Underground gas storage process

摘要: 961,415. Storing gases under pressure. GULF RESEARCH & DEVELOPMENT CO. Sept. 18, 1961 [Sept. 30, 1960], No. 33300/61. Heading F4P Fuel gas is stored underground in waterbearing porous rock by injection through wells 12 after primary of cheap inert gas, e.g. nitrogen, scrubbed flue or air which may contain oxygen consuming oil and be followed a volume at least as large that fuel would otherwise have been trapped upon withdrawal the gas. To detect contamination 20% mixed prior to with radioactive tracer krypton 85, radioactivity detector chamber 23 incorporated delivery pipe 22, being electrically connected an amplifier counting rate meter 26 which, via relay 27, controls electrical power from terminals 28 motor-controlled throttling valve 24 shut-off restrict delivery.
