Synthesis of barium alkylbenzene sulfonate and its behavior as a flow improver for crude oil
نویسندگان
چکیده
The low flow characteristics of heavy oil have brought many challenges to its exploitation. Looking for a cost-effective crude improver reduce the viscosity is currently most important challenge. Small-molecule improvers meet above requirements and become an ideal target oilfield production. In this article, three kinds barium salts alkylbenzene sulfonates with different lengths alkyl chains were synthesized from sulfonic acid hydroxide. Among them, reduction effect dodecylbenzenesulfonate (BaDBS) best as dosage 900 mg/L, rate 89.0%, pour point reduced by 5 °C. Optical microscopy revealed eutectic saturated hydrocarbon in oil. FTIR DSC used research mechanism small-molecule

Low Temperature Rheological Behavior of Umbarka Waxy Crude and Influence of Flow Improver
L’objet de cette étude est de déterminer les caractéristiques du brut paraffinique d’Umbarka, avec et sans additif pour l’amélioration de l’écoulement, à savoir, l’écoulement à basse température, le point d’écoulement, et les données rhéologiques. Les caractéristiques rhéologiques du brut font apparaître un comportement d’écoulement pseudoplastique avec une limite élastique non newtonienne ains...

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 Surfactant Tail Structure on Phase Behavior of Branched and Linear Alkylbenzene Sulfonate in Water and Oil Ternary Systems
Systematic investigations into the phase behavior of a ternary system of linear alkyl benzene sulfonate (LAS) or branched alkyl benzene sulfonate (BAS) in oil (corn or olive oil) and water were carried out. The study showed that there is a relationship between the surfactants’ chemical structure, aggregation properties, and the formation of micelles. The aggregation properties were dramatically...
متن کاملEffect of Crude Soybean Oil Sediment as a Substitute for Refined Soybean Oil in Broiler Diet
Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment gr...
