Abstract: A three-stage degassing and dewatering device includes a first-stage degasser, a second-stage degasser, an oil drainer, a rod electrode, a dewaterer, and a water drainer. The first-stage degasser implements a first-stage axial-flow type collision buffer degassing and dewatering operation, forming a first-stage crude oil after removing some of the gas and water in the gas-containing and water-containing crude oil. The second-stage degasser implements a second-stage elevated efficient degassing operation, forming a second-stage crude oil after removing the remaining gas in the first-stage crude oil. The rod electrode constructs a dynamic electric field with a high frequency and a high voltage, and implements a third-stage high-frequency and high-voltage rapid dewatering operation together with the dewaterer, forming a qualified crude oil after removing the remaining water in the crude oil emulsion.

Abstract: A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.
