Kulemera kwa API kwa Crude
Mphamvu yokoka ya API imagwira ntchito ngati "wothandizira wanzeru"—kudzera mu izi, titha kuzindikira zinthu zambiri zofunika zomwe zimakhudza mwachindunji zovuta za demulsification:
1. Kapangidwe Konse ka Mafuta Osaphikidwa ndi Kusinthasintha kwa Emulsion.
2. Kukhuthala kwa Mafuta Osaphikidwa ndi Kutentha Kofunikira Kogwiritsidwa Ntchito.
3. Mitundu ya Zinyalala Zosatha.
4. Malangizo a Kapangidwe ka Demulsifier. -
Mikhalidwe Yogwirira Ntchito
1. Kodi kutentha kwa ntchito zanu za mafuta kumadalira pati? (Kugwira ntchito kwa Demulsifier kungakhudzidwe ndi kutentha)2. Kodi mumagwiritsa ntchito zipangizo zotani zolekanitsa? (Mwachitsanzo, matanki okoka mphamvu yokoka, makina ochotsera madzi m'thupi pogwiritsa ntchito electrostatic dehydrators, ndi zina zotero, chifukwa zipangizo zosiyanasiyana zingafunike ma demulsifiers osiyanasiyana)3. Kodi mukufuna kuti njira yochotsera mulu wa madzi ichitike mwachangu bwanji? (Kuchotsa mulu wa madzi mwachangu kungafunike njira zinazake) -
Zofunikira Zapadera
Kodi zofunikira zanu zenizeni ndi ziti kuti muchepetse kusungunuka kwa madzi? (Mwachitsanzo, kuchuluka kwa madzi otsala mu mafuta osakonzedwa kapena kuchuluka kwa mafuta m'madzi otayira mutalekanitsidwa)Kodi mukufuna demulsifier kuti ikupatseninso ntchito zochotsera mchere kapena zochotsa tinthu tolimba?
Mlingo ndi Njira Yogwiritsira Ntchito？Kodi muli ndi ziyembekezo kapena zolepheretsa zilizonse zokhudzana ndi mlingo wa demulsifier? (Izi zikukhudzana ndi ndalama zogwirira ntchito komanso kusavuta kugwiritsa ntchito)
Ndipo tikasankha chosungunulira cha demulsifier, kwenikweni, chogwirira ntchito chimatha kuthetsa kwathunthu mu chosungunulira, ndipo tiyenera kuganizira kulemera kwa mamolekyulu, komwe kumakhudza liwiro la kufalikira mu ma crudes osiyanasiyana a API. Ndicho chifukwa chake API ndi yofunika.
Mwa kuphatikiza API Gravity ndi mfundo zina zofunika (BS&W, khalidwe la madzi (mchere), kutentha, mitundu ya zinthu zolimba zopangidwa, ndi zina zotero), Titha kupatsa makasitomala njira yochepetsera madzi yomwe yasinthidwa kukhala yokhazikika, yothandiza, komanso yotsika mtengo.
Kodi ma emulsion breakers athu amapangidwa bwanji?
Kutengera mphamvu ya API ya mafuta osaphika omwe akufuna (opepuka poyerekeza ndi olemera), BS&W (yosonyeza kuchuluka kwa zinthu zolimba), ndi momwe ntchito yochotsera mulu (kutentha, kupanikizika: ntchito zotentha kwambiri zimafuna kuti demulsifier ndi solvent yake zikhale ndi kukhazikika kwabwino kwa kutentha), ma demulsifier amasinthidwa motere:
Magulu ogwira ntchito okhala ndi manambala osiyanasiyana komanso kulemera kwa mamolekyu amasankhidwa ngati oyambitsa. Pansi pa mikhalidwe inayake, ma ratios osiyanasiyana (kuti asinthe mtengo wa HLB wa demulsifier—Hydrophilic-Lipophilic Balance) ndi ma sequences a PO (lipophilic head) ndi EO (hydrophilic head) amaphatikizidwa kuti apange maunyolo a polima a kutalika kosiyanasiyana (magawo ataliatali a unyolo amawonjezera lipophilicity ya molekyulu kapena hydrophilicity). Pambuyo pake, zosungunulira zokhala ndi kulemera koyenera kwa mamolekyu (zomwe zimatha kusungunula demulsifier kwathunthu, kuwonetsa kukhuthala koyenera popompa ndi jakisoni, kupewa emulsification yachiwiri kapena mvula, kukhala ndi ma flash point oyenera, ndikuwonetsetsa kuti chitetezo ndi chilengedwe ndi zabwino) zimasankhidwa kuti zitsirize kapangidwe ka demulsifier.
Kuti muwerenge zambiri, kodi ndi zinthu ziti zomwe ziyenera kuganiziridwa posankha zochotsera mafuta m'thupi?
Chiyambi cha malonda
▶ UBPro-411 imapangidwa ndi kupolisha ethylene oxide ndi propylene oxide m'malo osakanikirana pansi pa mkhalidwe wa alkaline pogwiritsa ntchito phenol resin, polybasic alcohol, polyethylene polyamine ngati choyambitsa.
▶ Zimasokoneza ma emulsions amadzi mu mafuta ndipo zimathandiza ngati gawo la njira zochotsera madzi ndi kuchotsa mchere m'mafuta ndi mafakitale ena ofanana nawo.
▶ Ikhoza kusakanizidwa ndi zosungunulira zosiyanasiyana kuti ipange demulsifier yosungunuka m'madzi/mafuta yokhala ndi zosakaniza zosiyanasiyana zogwira ntchito.
Pofuna kuthana ndi mavuto a kuchotsedwa kwa mafuta osaphika otentha kwambiri, mafuta olemera kwambiri komanso kuchotsedwa kwa mafuta osaphika kwambiri, kuchotsedwa kwa mafuta osaphika opangidwa ndi madzi opangidwa ndi emulsified, mainjiniya athu adapanga ma demulsifiers omwe ali ndi magwiridwe antchito abwino kwambiri ochotsa mchere m'madzi.
Mapulogalamu/Ntchito
▶ Sakanizani demulsifier mpaka kuchuluka koyenera ndi solvent yoyenera musanagwiritse ntchito (Monga: Aromatic Hydrocarbon), ikani kumapeto kwa payipi kapena ikani mu mzere wolowera wa thanki yolumikizidwa ya madzi osowa, kapena mu thanki yochotsera madzi ndi mafuta osakonzedwa kuti muchotse madzi osowa.
▶ Kuti muwonetsetse zotsatira zabwino kwambiri, muyenera kuyesa kaye pa demulsifier model musanagwiritse ntchito.
Zofunika:
Chotsukira mafuta ichi cha UBPro-411 chagwiritsidwa ntchito ku China komanso kum'mwera chakum'mawa kwa Asia, kuti athetse mavuto a kutentha kochepa, mowa wa methyl umawonjezeredwa ku U.BPro-411, mowa wa methyl umaipangitsa kukhala ndi mphamvu yochepa, zomwe zimapangitsa kuti ikhale yoopsa, koma mainjiniya athu odziwa bwino ntchito angatithandize pa izi, chonde titumizireni uthenga kuti mudziwe zambiri.

