FIELD: gas pipeline transport. ^ SUBSTANCE: method comprises causing gas to flow through by-passes (1), (2), (3), (4), (5), (6), (7), and (8) and main passage (A) parallel to the direction of the flow in the main passage. The velocity of gas in the by-pass passage at the site of its entrance to the main passage is maintained at a level that exceeds the gas velocity in the main passage, thus providing the gas in the main passage with momentum using the excess energy of the gas in the by-pass to accelerate the gas upstream of the inflowing to the main passage. The device comprises main passage, and at least two by-passes. When gas is transported in main passage (A) in a single direction, at least one by-pass is parallel to the gas flow in main passage and is converging. ^ EFFECT: reduced pressure losses. ^ 11 cl, 2 dwg |
