LINE COMPRESSOR STATION Russian patent published in 2006 - IPC F17D1/65 F04D25/00 

FIELD: gas industry.

SUBSTANCE: invention can be used in compressor stations designed for increasing pressure of natural gas in transportation. Proposed line compressor station of gas pipeline is installed on section of gas main after head compressor station between head station and other line compressor station or between line compressor stations. Said line compressor station includes gas transfer sets connected at inlet by process pipings with preparation system of at least process gas, and at outlet, with process gas cooling plant and, through shutoff valves, supply and outlet pipelines, with gas main. Cooling plant of process gas is furnished with at least one air gas cooling device consisting of at least two heat exchange sections whose heat exchange section has multirow bank of ribbed single-pass pipes forming, within the limits of each row in projection onto conventional plane normal to vector of flow of heat exchange medium-cooling air fed to pipes and passing through central longitudinal axes of pipes of each row, sections of complete aerodynamic nontransparency corresponding to projections onto said plane of pipes, neglecting their ribbing, sections of complete aerodynamic transparency corresponding to projections on said plane of clearances between edges of ribs pointed to each other in row of adjacent pipes, and section of incomplete aerodynamic transparency limited, each, from one side by conventional straight line passing over tops of ribs, and at other side, by contour of pipe body over rib bases. Specific ratio per unit of rate of said conventional plane of summary areas of projections of said sections with different aerodynamic transparency in each row is respectively (0.85-1.15):(1.82-2.17):(1.80-2.19).

EFFECT: improved efficiency of compressor station, reduced labor input and cost of manufacture at high heat exchanger characteristics and reliability of operation owing to optimization of parameters of bank of ribbed heat exchange pipes.
