A method and a system for purification of oil, wherein the method comprises the steps of: -adding to a contaminated oil provided in a preparation tank a chemical booster for boosting capturing of impurities and / or a separation of phases in the contaminated oil; -waiting for allowing different phases to be separated; -pumping content out from the preparation tank through a fluid connection; -sensing at least one property of the content in the fluid connection; -controlling a valve provided in the fluid connection to transfer the content to a next step in the purification process or to another destination in dependence of the sensed at least one property.

This invention discloses a hydrocarbon phase deacidification device and method for the petrochemical industry, suitable for the deep purification of acidic hydrocarbon emulsions. The device includes a vertical / horizontal tank, integrating an intercepting wire mesh, a heterogeneous particle demulsification and deacidification unit, a primary / secondary series coalescing and settling unit, and a liquid collection and discharge unit. It is equipped with a multi-functional interface for material inlet / outlet and online backwashing. The heterogeneous particle bed exhibits a gradient distribution in particle size and wettability. The coalescing and settling unit includes a heterogeneous fiber module and a tapered perforated corrugated plate to enhance settling. The method involves separating the acidic hydrocarbon phase through demulsification, coalescence, and settling. The hydrocarbon phase is discharged from the top, and the acid phase is discharged from the bottom, with an integrated gas-water / steam online backwashing and regeneration process. This invention offers high separation accuracy, a compact and flexible structure, real-time monitoring and automated operation, long continuous operation cycles, and a deacidification efficiency exceeding 98%.

The application discloses an electric dehydration system and a high-viscosity crude oil oil-water interface position measuring method, and relates to the technical field of oil-water interface position measurement. The application uses signal processing technology to solve the problem that the oil-water interface measurement of an electric dehydrator in an oil field is easily interfered by an electric field and causes signal jump, and simultaneously realizes electric field energy monitoring, interface instrument electric quantity loading real-time fault diagnosis, expands the interface instrument fault monitoring capability, and for the first time invents an interface position measurement signal processing technology and method with active response and adaptive setting, and further improves the stability and reliability of oil-water interface measurement.
