Abstract

A gas detection and fire suppression system is proposed that includes at least one hydrogen gas detector located proximate to a hydrogen salt cavern wellhead, the at least one hydrogen gas detector configured to generate a signal upon detecting a concentration of hydrogen gas above a predetermined threshold. The system also includes at least one automatic self oscillating fire monitor located proximate to the hydrogen salt cavern wellhead, the at least one automatic self oscillating fire monitor configured to activate upon the receive a signal from the at least one hydrogen gas detector. And the system includes an alarm, wherein the alarm is configured to activate upon the receipt of the signal from the at least one hydrogen gas detector.

First claim

1 . A gas detection and fire suppression system, comprising;
at least one hydrogen gas detector located proximate to a hydrogen salt cavern wellhead, the at least one hydrogen gas detector configured to generate a signal upon detecting a concentration of ambient hydrogen gas above a predetermined threshold, at least one automatic self oscillating fire monitor located proximate to the hydrogen salt cavern wellhead, the at least one automatic self oscillating fire monitor configured to activate upon the receive a signal from the at least one hydrogen gas detector, and an alarm, wherein the alarm is configured to activate upon the receipt of the signal from the at least one hydrogen gas detector.

2 . The gas detection and fire suppression system of claim 1 , further comprising fixed firefighting equipment at the perimeter of an area containing surface facility equipment associated with the hydrogen salt cavern wellhead.

3 . The gas detection and fire suppression system of claim 2 , wherein the surface facility equipment is selected from the group consisting of a control building, maintenance/storage building, tanks, piping, valves, transformers, breakers, injection compressor, and hydrogen dryer.

4 . The gas detection and fire suppression system of claim 2 , wherein said fixed firefighting equipment are provided water from a pressurized firewater ring.

5 . The gas detection and fire suppression system of claim 2 , wherein said fixed firefighting equipment are activated automatically upon the receipt of a signal form the at least one hydrogen gas detector.

6 . The gas detection and fire suppression system of claim 2 , wherein said fixed firefighting equipment are activated manually.

7 . The gas detection and fire suppression system of claim 6 , wherein said fixed firefighting equipment are remotely activated.

8 . The gas detection and fire suppression system of claim 1 , wherein the at least one automatic self oscillating fire monitor is activated automatically upon the receipt of the signal form the at least one hydrogen gas detector.

9 . A gas detection and fire suppression method, comprising;
detecting ambient hydrogen gas in an area proximate to a hydrogen salt cavern wellhead, by means of at least one hydrogen gas detector, and signaling at least one automatic self oscillating fire monitor in an area proximate to the hydrogen salt cavern wellhead, by means of a communicating means configured for communicating between the at least one hydrogen gas detector and the at least one automatic self oscillating fire monitor, and activating an alarm by means of a communication means configured for communicating between the at least one hydrogen gas detector and the alarm.

10 . The gas detection and fire suppression method of claim 9 , further comprising activating fixed firefighting equipment at the perimeter of an area containing surface facility equipment associated with the hydrogen salt cavern wellhead automatically upon the receipt of a signal form the at least one hydrogen gas detector

11 . The gas detection and fire suppression method of claim 10 , further comprising providing said fixed firefighting equipment with water from a pressurized firewater ring.
