Title:
SELF-ADAPTIVE VARIABLE-FLOW CRUDE OIL DEGASSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/024916
Kind Code:
A1
Abstract:
The present invention relates to a self-adaptive variable-flow crude oil degassing method and device. The self-adaptive variable-flow crude oil degassing device comprises a casing, a main flow separation tube, and branch flow separation tubes distributed around the main flow separation, with the branch flow separation tubes being in communication with the main flow separation tube through branch flow tubes. The present invention, by virtue of the special combination of the main flow separation tube and the branch flow separation tubes, is capable of being self-adapted to the fluctuation of the flow rate of the inlet crude oil. When the flow rate varies, because of the special structures of a spin generator and an inverted cone in a main flow separator, and of the branch flow tubes, the branch flow separation tubes are always in an allowable working condition. High-efficiency degassing of crude oil entering the branch flow separation tubes can be guaranteed, a quick and high-efficiency degassing function and an automatic liquid level adjustment function are achieved, and the pressure of downstream equipment is reduced. The self-adaptive variable-flow crude oil degassing device has a simple structure and is convenient to install, and can effectively reduce the floorspace occupied by same and make up for the defects in the prior art.
