SEPARATION DEVICE Russian patent published in 2022 - IPC B01D17/28 B01D21/02 

FIELD: oil and gas industry.

SUBSTANCE: invention is intended for phase separation of three-phase liquid. Device (100) for separating a liquid comprising an oil phase, a solid phase and an aqueous phase includes housing (50); at least one pair of longitudinal partitions (40), which are located along the longitudinal direction of the housing; flow channel (20) formed between each pair of longitudinal partitions and used to provide a fluid flow; and assembly chambers formed between adjacent pairs of longitudinal partitions and/or formed between the longitudinal partition and the inner wall of the housing. Each of the assembly chambers is equipped with at least one transverse partition (30), which is made with possibility to divide the assembly chamber into a cell for collecting the oil phase and a cell for collecting the phase of solid substances in the longitudinal direction. Each flow channel is equipped with several side partitions (10), which are located inclined relative to longitudinal partitions in order to divide the flow channel into several subchannels (25) located substantially in the vertical direction. In the area of each longitudinal partition, where the cell for collecting the oil phase is located, this longitudinal partition is equipped with a guide hole of the oil phase, which is connected to the cell for collecting the oil phase, and in the area of each longitudinal partition, where the cell for collecting the phase of solid substances is located, this longitudinal partition is equipped with a guide hole for the phase of solid substances, which is interconnected with the cell for collecting the phase of solid substances.

EFFECT: providing high separation efficiency.
