Jul 01, 2019 Non-ionic and cationic surfactants provide attractive performance for clay swelling inhibition due to their ability to interact with the negatively-charged active clay surfaces (Cui and van Duijneveldt, 2010). For the first time in the literature, we investigated the performance of Korean red Ginseng extract, referred to as biosurfactant throughout the paper, as a clay
Oct 28, 2019 Static adsorption tests showed that Kaolinite clay containing samples adsorbed significantly more surfactant compared to the samples without Kaolinite clay and the surfactant adsorption was much lower in the presence of negatively charged nanoparticles.
May 19, 2020 The addition of surfactant has less impact on the rheological properties as compared to KCl. The filtration properties of the base mud were unchanged when surfactants were used. However, the commercial inhibitor, KCl, significantly increased the filtration volume that is associated with the disintegration of the clay.
petroleum and water. These are the surfactants that prevent a filter separator from working because they form a surface film around water drops that keeps two drops of water from joining together. In other words, they prevent coalescing. Clay has a marvelous ability to capture molecules of surfactants. The best type is known as attapulgus

May 03, 2017 As the final processing step, clay filter absorbs oil soluble surfactants and particulate matter present in jet fuel. Currently Attapulgite clay is
Surfactants can inhibit filter operation by affecting the pores or by neutralising the effect of water absorbents (activated alumina, non-woven absorbent fibres/powders, atapulgus clay, bentonite, activated carbon, molecular sieves or natural zeolites). Filtration basics Particulate removal from jet fuels is generally accomplished
Dec 11, 2009 I like the bentonite clay powder blends that can treat a wide variety of cleaning wastewaters. They are quick, simple, and some can break emulsions stabilized by nonionic surfactants as well as remove the low parts per million. If needed you can polish with granular organophilic clay and/or activated charcoal filtration.
Nov 01, 1998 A clay treater removes surfactants from the fuel, preventing the downstream filter separators from being disarmed and unable to remove water. The clay treater contains canisters or bags filled with very fine clay granules, also referred to as fullers earth, that adsorb (collect, adhere to) surfactants on a molecular level.
May 13, 2017 Surfactants are used in drilling fluids as emulsifiers, dispersants, wetting agents, foamers and defoamers, and to decrease the hydration of the clay surface. The type of surfactant behavior depends on the structural groups of the molecules. Various Other Additives. There are a plethora of other additives for drilling fluids.

Jan 01, 2015 Filtration control is an important property of a drilling fluid, particularly when drilling through permeable formations where the hydrostatic pressure exceeds the formation pressure. ... Thus, the clay may be treated with a cationic surfactant to displace the cations that are naturally present at the clay surfaces. The cationic surfactant ...
Clay minerals can be modified organically by a cationic surfactant resulting in materials known as organoclays. The organoclays have been used as adsorbents of most of the organic contaminants in the aqueous solution and oxyanions of the heavy metal. In this study, a Colombian bentonite was modified with hexadecyltrimethylammonium bromide to obtain an
Aug 24, 2020 Moreover, the surfactant showed comparable performance with commonly used clay stabilizer (KCl) and commercially available cationic surfactant dodecyltrimethylammonium bromide (DTAB) used in the industry. It was observed that the synthesized surfactants reduced rheological properties, increased the particle size of bentonite and filtration ...

Jun 29, 2021 Surfactants. Last Updated on Tue, 29 Jun 2021 Horizontal Directional. Surfactants, or soaps, are wetting agents that are used to break clay water bonds and disperse clay particles to stop or break up clumps. Surfactants are usually used in sticky clays.

Jun 18, 2021 In this study, a novel gemini surfactant is used as a clay stabilization additive in the conventional fracturing fluids to inhibit the swelling of clays. For this purpose, compressive strength and tensile strength experiments were carried out on the rock samples treated with conventional clay stabilizing additive and the novel gemini surfactant.
The adsorption of the cationic surfactant, cetyltrimethylammonium chloride (CTMA) from aqueous solutions on attapulgite was studied. Attapulgite is a clay mineral that has many applications, especially in agriculture and industry. It has not been studied extensively compared with other clay minerals for its sorption properties in environmental applications.
of polymers along with surfactants. Polymer-surfactant interactions in flotation are studied here for quartz, which along with clay is present in coal, oil shale etc., using nonionic, anionic, and cationic polymers, and anionic and cationic surfactants. Polymers are found under most conditions to affect notation.
Jul 31, 2018 Surfactants are a primary component of cleaning detergents. The word surfactant means surface active agent. As the name implies, surfactants stir up activity on the surface you are cleaning to help trap dirt and remove it from the surface. Surfactants have a hydrophobic (water-hating) tail and a hydrophilic (water-loving) head.

Membranes hold great potential to be used for the successful treatment of oily waste water, but membrane fouling leads to substantial decreases in performance. Here we study the impact of ionic strength on membrane fouling from an emulsion stabilized by the anionic surfactant sodium dodecyl sulfonate (SDS). For this we use a unique combinatorial approach where droplet
