Abstract

The invention relates to a method for performing emulsion breaking on an oil-water emulsion by an ultrasonic wave. In the method, one or more ultrasonic generators are arranged in a raw material storage tank or a settlement tank in the gravity settling direction, only one ultrasonic generator acts in the direction of the same vertical line. An emulsion breaking device for implementing the method comprises the raw material storage tank or the settlement tank, and one or more ultrasonic generators are arranged at the bottom or / and top of the raw material storage tank or the settlement tank. The ultrasonic generators are distributed reasonably according to structural size and ultrasonic radiation areas, so that the ultrasonic generators cover comprehensively, and are prevented from being overlapped. The ultrasonic generators are connected with ultrasonic distributors, and one ultrasonic generator is arranged in one ultrasonic distributor. The action direction of the ultrasonic wave is the vertical direction and is consistent with the gravity settling direction, so the driving force is added in the oil-water settling direction, and the oil-water settling speed is accelerated. The device is uniform in ultrasonic wave energy distribution, excellent in emulsion breaking effect, simple in operation, convenient to run and maintain and low in running cost.

Description

technical field

[0001] The invention relates to a method and device for pretreatment of crude oil (or dirty oil) in oil fields and refineries, belongs to the technical field of demulsification of oil-water emulsions, and can be widely used in oil exploitation and refining. Background technique

[0002] In recent years, with the gradual reduction of petroleum resources and the continuous increase of people's demand for petroleum products, oilfield companies have been prompted to adopt various measures to increase oil production. The wide application of tertiary oil recovery technology has used reserves that were difficult to exploit in the past. The exploitation of these crude oil reserves , will inevitably lead to deterioration of crude oil properties. In particular, the extensive application of polymer flooding, multi-component composite flooding, and surface active flooding has resulted in intensified emulsification of heavy and poor-quality crude oil and stable emulsified...
