Patent ID: 8733384

Claim:
A system for boosting the pressure of pressurized pipeline gases comprising: a host pipeline containing a pressurized pipeline gas; a boost pipe disposed within said host pipeline and forming an annular region between said boost pipe and said host pipeline, said boost pipe containing a supplemental pipeline gas having a higher pressure than said pressurized pipeline gas; a supplemental pipeline gas supply connected with said boost pipe; at least one pressure sensor disposed within said host pipeline adapted to measure a differential pressure between said pressurized pipeline gas and said supplemental pipeline gas; and flow control means for initiating a flow of said supplemental pipeline gas from said boost pipe into said annular region at a first set differential pressure and for shutting off said flow of said supplemental pipeline gas at a second set differential pressure, said flow control means comprising a plurality of flow control valves disposed at periodic distances along said boost pipe and within said host pipeline, each said flow control valve adapted to provide fluid communication between an interior of said boost pipe and said annular region.
