Emqhudelwaneni oshubile wezimboni ze-petrochemical kanye namakhemikhali, amakholomu e-vacuum distillation, okokusebenza okuhlukanisayo okuyinhloko, kunethonya kumthamo wokukhiqiza, ikhwalithi yomkhiqizo, kanye nezindleko zenkampani ngokusebenza kahle nokusebenza ngokunemba kokulawula. Ukushintshashintsha kokuminyana kokuphakelayo noma ukusebenza kahle kokuhlukaniswa kuholela ekwandeni kwamathuba okwehluleka kwenqwaba nokusebenza okungasebenzi kahle.
Enqubweni yokukhishwa kwe-vacuum distillation ngaphansi kwengcindezi encishisiwe, amamitha okuminyana okusemgqeni asetshenziswa ekuhlolweni komkhiqizo ngemuva kokukhishwa kwe-distillation nokuhlukaniswa ngokujwayelekile. Avamise ukufakwa endaweni ephuma ngaphansi kwekholomu, eduze kwendawo yokudonsa eseceleni, noma epayipini le-reflux eliphezulu. Injongo yabo eyinhloko ilele ekuqapheni ngesikhathi sangempela phezu kokuminyana, okuvumela ukulawula okunembayo kokusebenza kahle kokuhlukanisa kanye nekhwalithi yomkhiqizo ku-distillation kuyilapho kuthuthukisa ukusebenza kahle nezindleko zabasebenzi.
1. Izinselelo Ekulawuleni Ukuminyana Kwendabuko
1. Ukuvalwa Kwezisetshenziswa Ngenxa Yokulibaziseka Ukuhlolwa
Kumasampula okwenziwa okwenziwa ngesandla nokuhlaziya, ukuthola idatha yokuminyana kukholomu ye-vacuum distillation kuthatha imizuzu engama-20–60. Isimo sokuhlukaniswa kwesigaba segesi-uketshezi ngaphakathi kwekholomu asikwazanga ukulinganiswa nokulawulwa. Uma ukuminyana kokuphakelayo kushintshashintsha noma ukusebenza kahle kokuhlukaniswa kwehla, isilinganiso se-reflux noma amandla okushisa ayahluleka ukulungiswa ngesikhathi. Khona-ke kuholela ezingozini ezikhulayo zokuhluleka kwenqwaba kanye nokusebenza okungasebenzi kahle.
2. Ikhwalithi Enesici Ebangelwa Amaphutha Azenzela
Amaphutha okulinganisa imitha yokuminyana ngokubhalwa kwesihloko ngesandla noma elabhorethri akhuphukela ku-±5%, ehluleka ukuhlangabezana nezimfuneko ezinembayo zemikhiqizo ehlanzeke kakhulu njengophalafini wendiza noma izinyibilikisi zebanga lezemithi. Isibonelo, ukuchezuka kuwoyela wesisekelo sokuthambisa okungu-0.01 g/cm³ kungase kubangele ukungathotshelwa kwe-viscosity ngisho nokucutshungulwa kabusha kwayo yonke inqwaba.
Okubi nakakhulu, ukwehluleka ukuqapha ukuminyana kwesigaba se-aqueous kungabangela izigameko lapho imikhiqizo ifaka okuqukethwe okuthile kawoyela, okubangela ukuvalwa kwesistimu yokwelashwa kwamanzi omfula kanye nezingozi zokuphepha nezemvelo.
3. Izindleko Izicupho Cumulative Ukulahleka Okufihliwe
Izindleko zomsebenzi zokusampula okwenziwa ngesandla zingadinga izisebenzi ezizinikele ezi-2–3 ezisebenza amashifu amathathu, nezindleko zomsebenzi zonyaka ezingaphezu kwama-$300,000. Ukushintshashintsha kokuminyana kubangela amaphutha okuhlukanisa izingxenye, kumosheke amakhulu amathani kawoyela ongahluziwe minyaka yonke. Ukulungiswa okuvamile kumapharamitha wenqubo kufinyeza isikhathi sokuphila kwekholomu ne-reboiler, okwandisa izindleko zokulungisa ngo-15%–20%.
2. Ukwethulwa kwe-Intelligent Inline Density Meter
Ukuthatha i-Lonnmeterimitha yokuminyana emgqeninjengesibonelo,i-ultrasonicdenindawoamamithaukulinganisa isikhathi sokusabalala kwamagagasi omsindo ukubala isivinini somsindo, lapho ukugxila koketshezi noma ukuminyana kutholwa khona. Lobu buchwepheshe bungabonisa ukuminyana kokumiswa, ngokunemba okungu-±0.0005 g/cm³ kanye nezikhathi zokuphendula ngokushesha, kushintsha ngokuphelele izindlela zokuqapha ezivamile.
