Gap between domestic and abroad technology is also compared. Advanced technology and experience are recommended. It is recommended that enhancing domestic technology, improving management, and taking the advantages of pipeline to reduce transportation cost, and building national wide pipeline system to increase competitiveness of domestic refined oils.
Logistics of refined oils includes three major functions (storage, transportation and distribution) and four minor functions (package, loading and unloading, processing and information processing ).
A bleaching technology is necessary when produce the refined oils, the methods of bleaching are difference, but the most general one is take the use of activated SBC (spent bleaching clay) for its absorption capability.
The extracting effects were observed. The test result shows that in the extraction process by using the two kinds of solvents, the extracting temperature can be reduced by about 30℃, the viscosity indexes of the refined oils can increase by 4-6 and the yield can be enhanced by 0.6%-3.0% in comparison with the traditional furfural extraction.
It is well known that volatile hydrocarbons such as benzene, toluene, and xylene, which are abundant in many refined oils, affect phytoplankton growth.
The experimental results of laser-induced fluorescence spectra of oils are presented. It is recommended that the ratio of fluorescence intensity at the highest peak wavelength to that at the second can be used for identification of oils. In measuring China crude and semi-refined oils, it is found that the differences of fluorescence intensity ratios can provide technical parameters for identifying oils with close peak wavelengths.
Sodium salt of dioctylsulfosuccinate (NaDOSS)is an anionic surfactant which is commer- cially manufactured in China.It is readily soluble in strong acids,refined oils,and forma- tion waters.Added into concentrated acidizing fluids instead of commonly used surfactants such as OP,ABS,and AS,it prevents oil-gas wells from producing high consistency water/ crude emulsions after acidizing operations in the wells or decreases the amount and stability of produced emulsions.It is also shown to be an eff...
快速渗透剂 T 是一种国内生产的阴离子型表面活性剂,主要成份是磺酸基丁二酸二辛酯钠盐,易溶于强酸、油和地层水。它代替 OP、ABS、AS 等加入酸化工作液中,可防止或减轻酸化后的油井产出不易处理的高稠度重泥质乳化原油。它的破乳能力强,加入油井环形空间或含水原油罐均可。它还具有驱油能力。本文详细介绍了防乳化、破乳室内和矿场试验结果,简要介绍了活性水驱室内和矿场试验(矿场试验因故中途停止),讨论了此种化学剂的用法和用量。
Response of the lesser grain boret to various foods,pheromone(DL-1 & DL-2)doses, and the combination between lures and pheromone were tested in a biodssay apparatus and probe trap. The most attractive foods were wheat gram nut and cold pressed un -refined oil of soybean. Other un-refined oils of oat; peanut,safflower,pumpkin seed,wheat germ,corn,rice,and mustard were also attractive. The vanillin extracts can cause the aggregation behavior. The two components of pheromone were attraitive, ...
