Improving Thermal Stability of Starch in Formate Fluids for Drilling High Temperature Shales
Starch is one of the most widely used biopolymers in water based drilling fluids to control fluid loss. The thermal stability of starch in common drilling fluids is low (93 °C). In this study, the thermal stability of starch has been evaluated in sodium/potassium formate and potassium chloride fluids. Samples of mud were prepared by formate salts (sodium and potassium) and potassium chloride wi...
متن کاملSpherical Oil Agglomeration (SOA)/ Colloidal Gas Aphrons (CGA) Flotation
The main aim of this experimental work was to develop a separation process using micro- bubbles less than 100 µm in diameter. Micro-agglomerates were produced using 10kg crude oil/tone feed coal treated compared to 250 kg/tone feed coal treated for conventional spherical oil agglomeration. These micro-agglomerates were separated from the unagglomerated minerals by micro-bubble flotation. Colloi...
متن کاملApplication of colloidal gas aphron suspensions produced from Sapindus mukorossi for arsenic removal from contaminated soil.
Colloidal gas aphron dispersions (CGAs) can be described as a system of microbubbles suspended homogenously in a liquid matrix. This work examines the performance of CGAs in comparison to surfactant solutions for washing low levels of arsenic from an iron rich soil. Sodium Dodecyl Sulfate (SDS) and saponin, a biodegradable surfactant, obtained from Sapindus mukorossi or soapnut fruit were used ...
متن کاملCharacterization of Microbubble-Based Drilling Fluids: Investigating the Role of Surfactants and Polymers
Colloidal Gas Aphrons (CGA), consist of gas bubbles with diameters ranging from 10 to 100 micron, surrounded by a thin aqueous surfactant film. This fluid combines certain surfactants and polymers to create the systems of microbubbles. The function of surfactant in CGAs is to produce the surface tension to contain the aphrons. Also, a biopolymer needs to be considered in the formulation as ...
متن کاملColloidal Gas Aphron Extraction of Bioactive Compounds from Brazilian Pinot Noir Grape Pomace
Residues from the food industry are a problem worldwide. Alternatives have been developed in an attempted to extract compounds from fruit pomace in other to apply those as a natural component in different products. This work has the objective to produce two extracts: (1) ethanolic extract and (2) hot water extract; and characterize the chemical composition of these extracts for future applicati...