Kusamalira Koyenera
▶ Mlingo woyenera ndi 30 mpaka 100ppm, pomwe mayeso oyeserera amafunika kuti mupeze zotsatira zabwino.
▶ Ogwira ntchito onse ogwira ntchito imeneyi ayenera kuigwira ngati mankhwala a mafakitale, atavala zida zodzitetezera komanso kutsatira malangizo odzitetezera monga momwe zafotokozedwera mu Tsamba la Deta la Chitetezo cha Zinthuzo.
Kulongedza ndi Kusunga
▶ Yopakidwa mu ng'oma ya 200Litre kapena 1000 Liter IBC (Tote Tank).
▶ Sungani pamalo ouma komanso opumira bwino. Tsekani chidebecho. Sungani kutali ndi kutentha, zipsera ndi malawi. Sungani kutali ndi zinthu zosagwirizana. Tsatirani njira zotetezeka zosungiramo zinthu monga kuyika ma pallet, kulumikiza, kukulunga ndi/kapena kuyika zinthu m'mabokosi.

Zokhudza Demulsifier
Mu magawo otsiriza a kugwiritsa ntchito mafuta m'minda, ma emulsion a mafuta osakonzedwa nthawi zambiri amakhala machitidwe amafuta m'madzi (O/W), nthawi zambiri amakhala pamodzi ndi ma emulsion angapo ndi ma microemulsion. Madzi opangidwawo ali ndi makhalidwe angapo ovuta: madzi ambiri, madzi opanda mafuta ndi zinthu zodetsa, a mlingo wozama wa emulsification mu mafuta osakonzedwa okhala ndi madzi, ndi mavuto aakulu pakusowa madzi m'thupi.
Kuti tithetse mavutowa bwino, mtundu watsopano wa demulsifier ndi wofunikira. Demulsifier iyi iyenera kukhala ndi kapangidwe kosungunuka m'madzi, kolumikizidwa mwanzeru zimenezo ndi zosavuta kufalitsa mu mafuta osakonzedwa ndipo akuwonetsa kulola mpweya wabwino kulowa, zomwe zimathandiza kuchepetsa kuchuluka kwa mafuta m'madzi otayidwa mchere. Makamaka, zochotsa mphamvu za copolymer block akuwonetsedwa pachifukwa ichi. Kuonetsetsa kuti kuthamanga kwa madzi m'thupi mwachangu ndi zotsatira zabwino kwambiri za kusowa madzi m'thupi, kapangidwe ka mamolekyu a ma demulsifier awa kayenera kukhala ndi ndondomeko yoyenera ya block ndi kutalika kwa gawo la unyolo.

Ma demulsifier nthawi zambiri amaphatikiza zinthu zosungunuka m'madzi (monga fatty alcohol polyoxyethylene ether, triethanolamine) ndi zinthu zosungunuka m'mafuta (monga Basorol E 2032, TOMAC), ndipo zinthu zosungunuka monga aromatic solvents zimagwiritsidwa ntchito kuti ziwonjezere kusungunuka. Gawo lililonse limagwira ntchito polimbikitsa kutuluka kwa madzi m'maselo, kuletsa kukhazikika kwa emulsion komanso kulekanitsa gawo la madzi. Kukonza bwino njirayo kuyenera kudziwa kuphatikiza kwabwino kwambiri kudzera mu zoyeserera kutengera momwe emulsion imakhalira (monga kutentha ndi pH).
Ndikofunikira kuti ogwiritsa ntchito asankhe mitundu yoyenera kutengera mawonekedwe a emulsions yamafuta (monga mchere, kutentha, ndi kuchuluka kwa asphaltene)
