PRESSURE INCREASING COMPRESSOR STATION OF GAS CONDUIT Russian patent published in 2006 - IPC F17D1/65 F04D25/00 

FIELD: gas industry branch, possibly compressor station for increasing pressure of natural gas at transporting it.

SUBSTANCE: compressor station of gas conduit is mounted in underground gas reservoir or in gas deposit or just near such objects. Compressor station includes systems for removing from technological gas mechanical impurities, for drying gas. Said station also includes gas pumping aggregates joined at inlet through technological pipelines with system for preparation at least of technological gas, joined at outlet with aggregate for cooling technological gas and joined through shut-off fitting, supply and discharge pipelines with main gas conduit. Unit for cooling technological gas is provided at least with one apparatus for cooling technological gas having at least two heat exchange sections. Each heat exchange section has multi-row bundle of ribbed tubes. Said tubes form in zone of each row (in projection on arbitrary plane normal to vector of flow of outer heat exchange fluid - cooling air fed to tubes and passing through central lengthwise axes of tubes of each row) zones of complete aerodynamic non-transmission corresponding to tube projections onto said plane without taking into account tube ribs; zones of complete aerodynamic transmission corresponding to projections of gaps between turned one to other edges of ribs of tubes adjacent in row, onto said plane; zones of partial aerodynamic transmission restricted at one side by means of arbitrary straight line passing along ribs apexes and restricted at other side by contour of tube body passing along roots of ribs. Specific relation per unit of surface area of said plane of summed areas of projections of zones with different aerodynamic transmission in each row consists respectively (0.85 - 1.15) : (1.82 - 2.17): (1.80 - 2.19).

EFFECT: enhanced efficiency of compressor station, lowered labor and material consumption, improved heat exchange and operational reliability due to optimized parameters of bundle of heat exchanging ribbed tubes.
