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

FIELD: pipe line transport; transportation of compressed gas via pipe lines at extensive sections where intermediate compressor station may be constructed. SUBSTANCE: proposed method includes building-up of additional pressure head of gas in main gas line by extraction of gas at intermediate and terminal compressor stations from main gas line followed by additional compression and delivery of ejecting flows of gas to intermediate points of main gas line; device for transportation has linear section of main gas line adjoining terminal or intermediate compressor stations which is provided with at least one additional gas line which is so positioned that gas flows at higher pressure may be supplied to intermediate points of linear section of main gas line in reverse direction. EFFECT: reduced specific usage of metal for manufacture and erection of gas line; reduction of high-pressure units; enhanced reliability and safety of gas line. 3 cl, 2 dwg
