“…Based on Figure 1, the stability of emulsion was at lowest which at 9.6% when DOPC acted as the only surfactant for sample 3. This finding agreed with paper published by Kim et al, where the researcher reported that DOPC is typically unstable because of its molecular structure whose HLB value is moderate (7), therefore resulting in the poor stability of W/O emulsion [6].…”

“…Despite the appealing features of emulsion, this technique used in absorption is not widespread used due to the instability of emulsion [8]. Thus, this study suggesting forming an adhesive emulsion that could stabilize the emulsion based on experiment conducted by some researchers [6]. A stable adhesive emulsion using DOPC as surfactant and the cosurfactant the molecular structure complementary to DOPC was Span 80 and DHA.…”

“…In this study, adhesive emulsion was introduced in the separation process where the particles of the adhesive components are equal in size with emulsion components (the liquid vehicle for carrier throughout which the adhesive components are dispersed). This feature will give the adhesive a continuous surface and creates stronger initial and ultimate adhesion (as there is a larger surface area over which the adhesive bond can form) [6]. Adhesive emulsion was considered in this study to evaluate the separation process of CO2 from gas mixture.…”

Carbon dioxide is one of the main concern in the environment when it comes to energy usage of fuel, even the fuel is coming from natural gas sources. Apart from endangered the environment, carbon dioxide also affects the caloric value of the natural gas itself. The presence of carbon dioxide as contaminants is a nuisance for oil and gas industry as its capability of forming corrosion in pipeline, thus its removal is vital for this industry. The absorption of carbon dioxide in emulsions would be an effective method to prevent corrosion. This study focused on the effects of cosurfactant, complementing 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) with surfactant which is sorbitan oleate (SPAN 80), on the stability of water-in-oil (W/O) emulsion. This study also investigates the use of blended amines which are methyldiethanolamine (MDEA)/2-amino-2-methyl-1-propanol (AMP) and MDEA as aqueous phase. A modified rotating disk contactor (RDC) was used in absorption process and gas chromatography (GC) was used to determine the amount of the CO2 absorbed. Analysis of carbon dioxide absorption through emulsion indicates that different cosurfactant may change the absorption mechanism.

“…13 Thus, it is feasible to utilize functional surfactants to modify rheology of inverted emulsion responsively. 25 Owing to special doubleamphiphilic molecular structure, gemini surfactants possess amazingly high surface activity, which greatly facilitates adsorption and interfacial modication. 26 A number of gemini surfactants have been developed and utilized for emulsion polymerization, 27 gelatinization, 28,29 solubilization, 30 delivery and oil displacement.…”
