Demulsification of crude oil-in-water emulsions by means of fungal spores
The present feature describes for the first time the application of spores from Aspergillus sp. IMPMS7 to break out crude oil-in-water emulsions (O/W). The fungal spores were isolated from marine sediments polluted with petroleum hydrocarbons. The spores exhibited the ability to destabilize different O/W emulsions prepared with medium, heavy or extra-heavy Mexican crude oils with specific gravi...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...
Effect of the Structure of Commercial Poly(ethylene Oxide-b-propylene Oxide) Demulsifier Bases on the Demulsification of Water-in-crude Oil Emulsions: Elucidation of the Demulsification Mechanism
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 ...
متن کاملexperimental breaking of water/oil emulsions aimed at development of a water separation bacterial process in oil industries
microbial demulsifiers represent a potentially important product for the petroleum industry due to their specific modes of action, relative ease of preparation, biodegradability and low toxicity. an extracellular demulsifier, capable of the rapid break up of model multiple water-crude oil emulsions was obtained from the bacterial isolate ochrobactrum anthropi ripi5-1. demulsifying activity of t...
