Abstract

The invention discloses an ultrasonic wave tank type demulsification device and method. The device is provided with a demulsification tank, wherein the top of the demulsification tank is of an inwards-concave type structure or flat plate type structure, an ultrasonic generator arranged in an anti-explosion cabinet controls an ultrasonic transducer, ultrasonic energy provided by one set of ultrasonic transduction distribution device is re-distributed through an ultrasonic distributor, the ultrasonic generator is arranged in the demulsification tank, a homogeneous liquid is filled in the demulsification tank, an oil-water emulsion enters from the lower part of the tank and flows out from the upper part of the tank after being subjected to the action of ultrasonic waves. The method and device are good in ultrasonic action and contact effect, simple in internal structure and convenient to install, are suitable for demulsifying the oil-water emulsion, and especially suitable for tank type demulsification and dewatering in an oil field or oil refinery.

Description

technical field

[0001] An ultrasonic tank-type demulsification device and method belong to the field of petrochemical technical equipment. 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 production, using crude oil reserves that were difficult to exploit in the past, and widely applying tertiary oil recovery technologies, such as polymer flooding, multi-component compounding, etc. The extensive application of technologies such as flooding, surface active flooding, alkali flooding, carbon dioxide flooding, and thermal recovery of heavy oil has resulted in intensified emulsification of heavy and inferior crude oil and stable emulsified structure. It is difficult to quickly achieve effective emulsification by traditional thermochemical means. The purpose of oil-water separation. [00...
