MODE OF TRANSPORTATION OF NATURAL GAS ALONG THE MAIN PIPELINE Russian patent published in 2007 - IPC F17D1/02 

Abstract RU 2294481 C1

FIELD: the invention refers to energy-conservation technologies of pipeline transportation of natural gas.

SUBSTANCE: it may be used for controlling the technological process of the main pipeline with simultaneous selection out of gas of valuable ethane, propane, butane components. The technical result of the invention is reduction of energy inputs for maintaining pressure in the main pipeline, provision of stabilization of pressure in the main pipeline. The mode of transportation of natural gas along the main pipeline includes its feeding into the main pipeline on the first and the following compressor stations and giving out natural gas from the main pipeline through gas reducing stations and divide it on two flows one of them is directed into the pipeline of high pressure, and the other into a consumer pipe-bend. At that the gas of consumer pipe-bend is preliminary cooled and cleared from condensed and hard fraction, and then further cooling is executed till the temperature below the point of condensation of methane and division of cryogenic liquid and directed to the user, and out of received cryogenic liquid methane is separated from liquid ethane-propane-butane fraction which is returned into the pipeline of high pressure and further into the main pipeline, and detailed methane is directed into the pipe-bend. At that the gas in the pipeline of high pressure is preliminary additionally cooled, compremirated and returned into the main pipeline.

EFFECT: reduces power inputs.
