Hp gas supply system and method

A method for providing high pressure (HP) gas to a low pressure (LP) gas destination using a primary HP gas supply source and a reserve HP gas supply source, comprising the steps of:

• (1) supplying a primary HP gas stream at a primary high pressure PH from the primary HP gas supply source, and pressure regulating the primary HP gas stream to a supply gas stream at a primary regulated pressure P1;
• (2) supplying a reserve HP gas stream at a reserve high pressure PR from the reserve HP gas supply source, and pressure regulating the reserve HP gas stream to the supply gas stream at a reserve regulated pressure P2 that is less than the primary regulated pressure P1;
• (3) further regulating the supply gas stream to a low pressure (LP) usage stream at a regulated usage pressure P3 that is less than P1 and P2;
• wherein when the primary high pressure Ph falls to the primary regulated pressure P1, the primary HP gas supply source is substantially depleted, and both the primary HP gas stream and the reserve HP gas stream are supplied to the supply gas stream that is regulated to the LP usage stream at the regulated usage pressure P3, and when primary high pressure PH falls to the reserve regulated pressure P2, the primary HP gas supply source is depleted, and only the reserve HP gas stream is supplied to the supply gas stream that is regulated to the LP usage stream at the regulated usage pressure P3;
• (4) providing a one-direction flow means that only allows a flow of gas from the primary HP gas supply source to the reserve HP gas supply source;
• (5) replacing the substantially depleted or depleted HP gas supply source with a replacement primary HP gas supply source, and resupplying a primary HP gas stream at a replacement primary high pressure;
• and
• (6) passing an amount of the primary HP gas stream from the replacement primary HP gas supply source through the one-direction flow means to the reserve HP gas supply source, until the gas pressure of the gas within the replacement primary HP gas supply source and the gas within the reserve HP gas supply source equilibrate.

A method for a gas storage pressure within a reserve high pressure (HP) gas supply source, comprising the steps of:

• (a) providing (1) a primary HP gas supply source with an primary shutoff valve and containing a gas at a primary high pressure PH, (ii) a primary HP manifold connected in fluid communication with a primary HP regulator, (iii) providing a reserve HP gas supply source with an reserve shutoff valve and containing a gas at a reserve high pressure PR and (iv) a reserve HP manifold connected in fluid communication between an outlet of the reserve shutoff valve and a reserve HP regulator, wherein the primary high pressure PH is greater than the reserve high pressure PR;
• (b) providing a one-way flow valve having an inlet in fluid communication with the primary HP manifold, and an outlet in fluid communication with the reserve HP manifold;
• (c) opening the reserve shutoff valve to place the reserve HP gas supply source in fluid communication with the reserve HP manifold;
• (d) connecting an outlet of the primary shutoff valve of the primary HP gas supply source into fluid communication with the primary HP manifold;
• (e) opening the primary shutoff valve the primary HP gas supply source to place the primary HP gas supply source in fluid communication with the primary HP manifold;
• and
• (f) passing an amount of the gas from the primary HP gas supply source through the one-direction flow means, and into the reserve HP gas supply source, until the gas pressure of the gas within the primary HP gas supply source and the gas within the reserve HP gas supply source equilibrate.
