Abstract:
The pulmonary surfactant system includes specific proteins involved in the regulation of surfactant secretion and recycling, conversion of secreted lamellar bodies to tubular myelin, film adsorption, and stimulation of alveolar macrophages. Hydrophobic proteins are essential for the rapid physiological action of exogenous surfactants currently used in clinical practice.

Abstract:
The chemical-enhanced oil recovery (CEOR) method is applied to change reservoir rock or fluid characteristics by injecting alkaline, surfactant, and polymer or a combination of two or three of the compounds. Surfactant flooding improves oil recovery by reducing the interfacial tension between oil and water. Selecting reservoir surfactants, especially microemulsions, requires careful screening. This study predicted waxy oil system interfacial tension using surfactant mixtures at below- and above-optimum salinity.

The widespread use of detergents has raised concern with regard to the environmental pollution caused by their active substances, which are biorefractory, toxic or persistent. Even though anionic and non-ionic surfactants often used in commercial detergents composition are reasonably degradable under aerobic conditions and not particularly toxic at low concentrations, high concentration of surfactants influenced the activated sludge activity and are harmful for the aquatic environment.

Leak of fuels and lubricants occurring during exploration, distribution, refining and storage operations is the major cause of environmental pollution due to petroderivatives dispersion. The quick use of a series of physicochemical and biological techniques is needed to drastically reduce the magnitude of damage provoked by these pollutants. Among them, soil washing proved to be an effective alternative to the remediation of hydrocarbon-polluted sites, mainly if combined with surfactant utilization.

Pulmonary surfactant is a complex mixture of lipids and proteins that lowers surface tension, increases lung compliance, and prevents the adhesion of respiratory surfaces and pulmonary oedema. Pressure can have an enormous impact on respiratory function, by mechanically compressing tissues, increasing gas tension resulting in increased gas absorption and by increasing dissolved gas tensions during diving, resulting in the formation of bubbles in the blood and tissues. The lungs of diving mammals have a huge range of morphological adaptations to enable them to endure the extremely high pressure

The field of action of surfactants encompasses the formulation of dispersed systems in the chemical and petroleum industry and, particularly, in applications such as enhanced oil recovery (EOR) and chemical dewatering (dewatering). In these applications it is necessary to use hydrophilic surfactants that are not sensitive to salinity and water hardness, minimizing their precipitation and improving their performance in terms of interfacial tension decrease. Some of the most widely used surfactants in the industry are linear alkylbenzenesulfonates (LAS-C15-18) due to their low production costs.

Abstract:
Abstract Surfactant performance is a function of its hydrophobic tail, and hydrophilic head in combination with crude oil composition, brine salinity, rock composition, and reservoir temperature. Specifically, for nonionic surfactants, temperature is a dominant variable due to the nature of the ethylene oxide (EO) groups in the hydrophilic head known as the cloud point temperature. This study aims to highlight the existence of temperature operating window for nonionic surfactants to optimize oil recovery during EOR applications in unconventional reservoirs.

Abstract:
It is well established that alcohol ethoxylate surfactant concentration can have a large impact on the temperature-dependent behavior of Surfactant-Oil-Water (SOW) systems, especially for molecularly-disperse commercial surfactants. Although commonly reported Hydrophilic-Lipophilic Deviation (HDL) modeling approaches generally do not account for this concentration dependency, recent efforts have attempted to capture this behavior in terms of replacing the HLD surfactant parameter with a concentration-dependent function. We have prior reported that such an approach enables successful quantitati

Abstract:
Each year, more than 17,000 gas storage wells in the United States lose from 3�5% of their storage capacity and deliverability. In addition, the gas storage industry spends $80�100 million annually to revitalize existing wells; thus, there is an economic incentive to develop new stimulation methods. Limited laboratory information suggests that using surfactants to alter the wettability of the reservoir rock could increase deliverability of gas storage wells. The objective of this project was to develop new technology to improve deliverability from gas storage wells. Two cost-effective surfacta
