Tatneft has patented a device for treating wastewater containing emulsified oil or its refined products. The development is intended for the oil production and refining industries.
The device is made in the form of a horizontal cylindrical body. Inside it are systems for distributed water input, purified water extraction, accumulated petroleum product extraction, and oil-wetted mechanical impurities extraction. The water input system is two-level: the upper level is in the gas phase, the lower one is in the treated water at a height of one third from the base of the body.
The body is connected to a liquid ring pump through a piping system with a filter and pressure gauges. The water extraction, gas supply, water input, and petroleum product extraction nozzles are perforated with a given diameter, pitch, and angle of inclination of the holes. They are located in the same plane one above the other from bottom to top. All pipelines form a closed sealed system.
The technical result is an increase in efficiency in the preparation of complex raw materials (viscous sulfur-containing oils) due to simplified design, reduced metal consumption, simplified operation, and reduced electricity consumption.
