Tsarin danyemasu rage yawan maiya dogara ne akan ka'idar juyewar ...
Man fetur mai yawa yana faruwa ne a lokacin samar da mai da kuma tace shi. Yawancin man fetur na duniya ana samar da shi ne ta hanyar emulsified. Man fetur mai narkewa ya ƙunshi aƙalla ruwa biyu da ba za a iya narkar da su ba, inda ɗaya ke warwatse a matsayin ɗigon ruwa mai ƙanƙanta (kimanin diamita 1 mm) wanda aka rataye a ɗayan.
Yawanci, ɗaya daga cikin waɗannan ruwayen ruwa ne, ɗayan kuma mai ne. Ana iya watsa man a cikin ruwa kaɗan, yana samar da mai a cikin ruwa (O/W), inda ruwa shine matakin ci gaba kuma mai shine matakin warwatse. Akasin haka, idan mai shine matakin ci gaba kuma ruwa ya warwatse, yana samar da ruwa a cikin mai (W/O). Yawancin mai na ɗanyen mai suna na nau'in na ƙarshe.
A cikin 'yan shekarun nan, bincike kan hanyoyin rage yawan man fetur ya mayar da hankali kan cikakken lura da yadda ake hada ɗigon ruwa da kuma tasirin masu rage yawan man fetur a kan ilimin halittar fata. Duk da haka, saboda sarkakiyar hulɗar da ke tsakanin sinadaran da ke haifar da sinadarin demulsifier da kuma sinadarin emulsion, duk da bincike mai zurfi, har yanzu babu wata ka'ida guda ɗaya kan tsarin rage yawan man fetur.
Akwai hanyoyi da dama da aka yarda da su sosai:
1. Motsi na ƙwayoyin halitta: Kwayoyin halitta suna maye gurbin emulsifiers a mahaɗin, suna lalata emulsion ɗin.
2. Lalacewar wrinkles: Nazarin ƙananan ƙwayoyin cuta ya nuna cewa emulsions na W/O suna da layukan ruwa biyu ko fiye da ɗaya da aka raba ta hanyar zoben mai. A ƙarƙashin dumamawa, tashin hankali, da kuma aikin cirewar mai, waɗannan layukan suna haɗuwa, suna haifar da haɗuwar ɗigon ruwa.
Bugu da ƙari, binciken cikin gida kan tsarin emulsion na O/W ya nuna cewa ingantaccen na'urar cire ruwa dole ne ta cika waɗannan sharuɗɗan: ƙarfin aikin saman, kyakkyawan juriyar ruwa, isasshen ƙarfin flocculation, da ingantaccen aikin haɗin gwiwa.
Ana iya rarraba demulsifiers bisa ga nau'ikan surfactant:
•Sinadaran Anionic: Sun haɗa da carboxylates, sulfonates, da polyoxyethylene fatty sulfates. Ba su da tasiri sosai, suna buƙatar allurai masu yawa, kuma suna da saurin kamuwa da electrolytes.
•Ma'adanai masu rage yawan sinadarin cationic: Galibi gishirin ammonium na quaternary, masu tasiri ga mai mai sauƙi amma ba su dace da mai mai nauyi ko tsufa ba.
•Nonionic demulsifiers: Sun haɗa da tubalan polyethers da amines ko alcohols suka fara, alkylphenol resin block polyethers, phenol-amine resin block polyethers, silicone-based demulsifiers, ultra-high molecular weight demulsifiers, polyphosphates, modified block polyethers, da zwitterionic demulsifiers (misali, danyen mai demulsifiers bisa imidazoline).
