摘要： A problem of the crude oil industry is the presence of large amounts of water and salts, which can not be efficiently removed by conventional dehydrating polymers. In addition, the acid stimulation operations of petroleum wells cause the chemical degradation of demulsifiers such as polyethers and phenolic resins, reducing drastically their efficiency as water and salt removers. Disclosed herein is a series of new copolymers that are combinations of an alkyl acrylate and a carboxyalkyl acrylate, synthesized by semi-continuous emulsion polymerization (under starved feed conditions), which ensures both the homogeneity of the different chains as well as the randomness of the monomers distribution. The acrylic-carboxyacrylic copolymers show good performance as water/oil emulsion breaker initiators, water droplet coalescers and clarifiers of the remaining aqueous phase. These novel acrylic-carboxyacrylic copolymers show a higher clarification capacity in comparison with acrylic copolymers [19], vinyl acrylics [12] and polyethers.

摘要： 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.

摘要： 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.

摘要： The present invention is related to the use of ethylene alkanoate-alkyl acrylate bipolymers with a high randomness monomers distribution, which are synthesized by semicontinuous emulsion polymerization process, characterized because it is carried out using slow addition rate of the pre-emulsion feeding ({dot over (q)}≤0.009 kg·L−1·min−1), stabilized this last one by alkyl glycol ether type surfactants, at temperatures higher than 75° C. and with solids contents above 25 wt %, which avoids the formation of large sequences (blocks) of a same monomer. This structural characteristic gives the ethylene alkanoate-alkyl acrylate bipolymers a high efficiency as chemical agents for removal of complex water/crude oil emulsions of crude oil blends.
