A stable oil emulsion rabies vaccine with a low viscosity was composed by a formula previously employed for Newcastle disease vaccine. Cattle developed high and sustained antibody levels, and guinea pigs were found to be solidly immune after a single injection of this vaccine. Antibody responses in cattle to 2 oil emulsion ephemeral fever vaccines were not satisfactory after a single injection,...

Microbial Enhanced Oil Recovery (MEOR) is a potential technology for residual heavy oil recovery. Many heavy oil fields in Oman and elsewhere have difficulty in crude oil recovery because it is expensive due to its high viscosity. Indigenous microbes are capable of improving the fluidity of heavy oil, by changing its high viscosity and producing lighter oil fractions. Many spore-forming bacteri...

Low calorie salad dressings are oil-in-water emulsion products, in which the oil content has been substantially decreased. This decrease, however, is accompanied by reduction in the viscosity hence, an undesirable texture. To overcome this, oil replacers are generally used. In this research, maltodextrin and xanthan gum were used to replace part of the oil in the production of two kinds of sala...

It is well known that the viscosity of fluids could vary by several orders of magnitude with pressure. This fact is not usually taken into account in many important applications involving the flow of fluids through a porous media, like the problems of enhanced oil recovery or carbon dioxide sequestration where very high pressure differentials are involved. Another important technical problem wh...

An experimental investigation of oil retention and pressure drop characteristics for R1234yf, R134a and R410A with POE 100 is presented, for horizontal and vertical suction lines of 10.2 mm internal diameter. Conditions of operation include a saturation temperature of 13 °C and a superheat of 15 °C, with the superficial vapor velocity and the Oil in Circulation Ratio (OCR) both varied in the ra...

gas injection into heavy oil reservoirs could result in high ultimate recovery of oil. experimental studies showed that an application of a combined technology of gas assisted gravity drainage (gagd) and vapor extraction (vapex) could increase final oil recovery of a candidate viscous oil reservoir. in this paper the results of laboratory investigation are presented, including pressure-volume-t...

Abstract—Five palm oil ether monoesters utilized as novel biodiesels were synthesized and structurally identified in the paper. The investigation was made on the effect of ether species on physicochemical properties of the palm oil ether monoesters. The results showed that density, kinematic viscosity, smoke point, and solidifying point increase linearly with their –CH2 group number in certain ...

The bioemulsifier V2-7 is an exopolysaccharide (EPS) synthesized by strain F2-7 of Halomonas eurihalina and it has the property of emulsifying a wide range of hydrocarbons i.e. n-tetradecane, n-hexadecane, n-octane, xylene mineral light and heavy oils, petrol and crude oil. Characteristics of exopolysaccharide V2-7 produced in media supplemented with various hydrocarbons (n-tetradecane, n-hexad...

Hydrolysed polyacrylamide (HPAM) mother liquor is mainly used to extract oil. The HPAM solution is needed to filter the impurity using a bag filter before it is injected into the oil well. Therefore, the pressure drop of HPAM mother liquor must be less than 0.02 MPa in the processing of impurity filtration. The influence factors on pressure drop need to be researched. In this work, the computat...

The steady deformation and breakup of emulsion drops in a uniform electric field are considered experimentally. Due to the low volume fraction of inner drops, the emulsions can be effectively assumed as Newtonian fluids with spatial nonuniformity. The measurements of the electrical properties show that the oil-in-water (o/w) emulsion drop behaves like a conducting drop. On the other hand, the w...