1. Ukuqapha Kwesikhathi Sangempela Kuyo Yonke Inqubo
Okuphakelayo End:Ukufaka imitha yokuminyana epayipini ngaphambi kokuba uwoyela ongahluziwe ungene kukholomu ye-vacuum kuvumela ukulandelelwa kwesikhathi sangempela kokuguquguquka kokuminyana kokuphakelayo (isb, ngesikhathi sokucwengisiswa ngokuhlanganyela kwamafutha aluhlaza asindayo nalula). Ihlanganisa ne-Distributed Control System (DCS) ukuze ilungise ngokuzenzakalelayo izilungiselelo ze-vacuum kanye nemithwalo yokupholisa ephezulu yekholomu, iqinisekise ukusebenza kahle kokukhishwa kwe-distillation okuzinzile.
Ukuphela kokwehlukana:Imitha yokuminyana endaweni yokuphuma kwesigaba sikawoyela iqapha ngamandla ukuminyana kukawoyela we-distillate. Uma amanani echezuka kokuthile (isb, 0.85 g/cm³ ± 0.005), ilungisa ngokuzenzakalelayo isilinganiso se-refluxtominimizeukulahlekelwa izinga.
I-Drainage End:Ukusetha i-threshold yokuminyana (isb., 0.9 g/cm³ icupha i-alamu) endaweni yokukhipha i-aqueous phase ivimbele ukuthuthwa kukawoyela, inciphise imithwalo yokuhlanza amanzi angcolile angaphansi komfula kanye nemfucumfucu yezinto ezingavuthiwe.
2. Utshalomali Lwesikhathi Esifushane&Inani Lesikhathi Eside
1. Ukonga Izindleko
Izindleko Zabasebenzi:Ukuqeda ukonga kwamasampula wabasebenzi abazinikele$250,000–400,000 ngonyaka.
Impahla eluhlaza Izindleko:Ukulawula ukuminyana okuthuthukisiwe kunciphisa ukusetshenziswa kukawoyela ongahluziwe ngo-0.3%–0.5%.Take 1 milibhubesi amathanipamarosicula as a example, costsi-avings kwe raw mai-terials go beyphezu $5 million.
Izindleko Zamandla:Ukulawula okuzenzakalelayo kunciphisa isikhathi sokungasebenzi kwemishini, kwehlisa ukusetshenziswa kwesitimu ngo-8%–12%, konga$Izigidi ezingu-1–1.5 ezindlekweni zamandla ngonyaka.
2. Ukusebenza Ngempumelelo
Imijikelezo ye-distillation eyodwa ifinyezwa ngo-10% -15%,whih isequalkuannual ikhaphaidolobha ofi-distillation encane-to-medium-sizeikholomu.
Ukwehluka kokuminyana kweqoqo kuye kwehla kusuka ku-3.5% kuya ku-0.8%, okuthuthukisa kakhulu ukwethenjwa kwamakhasimende emikhiqizweni ephezulu.
3. Ukuthuthukiswa Kokuhambisana Nokuphepha
-Ihlangabezana nesistimu yokuphatha ikhwalithi ye-ISO 9001 kanye namazinga okuphepha e-OSHA, ihlinzeka ngochungechunge oluphelele lokulandelelwa kwedatha lwesikhathi sangempela lwe-FDA, i-EPA, nokunye ukuhlola okulawulwayo.
Isilinganiso esingathintana nabo sigwema ukuchayeka kubantu kuzinga lokushisa eliphezulu, imidiya ephezulu, ukwehlisa izingozi zokusha noma ubuthi futhi siqondanise nezimfuneko zesimanje ze-ESG (Environmental, Social, Governance).
When yiyoreferSto precision kweukukhiqizwa kwezimboni, imitha ye-inline density akuyona amonitor merelykodwa ihabhu elibucayicombphakathig izwel-isikhathi datekanye nokwenza ngcono. Ezinkampanini eziphishekela uguquko oluhlakaniphile, ukukhetha imitha yokuminyana esemgqeni kusho ukuhlela kabusha ingqondo yokukhiqiza ngokunemba.reyadinigs, ukubamba umkhawulo wokuncintisana ekuguquleni kabusha imboni.
Thola isisombululo sokuqapha ukuminyana okwenziwe ngokwezifiso ukwenza i-vacuum distillation yakhoikholomuibhentshimakhi yokusebenza kahle kweera ofimboni ehlakaniphile! Chofoza ukuze uxhumane nathi futhi uvule ukuncintisana okuyinhloko.
