METHOD OF TRANSPORTATION OF COMPRESSED GAS Russian patent published in 2002 - IPC

FIELD: transportation of compressed gases via lines. SUBSTANCE: method includes repeated compression of gas in linear section of main line by means of ejecting gas flow by at least one high-pressure gas flow delivered to main pipe line through one additional gas line laid inside and/or outside gas line cavity. It is preferable to supply high-pressure gas flow to main gas line through one or several additional gas lines of equal or different lengths which is located autonomously in gas line; ejection of gas flow of main gas line is effected in succession by means of two and more high-pressure gas flows supplied via additional gas lines located one in other in cavity of main gas line; high-pressure gas flow is formed by means of successive ejection with the aid of two and more gas flows supplied through additional gas lines located in cavity of main gas line; high-pressure gas flows are fed to main gas line via one or several gas lines of equal or different lengths located outside main gas line; high-pressure gas flow is formed by means of stepped ejection of gas flows in additional gas line system located independently beyond main gas line; high- pressure gas flows are formed by means of ejection of gas flows on one or several gas lines located in additional gas lines: ejection of gas flow of main gas line is effected by means of high-pressure gas flows fed via additional gas line in cavity of gas line and outside it. EFFECT: reduced specific expanses for transportation of gas due to increased pitch of layout of compressor stations. 8 cl, 10 dwg
