INHIBITOR DOSING UNIT Russian patent published in 2024 - IPC F17D3/12 

FIELD: pipelines.

SUBSTANCE: invention relates to devices for distribution and dosing of hydrate formation inhibitors introduced into flow of natural gas in flow pipelines. Inhibitor dosing unit includes a container with an inhibitor. Inhibitor is supplied from the reservoir via the main pipeline containing the first ball valve, the electromagnetic valve and the second ball valve, as well as a differential pressure sensor on the electromagnetic valve, a pipeline manual supply of the inhibitor from the reservoir, which contains the third ball valve for manual dosing of the inhibitor. Main and manual lines of inhibitor supply from the reservoir are connected to the common inhibitor dosing pipeline with the fourth ball valve. Common pipeline of inhibitor dosing before the fourth ball valve is connected by means of breathing pipeline to cavity of reservoir with inhibitor, which is located above its maximum level. Pressure is released from the cavity of the reservoir with the inhibitor by the fifth ball valve. Inhibitor dosing unit also has a pipeline line for pumping the inhibitor into the reservoir with the inhibitor, which contains a check valve and a sixth ball valve.

EFFECT: possibility of operation at any pressure in the train at constant low consumption of the inhibitor.
