Kodi BFRL SP-5220 imakwaniritsa bwanji molondola miyezo yoyeretsera yomwe imayesedwa yamakampani opanga mafuta?

Kodi Simulated Distillation ndi chiyani? N’chifukwa chiyani “N’zovuta Kuchita”?

Pofufuza zinthu zosiyanasiyana za mafuta mumakampani opanga mafuta, kugawa kwa malo ophikira ndi chizindikiro chofunikira poyesa ubwino wa zinthu ndikuwongolera njira zowongolera. Ngakhale njira zachikhalidwe zoyeretsera zinthu zimakhala zosavuta, zimakhala ndi nthawi yayitali, zimagwiritsidwa ntchito kwambiri, komanso sizingabwerezedwenso, zomwe zimapangitsa kuti zisakwanire zosowa zamakono zodziwika mwachangu.

Motero, kusungunuka koyeserera kunabuka. Muyezo wa ku China wa NB/SH/T 0558-2016 umakhazikitsa zofunikira zolimba pazizindikiro izi: kuyambira kukwera kwa kutentha kwambiri ndi kapangidwe ka malo ozizira mpaka kusuntha kwa baseline ≤1% FS/h, muyezo uliwonse umayesa magwiridwe antchito enieni a chipangizocho. Kodi BFRL SP-5220 imakwaniritsa bwanji zofunikirazi chimodzi ndi chimodzi molondola?

Mfundo Yoyendetsera Njira

Njira yoyeserera yoyeretsera siiwerengera mwachindunji malinga ndi dera la chromatographic peak, koma choyamba imakhazikitsa kulumikizana kwa "nthawi yosungira-kuwira" nthawi, kenako imaduladula ndikusonkhanitsa chromatogram ya chitsanzo motsatira nthawi. Chiwerengero cha kuyenda kwa madzi chimasinthidwa kukhala kutentha koyenera, motero kupeza kufalikira kwa njira yowira ya chitsanzo. Mwachidule, imagwiritsa ntchito chromatography "kutsanzira" njira yoyeretsera thupi.

Komabe, njira iyi imafuna kwambiri chida:

1. Mzere wokhotakhota uyenera kukhala wokhazikika—Kusintha kulikonse pang'ono kwa ubale wa nthawi yosungira ndi kuwira kumabweretsa kusiyana kwa zotsatira za distillation point.

2. Chromatogram ya mafuta ofunikira iyenera kukhala yopitilira—Kusokonezeka kulikonse kwa nsonga, mchira, kapena kuyankha kosayenera kumasonyeza vuto la dongosolo.

3. Ma algorithm a mapulogalamu ayenera kukhala ofanana—kuphatikiza magawo, kusintha kutentha, ndi kulowetsedwa kwa malo oyeretsera zonse ziyenera kutsatira mosamalitsa muyezo wa NB/SH/T 0558.

Chifukwa chake, makina oyeretsera oyeserera bwino ayenera kukwaniritsa nthawi yomweyo miyezo yowongolera mpweya, kuwongolera kutentha, kulumikizana kwa detector, ndi ma algorithms a mapulogalamu. Beifen Ruilili SP-5220 idapangidwa moyenera pachifukwa ichi.

Kuzindikira Ma Chromatogram ndi Zotsatira

1)Ubale wowerengera nthawi yosungira ndi kuwira kwa nthawi

Monga momwe zasonyezedwera mu Chithunzi 1. Ubale wowerengera nthawi yosungira ndi kuwira, nthawi yosungira ndi kuwira yomwe imakhazikika pa mfundo yokhazikika ya Ortho alkanes ndi yopitilira ndipo imakhala ndi kusinthasintha kwabwino, komwe kumagwira ntchito ngati maziko a kusintha kwa kutentha kwa distillation.

Chithunzi 1 Ubale wowerengera nthawi yosungira ndi kuwira kwa mfundo

1)C5–C44 Chromatogram Yokhazikika

Mu chromatogram yokhazikika ya chitsanzo, dongosolo la elution la gawo lililonse limakhala lomveka bwino, ndipo kugawa kwapamwamba kumagwirizana ndi ubale wa calibration, kuthandizira kusintha kwa zitsanzo zotentha pambuyo pake.

Chithunzi 2 C5–C44 Chromatogram Yokhazikika

1)Kugwirizana kwa Peak ndi Chromatogram ya Mafuta Othandizira

Chromatogram ya reference peak correlation ndi reference oil chromatogram zingagwiritsidwe ntchito kutsimikizira momwe njirayo ikugwirira ntchito. Chromatogram ikuwonetsa kuti malo a reference peak ali ndi mgwirizano wodziwika ndi kugawa kwa zitsanzo, ndipo mafuta ofotokozera amasonyeza kugawa kosalekeza pamlingo wonse wowira.

Chithunzi 3 chikugwirizana ndi kuchuluka kwa nthawi yodziwika

Chithunzi 4 cha chromatogram ya mafuta ofunikira

1)Chidule cha Zotsatira za Mafuta Ofunikira

Kutengera ndi tsamba loyambirira la zotsatira, deta yofunika kwambiri ya malo oyeretsera mafuta ofunikira ndi iyi. Mitengo yonse yoyezedwa pa mfundo iliyonse ili mkati mwa mulingo wovomerezeka wofanana ndi mtengo womwe mukufuna.

Chithunzi 5 Tsamba la zotsatira za mapulogalamu

Mapeto a Mayeso

Kuphatikiza ma calibration curve, standard sample chromatogram, reference peak correlation, reference oil chromatogram, ndi reference oil results table zimatsimikizira kuti zotsatira za mayeso a chipangizochi zikuphimba umboni wofunikira wofunikira kuti njira yoyeretsera yoyeserera igwire ntchito bwino:

✔ Mzere wowerengera nthawi yosungira ndi kuwira nthawi zonse umakhala wokhazikika, zomwe zimapangitsa kuti kutentha kusinthe.

✔ Chitsanzo chokhazikika cha C5–C44 chikuwonetsa dongosolo lomveka bwino la elution, lothandizira kuwerengera njira.

✔ Kugawa kwa chromatogram ya mafuta ofunikira ndi kwabwinobwino, zomwe zimathandiza kuti chizindikiro chizipezeka m'malo onse otentha.

✔ Zotsatira zazikulu za distillation ya mafuta ofunikira onse ali mkati mwa mulingo wovomerezeka, ndipo zotsatira zake zonse zimatuluka.

Motsatira njira yokhazikika ya NB/SH/T 0558-2016, Beifen Ruili SP-5220 Gas Chromatograph imapereka chithandizo chodalirika komanso cholondola kwa ogwiritsa ntchito m'munda wa petrochemical, mothandizidwa ndi deta yolimba komanso njira zokhazikika.
