I-BFRL SP-5220 ihlangabezana kanjani ngokunembile nezindinganiso zokuhluza ezilingisiwe zemboni yamakhemikhali kaphethroli?

Kuyini i-Simulated Distillation? Kungani “Kunzima Ukuyenza”?

Ekuhlaziyweni kwemikhiqizo ehlukahlukene yezingxenye zephethiloli embonini yamakhemikhali kaphethiloli, ukusatshalaliswa kwebanga lokubilisa kuyisibonakaliso esibalulekile sokulinganisa ikhwalithi yomkhiqizo kanye nokuqondisa ukulawulwa kwenqubo. Nakuba izindlela zendabuko zokuhluza zilula, zihlushwa isikhathi eside, ukusetshenziswa kwamasampula aphezulu, kanye nokungaphindaphindeki kahle, okwenza zinganele izidingo zanamuhla zokutholwa okusheshayo kwezimboni.

Ngakho-ke, kwavela ukucwiliswa okulingisiwe. Izinga elijwayelekile laseShayina i-NB/SH/T 0558-2016 libeka izidingo eziqinile zalezi zinkomba: kusukela ekukhuphukeni kwezinga lokushisa eliphezulu kanye nomklamo we-cold-point kuya ekushayweni kwesisekelo ≤1% FS/h, indinganiso ngayinye ihlola ukusebenza kweqiniso kwethuluzi. I-BFRL SP-5220 ihlangabezana kanjani nalezi zincazelo ngayinye ngokunemba?

Isimiso Sendlela

Indlela yokuhluza eyenziwe ngokulingisa ayilinganisi ngokuqondile indawo ye-chromatographic peak ngayinye, kodwa kuqala isungula ukuxhumana "kwesikhathi sokugcina-iphuzu lokubila", bese inquma bese iqoqa i-chromatogram yesampula nge-axis yesikhathi. Iphesenti lokugeleza elihlanganisiwe liguqulwa libe izinga lokushisa elihambisanayo, ngaleyo ndlela kutholakale ukusatshalaliswa kwendlela yokubila kwesampula. Kalula nje, isebenzisa i-chromatography "ukulingisa" inqubo yokuhluza ngokomzimba.

Kodwa-ke, le ndlela ibeka izidingo eziphezulu kakhulu kuthuluzi:

1. Ijika lokulinganisa kumele lizinze—Noma yikuphi ukuzulazula okuncane ebudlelwaneni besikhathi sokugcina kanye namaphuzu okubila kuzobangela ukuphambuka emiphumeleni yamaphuzu okuhluzwa.

2. I-chromatogram yamafutha okubhekisela kumele iqhubeke—noma yikuphi ukuhlanekezela okuphezulu, umsila, noma impendulo engavamile kubonisa iphutha lesistimu.

3. Ama-algorithm esofthiwe kumele alinganiswe—ukuhlanganiswa kwezingcezu, ukuguqulwa kwezinga lokushisa, kanye nokuhlanganiswa kwephuzu lokuhluza kumele kulandele ngokuqinile indinganiso ye-NB/SH/T 0558.

Ngakho-ke, uhlelo lokuhluza olulingiswayo olufaneleke ngempela kumele luhlangabezane ngasikhathi sinye nezindinganiso zokulawula isekethe yegesi, ukulawula izinga lokushisa, ukulingana kwe-detector, kanye nama-algorithms esofthiwe. I-Beifen Ruilili SP-5220 yenzelwe ngqo le njongo.

Ama-Chromatogram Okuthola kanye Nemiphumela

1)Ubudlelwano bokulinganisa iphuzu lokugcina isikhathi nokushisa

Njengoba kuboniswe kuMfanekiso 1 Ubudlelwano bokulinganiswa kwephuzu lokugcina isikhathi nokubila, ijika lephuzu lokugcina isikhathi nokubila elisungulwe endaweni ejwayelekile yama-alkanes e-Ortho liyaqhubeka futhi linokuhlukahluka okuhle, okusebenza njengesisekelo sokuguqulwa kokushisa kwe-distillation okulingisiwe.

Umfanekiso 1 Ubudlelwano bokulinganiswa kwamaphuzu okugcina isikhathi nokubila

1)I-Chromatogram Ejwayelekile ye-C5–C44

Ku-chromatogram yesampula ejwayelekile, ukuhleleka kokuxazulula kwengxenye ngayinye kucacile, futhi ukusatshalaliswa okuphezulu kuhambisana nobudlelwano bokulinganisa, okusekela ukuguqulwa kwebanga lokubilisa kwesampula okulandelayo.

Umfanekiso 2 C5–C44 I-Chromatogram Ejwayelekile

1)I-Chromatogram Yokuxhumana Okukhulu Kokubhekisela kanye Ne-Chromatogram Yamafutha Okubhekisela

I-reference peak correlation kanye ne-reference oil chromatogram ingasetshenziswa ukuqinisekisa isimo sokusebenza kwale ndlela. I-chromatogram ikhombisa ukuthi indawo ye-reference peak inobuhlobo obubonakalayo nokusatshalaliswa kwesampula, futhi uwoyela obhekiselayo ubonisa isici sokusabalalisa okuqhubekayo kulo lonke ibanga lokubila.

Umfanekiso 3 ukuhambisana kwenani eliphakeme lokubhekisela

Umfanekiso 4 i-chromatogram yamafutha abhekiselayo

1)Isifinyezo Semiphumela Yamafutha Abhekiselayo

Ngokusekelwe ekhasini lokuqala lemiphumela, idatha ebalulekile yamaphuzu okuhluzwa kwamafutha okubhekisela yilena elandelayo. Wonke amanani alinganisiwe endaweni ngayinye angaphakathi kobubanzi obuvunyelwe obuhambisana nenani eliqondiwe.

Umfanekiso 5 Ikhasi lemiphumela yesofthiwe

Isiphetho Sokuhlola

Ukuhlanganisa ijika lokulinganisa, i-chromatogram yesampula ejwayelekile, ukuhlangana kwe-reference peak, i-chromatogram yamafutha okubhekisela, kanye nethebula lemiphumela yamafutha okubhekisela kuqinisekisa ukuthi imiphumela yokuhlola yethuluzi imboza ubufakazi obubalulekile obudingekayo ekusebenzeni okuvamile kwendlela yokucwilisa eyenziwe ngendlela yokulingisa:

✔ Ijika lokulinganisa isikhathi sokugcina – iphuzu lokubila liyaqhubeka, linikeza isisekelo sokuguqulwa kwezinga lokushisa.

✔ Isampula ejwayelekile ye-C5–C44 ibonisa uhlelo olucacile lokuxazulula, olusekela ukulinganiswa kwendlela.

✔ Ukusatshalaliswa kwe-chromatogram yamafutha okubhekisela kuvamile, okuvumela ukutholwa kwesignali kulo lonke ibanga lokubila.

✔ Imiphumela ebalulekile yamaphuzu okuhluzwa kwamafutha okubhekisela kuwo wonke awela ngaphakathi kobubanzi obuvunyelwe, kanye nomphumela ophelele.

Ngaphansi kwendlela ejwayelekile ye-NB/SH/T 0558-2016, i-Beifen Ruili SP-5220 Gas Chromatograph inikeza ukwesekwa kokuhlaziya okusebenzayo nokuthembekile kubasebenzisi emkhakheni we-petrochemical, okusekelwa idatha eqinile kanye nezinqubo zendlela ezijwayelekile.
