Abstract: This invention is directed to a method for defoaming crude oil by the addition of copolymers based on silicone free alkyl acrylics defoamers for crude oils with densities between 10 and 40° API. The alkyl acrylic copolymers at conditions similar to those of gas-liquid separators are efficient foam formation inhibitors in heavy and super-heavy crude oils to reduce foam levels between 15 and 50% faster than non-dosed crude oil. Some acrylic copolymers exhibited a greater efficiency as defoamers than commercial silicones, which promote the defoaming only 20 or 25 vol % faster than the natural foam collapse. Silicones as defoamers present serious problems as the formation of deposits and the deactivation of catalysts in the refining processes. These problems have originated a series of interdictions to use silicon based defoamers and new chemical compounds completely silicon free are required to control the foam levels in the gas/petroleum separation tanks.

Abstract: A low gloss ASA-based resin composition having excellent weatherability and heat resistance is provided. The low gloss ASA-based resin composition is obtained by blending a general SAN copolymer, a heat-resistant SAN copolymer, a crosslinked aromatic vinyl compound-cyanide vinyl compound copolymer, and an amorphous inorganic material with large diameter and extra-large diameter ASA graft copolymers at a predetermined composition ratio. The low gloss ASA-based resin composition is useful in the manufacture of a high-quality molded article in which gloss characteristics are uniformly exhibited because impact resistance, heat resistance, flowability, weatherability, and low gloss characteristics are all excellent, and particularly, the gloss deviation on the entire surface of the injection molded article is significantly reduced.

Abstract: The present invention relates to the application based on alkyl acrylate homopolymers, such as antifoaming agents in crude oils with densities of 10 to 40° API. Evaluation tests in “live” crude oil, under similar gas-liquid separation equipment conditions, showed that these polymers based on alkyl acrylate are effective foaming inhibitors in heavy and super-heavy crude oils, reducing the foam between 15 and 50% faster compared to crude oil without an antifoaming agent. Some acrylics show better performance than commercial silicon-based polymers, which suppress foam 20-25% faster than the blank. The antifoaming agents of this invention, based on alkyl acrylate and totally free of silicon, is an advantageous option, to replace the silicone-based foam inhibitors currently on the market.
