AUTOMATIC ODORISATION SYSTEM OF NATURAL GAS Russian patent published in 2013 - IPC G01F13/00 

FIELD: oil and gas industry.

SUBSTANCE: system includes a working tank and an odorant storage tank, which are connected to each other via a pipeline, a pressurisation system of the odorant storage tank, which includes a pressure reducer and an electromagnetic valve, which are connected to each other via a pipeline, a system of suction of odorant vapours from tanks, which consists of an ejector, an odorant dosing system consisting of a dosing machine; at that, all the systems are connected to each other via pipelines. The odorant dosing system additionally includes at least one electromagnetic valve and a dosing machine, which are connected to each other via pipelines; dosing machines are arranged in the odorant working tank, and the pressurisation system of the odorant storage tank is connected via a pipeline to the system for suction of odorant vapours from tanks through the electromagnetic valve that is installed in front of the reduction gear in the high pressure main line. Each dosing mechanism is made in the form of a metering cylinder, on the side surface of which there are two rows of radial through holes at the specified distance from each other, below and above which there installed are check valves; inside the metering cylinder and coaxially to it there installed is a latch mechanism with possibility of being moved together with check valves.

EFFECT: enlarging functional capabilities and reducing overall dimensions.
