Problems solved by technology

[0004] In the crude oil stabilization process, when the oil-gas mixture enters the separator, some stable foam will be formed on the oil-gas interface. When the oil and gas are separated, some liquid crude oil will be lost in the gas flow when the foam bursts. In order to overcome these problems, it is necessary to Add defoamer, and the general defoamer is pure silicone oil defoamer, high viscosity, not easy to disperse in crude oil, and the addition of a large amount, the defoaming effect is not ideal

Abstract

The invention provides an oilfield industrial defoamer composition, which is prepared from the following components in parts by mass: 20-30 parts of polymethylsiloxane, 30-50 parts of polyether, and 4-50 parts of thickener 8 parts, 10-15 parts of emulsifier, 2-10 parts of nonionic surfactant, the defoamer composition can efficiently eliminate and suppress foaming, stable performance, less dosage, non-toxic and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of oil field technology, in particular to an oil field industrial defoamer composition and a preparation method thereof. Background technique [0002] Liquid foam is a common and serious problem in industrial production. During the paper pulping process, the slurry will generate a lot of surface active substances in situ, and at the same time, the high mechanical force will cause a large amount of air to be mixed in, so air bubbles are easily generated. When the foaming phenomenon is serious, it will greatly reduce the efficiency of pulp washing, and bring great difficulties to conveying and bleaching, affect the quality of pulp, seriously affect production efficiency, and increase the risk of environmental pollution. [0003] At present, defoamers commonly used in industry are usually divided into three categories: polyether defoamers, organic defoamers and silicone defoamers. Compared with the other two defoamers,...
