The article deals with the issues of improving quality highly watered well production fluid processing using chemical demulsifier reactants at crude oil facilities; analysis use Samotlor field has been made. presents results study effectiveness "Hercules 2202 grade A" and "SNPH-4460-2" demulsifiers in comparison indicators bottom water achieved presence used existing their optimal consumption d...

Water-in-crude oil emulsions are formed during petroleum production and asphaltenes play an important role in their stabilization. Demulsifiers are added to destabilize such emulsions,however the demulsification mechanism is not completely known. In this paper, the performances of commercial poly(ethylene oxide-b-propylene oxide) demulsifiers were studied using synthetic water-in-oil emulsions ...

Pada proses pemurnian minyak mentah di area Duri dilakukan pada fasilitas stasiun pengumpul umum. Stasiun ini melakukan bumi rata – 20.000 barel per hari dan air 250.000 barrel hari. dibutuhkan demulsifier untuk membantu pemurnian. Konsumsi saat sangat besar, dengan pemakaian sebesar 100ppm perhari. Hal menimbulkan biaya operasional yang cukup besar dalam hal dibanding jumlah produksi dihasilka...

High-viscosity crude oils from the Yablunivske field (Ukraine, Poltava region) have been studied. The were diluted with gas condensate to reduce viscosity, and then various demulsifiers added. It was established that it is expedient dilute oil heavy dehydrate PM-1441 brand A non-ionogenic demulsifier, based on block copolymers of ethylene propylene oxides. dewatering degree found be 95 %.

Nano-assisted inclusion separation of alkali metals from basic solutions was reported by inclusion-facilitated emulsion liquid membrane process. The novelty of this study is application of nano-baskets of calixcrown in the selective and efficient separation of alkali metals as both the carrier and the surfactant. For this aim, four derivatives of diacid calix[4]-1,2-crowns were synthesized, and...

Short-term production optimization of oil assets concerns routing decisions and equipment control settings that induce optimal steady-state operations. Typically, the are made on scale hours to days with aim maximizing short-term economic gains. Still an evolving field, this paper contributes by presenting a model solution strategy for sequencing operations over time drive system towards state,...
