UNDERWATER APPARATUS FOR MIXING GAS AND LIQUID FLOWS Russian patent published in 2022 - IPC B01F23/20 B01F25/314 E21B43/01 

FIELD: mixing.

SUBSTANCE: invention is intended for preparing the supply of reservoir products in multiphase pipeline transport to surface or coastal production facilities in underwater production systems; namely, for mixing gas and liquid flows. Underwater apparatus for mixing gas and liquid flows comprises a main process assembly including a mixing chamber, liquid medium input assemblies with an internal flow path in the form of a nozzle, a supply fitting for the main gas or gas-liquid medium, a supply fitting for a liquid medium, a discharge fitting for the gas-liquid or multiphase medium, a load-bearing frame, external pipeline connection assemblies, pipeline fixtures, and a pipeline system. Input assemblies for the predominantly liquid medium have an internal path made in the form of a narrowing nozzle, and are located at an acute angle α to the axis of the mixing chamber in the direction of movement of the main gas or gas-liquid flow.

EFFECT: reduced loss of pressure in the passage of the main gas or gas-liquid flow and in the liquid supply paths, increase in the stability of process modes and operating reliability of the apparatus, and reduction in the weight and size characteristics of the apparatus.
