The organophilic clay was developed by dissolving about 20 g of physically beneficiated clay in 1 L of water at 70–80 °C and homogenized at 250 rpm for 90 min. A calculated amount of CTAB, based on CEC of the clay, was added to 500 ml of water containing about 4 ml of con HCl. The two were mixed together and further homogenized for another ...
What is Organophilic Clay? Organophilic clay, also known as a rheological additive, is a chemically modified bentonite clay used to enhance the viscosity and flow properties of various formulations.. The modification involves adding quaternary ammonium salts and other organic cations to the clay, transforming its surface from hydrophilic (water-attracting) to organophilic …

ORGANOCLAY PM-199: Our second finest grain media, ORGANOCLAY PM-199 features high adsorption capacity of oils, greases, and other NAPL. When used as an in-series filtration media prior to an activated carbon vessel, ORGANOCLAY PM-199 extends the life and adsorbency of the activated carbon by removing larger molecular organics that can cause fouling.
Organophilic clays are clay minerals that have been treated with oil-wetting agents, which will make the clay oil-dispersible. Organophilic clays mixed in OBDF do not exhibit same viscosity or suspension characteristics as in water-based
Conventional organophilic clays, when used as rheological additives in oil based invert muds, display marked viscosity loses in the mud when these muds are heated much above 350° F, whereas muds prepared according to the present invention are dramatically more viscosity stable at temperatures through 500° F. The present invention relates to the discovery of oil based …
To address that problem, a new mineral-oil-based drilling fluid (MOBDF) was created by replacing the conventional organophilic clay with a novel polymer. Introduction. …
These ions reduce the surface energy of the clay, making it more organophilic, thus facilitating access between the layers [6]. The modification process can cause a significant change in the ...
In this study, the impact of VG69 organophilic clay on the rheological properties of gasoil-based drilling muds (invert emulsions) was investigated. The flow curves of gasoil-based drilling muds as a function of the dose of VG69 organophilic clay
Organoclay is also known as Organophilic clay, rheology modifier and organo clay etc.Organophilic clay is regarded as a rheological additive and anti settling agent, used in paints, coatings, inks, and lubricating grease systems.
The focus of this Special Issue will be to gather papers on current knowledge in the areas of the obtainment, characterization, properties, and applications of organophilic clays, covering topics such as organoclay complexes, rheological properties, clay/polymer nanocomposites, sorption of toxic substances, cosmetics, toiletries, and health.
Evonik is a leader in supplying chemistries for the formulation of organophilic clays. Organophilic clays provide rheology or viscosity control for drilling muds and other oil and gas fluids. Whether it is the wet or dry method, offshore or land based, normal or HTHP wells, our ADOGEN® and VARIQUAT® chemistry provides great stability.
Organoclay can be utilized as a fixed-bed media in a column operation. This specialty media offers a high efficient alternative to Granular Activated Carbon (GAC) when applied as a flow …
Organophilic clays, obtained mainly from bentonites and quaternary ammonium salts, stand out among the products obtained. They possess properties such as swelling in …
Organophilic lignite is typically used in drilling operations where the rock formations are relatively soft and contain high amounts of clay. The additive helps to reduce the swelling of clay particles in the drilling fluid, which can lead to …
ORGANOPHILIC CLAY -BASE THICKENERS by J. W.JORDAN Baroid Division, National Lead Company, Houston, Texas ABSTRACT The clay minerals, generally characterized by their small particle size, affinity for water, and response to chemical changes in their environment, are noted for their gelling and viscosity-increasing abilities in aqueous systems.
The S0 pellet ( lauric acid + 0% organophilic clay) shows that the MCP is molten in the form of a liquid state. The S1 pellet (0.15% organophilic clay) showed a leak of composite material. The S2 tablet (0.5% organophilic clay), showed that a large part of the lauric acid integrated into the organophilic clay left a stain on the filter paper.
