The invention also discloses an electric field enhanced medium coalescence demulsification effect evaluation method using the evaluation system, and the evaluation system andmethod have the advantages of rapid evaluation and accurate result, can be used for evaluating the electric field enhanced medium demulsification effect of the O / W emulsion, and realize the optimal design of electric field parameters and medium parameters.

Description

technical field [0001] The invention belongs to the field of oil-water separation in petrochemical industry, and in particular relates to a system and method for evaluating the coalescence and demulsification effect of a continuously flowing electric field enhanced medium. Background technique [0002] In the petrochemical industry, sewage has a wide range of sources, high petroleum content, and serious emulsification. There is a wide demand for demulsification and deoiling of O / W emulsions. For example, in oil fields, oily produced water will be produced after rough separation of downhole produced fluids. . In the prior art, the chemical method of adding demulsifier is generally used for demulsification and separation with traditional equipment such as inclined plate, swirl, air flotation, etc., which has high chemical consumption, large area occupation, poor recovery of waste oil, and secondary pollution of sludge And other problems, and with the change of water quality, ...

AI Technical Summary

Problems solved by technology

In the prior art, the chemical method of adding demulsifier is generally used for demulsification and separation with traditional equipment such as inclined plate, swirl, air flotation, etc., which has high chemical consumption, large area occupation, poor recovery of waste oil, and secondary pollution of sludge And other problems, and with the change of water quality, the agent is replaced frequently, and the universality is poor

In this context, the development of electric field demulsification and oil removal technology is of great significance. However, in the prior art, only a single electric field is used to demulsify and separate the emulsion, and the separation effect is not good.
