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.
