  • Patent number: 10793783
    Abstract: 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.
