METHOD FOR SEPARATION OF A FLOW OF A MULTI-COMPONENT MEDIUM (OPTIONS) Russian patent published in 2022 - IPC F25J3/06 

FIELD: low-temperature treatment.

SUBSTANCE: invention relates to methods for low-temperature treatment of a flow of a multicomponent medium, namely, the separation of natural gas. During separation, the flow of a multicomponent medium (hereinafter referred to as the flow) is accelerated in the confuser section of the nozzle channel, after which it is sent to the critical section, where the flow speed is increased to sonic values, then the flow is fed into the diffuser section, where its speed is increased to supersonic values ​​and condensation of the liquid fraction of hydrocarbon gases and heavier C₅₊ hydrocarbons. Next, the flow is fed to the swirling device, evenly distributed along the channels, tangentially twisted around the axis of the nozzle channel with simultaneous expansion of the gas and the release of the liquid fraction into the near-wall layer of the diffuser section. In an embodiment, under the action of a reactive force, the swirling device is driven into rotation, transferring torque to the electric generator. The liquid fraction of heavy hydrocarbons is fed into the annular cavity, and then into the cavity of the droplet and/or solid particles selection unit, and the separated gas flow is fed into the hollow cone, from where it is taken for further use.

EFFECT: invention allows to significantly increase the efficiency of the process of trapping condensed components at supersonic speeds and provide an additional opportunity to generate electrical energy.
