I-BFRL SP-5220 ihlangabezana njani ngokuchanekileyo nemigangatho yokunyibilikisa eyenziweyo yoshishino lwe-petrochemical?

Yintoni iSimulated Distillation? Kutheni "Kunzima Ukuyenza"?

Kuhlalutyo lweemveliso ezahlukeneyo ze-petroleum fraction kwishishini le-petrochemical, ukusasazwa kobubanzi bokubilisa luphawu oluphambili lokulinganisa umgangatho wemveliso kunye nokukhokela ulawulo lwenkqubo. Nangona iindlela zemveli zokunyibilikisa zilula, zinengxaki yexesha elide, ukusetyenziswa okuphezulu kwesampulu, kunye nokungaphindaphindeki kakuhle, okwenza zinganeli kwiimfuno zanamhlanje zokufumanisa ngokukhawuleza kwemizi-mveliso.

Ngoko ke, kwavela i-distillation eyenziwe ngendlela efanayo. I-NB/SH/T 0558-2016 esemgangathweni yaseTshayina ibeka iimfuno ezingqongqo kwezi mpawu: ukusuka ekunyukeni kobushushu obuphezulu kunye noyilo lwe-cold-point ukuya kwi-baseline drift ≤1% FS/h, ikhrayitheriya nganye ivavanya ukusebenza kokwenyani kwesixhobo. I-BFRL SP-5220 ihlangabezana njani nezi nkcukacha nganye nganye ngokuchanekileyo?

Umgaqo weNdlela

Indlela yokunyibilikisa eyenziwe ngokulinganisa ayilinganisi ngokuthe ngqo ngokwendawo yencochoyi ye-chromatographic nganye, kodwa kuqala imisela ukuhambelana "kwexesha lokugcina-indawo yokubila", emva koko izilayi kwaye ziqokelele i-chromatogram yesampuli ecaleni kwexesha. Ipesenti yokuhamba eqokelelweyo iguqulwa ibe kubushushu obuhambelanayo, ngaloo ndlela ifumana ukusasazwa kwendlela yokubila kwesampuli. Ngamafutshane, isebenzisa i-chromatography "ukulinganisa" inkqubo yokunyibilikisa ebonakalayo.

Nangona kunjalo, le ndlela inika imfuno ephezulu kakhulu kwisixhobo:

1. I-calibration curve kufuneka ihlale izinzile—Naluphi na utshintsho oluncinci kubudlelwane bexesha lokugcina kunye namanqaku okubila kuya kubangela ukuphambuka kwiziphumo zamanqaku okunyibilikisa.

2. I-chromatogram yeoyile esetyenzisiweyo kufuneka iqhubeke—nakuphi na ukuphazamiseka kwencopho, umsila, okanye impendulo engaqhelekanga ibonisa ingxaki yenkqubo.

3. Ii-algorithms zesoftware kufuneka zibekwe emgangathweni—ukuhlanganiswa kwezilayi, ukuguqulwa kobushushu, kunye nokufakelwa kweendawo zokunyibilikisa zonke kufuneka zilandele ngokungqongqo umgangatho we-NB/SH/T 0558.

Ngoko ke, inkqubo yokunyibilikisa eyenziwe ngokulinganisa ifaneleke ngokwenene kufuneka ngaxeshanye ihlangabezane nemigangatho yolawulo lwesekethe yegesi, ulawulo lobushushu, ulungelelwaniso lwesixhobo sokubona, kunye ne-algorithms yesoftware. I-Beifen Ruilili SP-5220 yenzelwe kanye le njongo.

IiChromatograms zokufumanisa kunye neziphumo

1)Ulwalamano lokulinganisa ixesha lokugcina ixesha kunye nokubila

Njengoko kubonisiwe kuMfanekiso 1. Ubudlelwane bokulinganisa ixesha lokugcinwa kunye nokubila, i-curve ye-retention time-boiling point curve esekwe kwindawo eqhelekileyo ye-Ortho alkanes iyaqhubeka kwaye ine-monotonicity elungileyo, esebenza njengesiseko sokuguqulwa kobushushu be-distillation eyenziwe ngendlela efanayo.

1)I-Chromatogram esemgangathweni ye-C5–C44

Kwi-chromatogram yesampulu eqhelekileyo, ulungelelwaniso lwe-elution lwenxalenye nganye lucacile, kwaye usasazo lwencopho luhambelana nolwalamano lokulinganisa, oluxhasa ukuguqulwa koluhlu lokubilisa lwesampulu olulandelayo.

1)I-Chromatogram ye-Reference Peak Correlation kunye ne-Reference Oil

I-reference peak correlation kunye ne-reference oil chromatogram zingasetyenziselwa ukuqinisekisa imeko yokusebenza kwendlela. I-chromatogram ibonisa ukuba indawo ye-reference peak inolwalamano olubonakalayo nokusasazwa kwesampulu, kwaye i-reference oil ibonisa uphawu lokusasazwa oluqhubekayo kuluhlu olupheleleyo lokubila.

Umfanekiso 4 i-chromatogram yeoyile ebhekisayo

1)Isishwankathelo seziphumo zeoyile ezibhekiselele kuzo

Ngokusekelwe kwiphepha leziphumo zokuqala, idatha ephambili yendawo yokunyibilikisa iioyile zesalathiso yile ilandelayo. Onke amaxabiso alinganisiweyo kwindawo nganye angaphakathi koluhlu oluvumelekileyo oluhambelana nexabiso ekujoliswe kulo.

Isiphelo sovavanyo

Ukudibanisa i-calibration curve, i-standard sample chromatogram, i-reference peak correlation, i-reference oil chromatogram, kunye ne-reference oil result table iqinisekisa ukuba iziphumo zovavanyo zesixhobo zigubungela ubungqina obubalulekileyo obufunekayo ekusebenzeni okuqhelekileyo kwendlela yokunyibilikisa eyenziwe ngokulinganisa:

✔ I-curve yokulinganisa ixesha lokugcina-ukubila kwe-boiling point iyaqhubeka, inika isiseko sokuguqulwa kobushushu.

✔ Isampulu eqhelekileyo ye-C5–C44 ibonisa ulungelelwaniso olucacileyo lwesisombululo, oluxhasa ukulinganiswa kwendlela.

✔ Ukusasazwa kwe-chromatogram yeoyile esetyenzisiweyo kuyinto eqhelekileyo, okuvumela ukufunyanwa kwesignali kulo lonke uluhlu lokubila.

✔ Iziphumo eziphambili ze-distillation kwi-oyile esetyenzisiweyo zonke ziwela kuluhlu oluvumelekileyo, kunye neziphumo ezipheleleyo.

Phantsi kwendlela eqhelekileyo ye-NB/SH/T 0558-2016, i-Beifen Ruili SP-5220 Gas Chromatograph inika inkxaso yohlalutyo esebenzayo nethembekileyo kubasebenzisi kwicandelo le-petrochemical, ixhaswa yidatha eqinileyo kunye neenkqubo zendlela ezimiselweyo.
