“…The alternative is to add a branched surfactant. Abe et al (Abe et al, 1986) found when a linear surfactant was used aloneat room temperature, a large amount of alcohol was needed to have microemulsion free of liquid crystals; but when twin-tailed surfactants were used, less, or even no alcohol was needed, depending on the location of the hydrophilic group. Based on this finding, IOS 1518, which is a twin-tailed surfactant with the sulfonate group distributed along the hydrocarbon chain, was blended with N67-7PO S.…”

Surfactant flooding has the potential to significantly increase recovery over that of conventional waterflooding. The availability of a large number of surfactant structures makes it possible to conduct a systematic study of the relation between surfactant structure and its efficacy for oil recovery. A combination of two surfactants was found to be particularly effective for application in carbonate formations at low temperature. A formulation has been designed for a particular field application.

“…Typical cosurfactants are short chain alcohols, ethanol to butanol, glycols, or medium chain alcohols, amines, or acids (Paul and Moulik, 1997). Abe et al (1986) concluded that the role of the cosurfactant is to destroy liquid crystalline or gel structures that form in place of a microemulsion phase. It was also concluded that cosurfactant free microemulsions in most systems cannot be made except at high temperatures to achieve a microemulsion phase in the 25-40 • C range, cosurfactant must be used.…”

This study attempted to improve the adsorption performance of calcined diatomite for the removal of colour from wastewaters through modification with microemulsions. The surface area, pH ZPC , Fourier transform infrared (FTIR) of calcined diatomite and µE-CD were studied. It is found that an increase in the BET surface area, pH ZPC and total pore volume after modification was obtained. A decrease in average pore volume was observed after modification. This suggests that the pore opening deceased to be in the micro-and meso-pore region hence the adsorption capacity for the modified adsorbent will be enhanced by reducing the escaping of dye molecules. The influence of concentration, pH and particle size on the adsorption capacities of methylene blue (MB), hydrolysed reactive black (RB) and hydrolysed reactive yellow (RY) was investigated. It was concluded from FTIR and pH analysis that the predominant mechanism of RY molecules onto µE-CD is by an electrostatic attraction between the carboxylate anion and the dye. In the case of MB and RB, the adsorption mechanism could be a combination of different mechanisms such as electrostatic attraction, capturing by microemulsion micelles in the pores of the calcined diatomite or the hydrophobic attraction. The adsorption capacities were higher than unmodified calcined diatomite. In the case of adsorption of MB molecules, a high adsorption capacity onto µE-CD was obtained.
