira anhydrous organic solvents uye inodzivirira acetyl chloride corrosion, ichichengetedza kuvimbika kwesignal yekudzora maitiro. Kutaurirana kwakabatana kweRS485 uye kubuda kwesignal ye4-20mA kunotsigira kutamiswa kwedata mushe kune maPLC ekugadzira, zvichiita kuti kuonekwa kweanomaly nekukurumidza uye otomatiki yekuita. Kururama uku mukudzora maitiro kunovimbisa kutevedzera mwero wemhando yelinalyl acetate (GB 29985-2013) uye kunowedzera kushanda zvakanaka kwekugadzira kusvika ku30%.
Pfupiso yeEkucheneswa kweLinalool
Kuramba uchiisa linalool mu acetyl chloride mu anhydrous organic solvents kunoburitsa linalyl acetate, chikamu chikuru cheperfume. Maitiro aya anoda kunyatsoongorora acetyl chloride feed rate kudzora reactant stoichiometry uye kuderedza kunhuhwirira kwe chloride hydrogen muzvigadzirwa zveperfume. Inline density metres—yakagadzirirwa 0.890–0.894 g/cm³ pakupera kwe distillation—inopa kutarisa kwemakemikari panguva chaiyo, ichitsigira automated process control uye mwero wemhando ye linalyl acetate (GB 29985-2013).
Chigadzirwa chinobva mureactor chinopinda muchikamu chekunyungudutsa, uko mamita eLonnmeter anodzivirira ngura ane Hastelloy nePTFE lining anovimbisa kusimba kwekuyera munzvimbo dzine aggressive acetyl chloride atmospheres. Kana density ichiratidza pure linalyl acetate, automated valve systems inotungamira kubuda kwayo kuunganidzwa, ichiiparadzanisa kubva kune misanganiswa isina kugadziriswa yakawanda. Misanganiswa iyi inodzokororwa otomatiki kuburikidza nevharuvhu kudzora kuvandudza shanduko yezvinhu zvakabikwa uye kuderedza marara, zvichiwedzera kushanda zvakanaka kwekugadzira neanopfuura 30%.
Kutaurirana kwakabatana kweRS485 uye kubuda kwechiratidzo che4-20mA zvinopa kutarisa kwemaitiro nguva dzose uye kuona zvisina kunaka, zvichitsigira zviito zvekugadzirisa nekukurumidza uye kuderedza kutsauka mumhando yechigadzirwa. Kubatanidzwa kwakanyatsonaka kwemamita ehuwandu hwezvinhu mukati kunogadzirisa kushandiswa kwe solvent uye kunochengetedza mamiriro emvura akakosha pakudzora reaction ye esterification.
Kugadzirwa kweLinalool neLinalyl acetate

Matambudziko muInline Density Measurement
Kuyerera kwehuwandu hwezvinhu kunokanganisa kuumbwa kwe esterification yezvikamu zvakawanda, zvichiita kuti linalyl acetate purity idzike pasi peGB 29985-2013 standard. Kusanganiswa kwenzvimbo, kuchinja kwetembiricha, uye kushanduka kwe reagent feed zvinokanganisa kuverenga kwe density, zvichikanganisa esterification reaction control ne density metres. Acetyl chloride inokurumidza kurwisa nzvimbo dzakanyorova dze sensor, kunyanya simbi isina ngura, zvichikonzera kutadza kushanda zvakanaka. Hastelloy bodies chete ine PTFE lining ndiyo inoita kuti corrosion-resistant density metres dzikwanise kugadziriswa nemakemikari pasi pe acetyl chloride continuously exposure.
Kuongororwa kwemhando yebatch hakugone kuita kuti pave nekutarisa kwemakemikari panguva chaiyo mukugadzirwa kwelinalyl acetate. Kunonoka kuona zvinhu zvisina kujairika kunotungamira mukuwedzera kweacetyl chloride uye kuwedzera kwehydrogen chloride, zvichikonzera kushaikwa kwemunhuwi. Kusapatsanurwa kwakakwana kwechikamu panguva yekudistilla kunokonzera kuti chikafu chisina kugadziriswa chisvibise chigadzirwa, zvichikanganisa kutarisa kweacetyl chloride feed rate uye kuderedza kushandurwa kwezvinhu zvisina kugadzirwa.
Masisitimu ekugadzirisa akasimba anokanganisa kutaurirana kweRS485 mumamita ehuwandu hwemaindasitiri uye anokanganisa kubatanidzwa kwechiratidzo che4-20mA chakasimba kuti chidzore maitiro. Kusagadzikana kwechiratidzo nguva dzose kunotadzisa kutarisa maitiro nguva dzose uye kuona zvinhu zvisina kujairika, kuchideredza kubudirira kwekubudirira kwekugadzira uye kuchidzivisa kutevedzera mitemo yemhando yelinalyl acetate.
Mabhenefiti ekubatanidza Inline Density Meters
Kudzora huwandu hwemagetsi panguva chaiyo kunoita kuti vharuvhu ishande otomatiki panguva yekupatsanurana, zvichiwedzera goho relinalyl acetate neanopfuura 30% zvichienzaniswa nenzira dzinoshandiswa nebatch-based. Inline metres inokurumidza kuratidza acetyl chloride overdosage, ichidzivirira kuumbwa kweHCl yakawandisa uye ichichengetedza kudzora kwakanaka kwe chloride hydrogen kunhuhwirira muzvigadzirwa zveperfume. Cylindrical density metres ine Hastelloy bodies uye PTFE lining inodzivirira acetyl chloride corrosion, ichitsigira kutarisa kwenguva refu kwemakemikari mukugadzirwa kwelinalyl acetate. RS485 ne 4-20mA signals zvinopa data rakasimba uye rakarurama kune central PLC kana DCS systems pasi pemamiriro emakemikari akasimba. Kuenderera mberi kwe inline feedback kunowedzera kushandurwa kwefeed linalool ne acetyl chloride, kuderedza marara ezvigadzirwa mukugadzirwa kwe ester uye kuramba kuchivandudza kuchena kwezvinobuda kupfuura 95%. Kutarisa otomatiki, kunoteverwa kwehuwandu kunotsigira kutevedzera GB 29985-2013 quality standards ye linalyl acetate, kunyangwe mukuita uchishandisa anhydrous organic solvents.
Kumbira mutengo weLonnmeter inline density meter kuti ugadzirise esterification reaction control ne density metres mu linalyl acetate synthesis. Iva nechokwadi chekuti acetyl chloride feed rate inotarisirwa kudzivirira acetyl chloride overdose uye chloride hydrogen energy isingadiwe muzvishandiso zveperfume.
