FIELD: separation.
SUBSTANCE: present invention relates to a process additive formulation for foam reduction and/or for increasing dehydration in a process comprising an aqueous medium, and can be used in the oil industry, in processing food and beverages, in the mining industry, in the textile industry, in agriculture, in the pulp and paper industry and the like. Formulation comprises 50–80 % of a copolymer of acrylate and / or methacrylate in an organic diluent which is diethylhexyl adipate and 5–50 % of oil obtained from renewable raw materials, or mineral oil. Polymer is prepared by polymerising a monomer mixture prepared in advance, comprising alkyl acrylate monomers and / or alkyl methacrylate monomers and hydroxyalkyl acrylate monomers, and acrylic acid or methacrylic acid. Formulation does not contain silicon oxide, silicone and silicone surfactant.
EFFECT: technical result is providing simultaneous reduction of foaming and improvement of dehydration.
