The aim of this paper was to investigate the influence of cationic surfactants of different types (hydrocarbon, fluorinat-ed, and silicone surfactants) on the adsorption of carboxy-methylcellulose on the alumina surface as well as stability and electrokinetic properties of such systems using different methods (UV-Vis, DLS, potentiometric However, recent experiments have indicated that although nonionic surfactants can form a mobile micellar pseudophase, leading to the facilitated transport of solubilized hydrocarbon, they can also be adsorbed by the solid matrix and thereby lead to hydrocarbon partitioning into immobile adsorbed surfactants and the sorbed surfactant Synergistic influence of nanoparticles and surfactants have been exploited for achieving effective reduction of surface tension, brine/oil interfacial tension, and the alteration of the reservoir rocks wettability (Kumar and Mandal, 2018a, 2018b; Pal et al., 2019).

Surfactants and Polymers in Aqueous Solution.

Surfactants are essential chemicals and play a significant role in the upstream petroleum industry. Their interfacial properties and strong emulsification capabilities make them suitable for many operations involving surface and interfaces. Apart from that, surfactants are important chemicals and are widely used for other processes as well. They have an important The current work examines the role of surfactant hydrophile-lipophile balance (HLB) on the ability for surfactant reverse micelles to impart charge to particles dispersed in an apolar medium, a study motivated by a number of applications that seek to maximize particle charge in such systems. Previous investigations have shown that relative acid–base properties of the This paper, therefore, focuses on the reviews of the studies conducted on surfactant adsorption for different surfactant types on different reservoir rocks under different reservoir conditions, and the influence of surfactant concentration, salinity, temperature, and pH on surfactant adsorption.

Sánchez-Martín et al. [16] examined the adsorption capacity of surfactants by different clay minerals, and the influence in this process of the ionic or non-ionic nature of the surfactant and its concentration in the clay mineral–water system.

The influence factors, such as the molecular structure of the surfactant, the synergistic effect of surfactant mixtures and cosolvents, inorganic salt ions, and the molecular makeup of the hydrocarbon phase, are further analyzed in more detail to see how they affect the morphology and interfacial properties of the monolayers. Over recent years, the use and development of surfactants and biopolymers has been increased. The interactions between oppositely charged polymers and surfactants lead to the formation of the polymer-surfactant complexes. In this work we focused on studying if different types of cationic surfactants such as hydrocarbon, fluorinated and silicone ones can interact Petroleum-contaminated soil washing experiments were conducted to investigate a novel method for surfactant selection. Particular attention was paid to the effect of surfactant on petroleum removal for individual clay mineral types.

Here, we use molecular dynamics (MD) simulations to investigate the effect of model surfactant molecules (polynuclear aromatic carboxylic acids) on the agglomeration behaviour of gas hydrate particles and disruption of the This review explores the role of surfactants in enhancing or inhibiting the biodegradation of hydrophobic organic compounds (HOCs) by To investigate the influence of surfactant and nanoparticle solutions on polymer injection and reduce the interfacial tension between the aqueous phase and oil, a surfactant was employed. The use of surfactants is essential in the formation of nanoparticles as they greatly affect dispersion (Morsy, 2014).

In order to inspect how surfactant type and presence of oil influence foam stability, foam decay was monitored by imaging foam columns at different times. These images provide insight about the foam texture when the foam column enters the decay regime. ized by the length of the hydrophobic tail. This tail typically consists of a hydrocarbon chain, the alkyl chain. The alkyl chain length can influence the cationic surfactant molecule s A novel technology in this field is based on HOC extraction by means of a mobile phase that increases their mobility, controlled by the increase in the apparent solubility of the compound in water. An increase in the efficiency of this process has been achieved with in situ surfactant-enhanced soil flushing technology [3], [4].

Abstract The aim of this study was to investigate the influence of different types of surfactants on the adsorption, stability, and electro-kinetic properties of the carboxymethylcellulose/alumina system as well as the interactions between the surfactants and the polymer. The authors decided to use fluorinated and silicone surfactants besides the conventional hydrocarbon ones. The The molecular structure of surfactant consists of two parts, one is head which is polar in nature (hydrophilic part), and the second one is a hydrocarbon tail which is generally non-polar in nature (hydrophobic part) as shown in Fig. 1.1. Section snippets Theoretical considerations One mechanism involved in surfactant-enhanced NAPL removal is the enhanced solubilization of NAPL into surfactant solution. The solubilization of a hydrocarbon such as hexadecane in surfactant solution involves partitioning of hydrocarbons into the interior of surfactant micelles.

The present study focused on the thermal stability of the foams stabilized by NPs and the mixtures of the zwitterionic hydrocarbon surfactants (CAD-40) and short-chain fluorocarbon surfactants (FS-50), the core-component of the new environmentally friendly firefighting foams. The molecular interaction between NPs and surfactants is

The increased recovery by surfactants can be partially explained by the reduction in interfacial tension (IFT) between crude oil and brine (up to 90%) caused by the surfactant solutions. Another important reason governing the hydrocarbon recovery is the ability of the surfactants to prevent asphaltene precipitation.

Accepted Manuscript The influence of clay minerals and surfactants on hydrocarbon removal during the washing of petroleum-contaminated soil Surface-active agents (abbreviated surfactants) are amphiphilic molecules consisting of a lyophobic (hydrophobic when in water) and lyophilic (hydrophilic when in water) portions. They are classified according to the nature of the head group: anionic, cationic, amphoteric (zwitterionic), and nonionic. Speciality surfactants of fluorocarbons and silicones can lower the surface In a recent research, the interfacial tension between four anionic surfactants and PCE were lower than that of other CHs [49], which interpreted the enhancement in PCE removal due to the improvement of its mobility.
