CONTINUOUS-ACTION CONSTANT VOLUME DEGASSER Russian patent published in 2020 - IPC B01D19/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry, namely to degassing equipment, and can be used for extraction of dissolved gas from drilling fluid by continuous extraction of part of flushing liquid at constant temperature mode from flow at outlet from oil well with its further mixing until formation of gas-air mixture, intended for further transportation and component-by-component analysis. Degasser of constant volume includes peristaltic pump, degassing chamber, at that, degasser comprises sampling device made in form of cylinder perforated in lower part, in the center of which there is a rotor containing blades arranged along it along a spiral connected to a peristaltic pump, the output of which is connected to a mixer containing a mixing chamber with a mixing aperture, a spray splitter and a degassing chamber.

EFFECT: high accuracy and stability of determining content of gas in gas-air mixture extracted from flushing liquid, by creating continuous flow of gas-air mixture at outlet of degasser.
