<p>A method for discharging gas-filled containers to a gas pressure that is lower than a first pressure (P1), whereby the gas in the containers is discharged to a process station (A) or environment in which the first pressure (P1) is maintained. Gas from a first container (1) is made to flow through an ejector (9) to a process station (A), and a second container (2), charged with a gas to a second pressure (P2) is connected via the low-pressure inlet on the injector (9) to the flow of gas through the ejector, whereupon the flow of gas from the first container (1) draws gas from the second container (2). A means for carrying out the method comprising a first gas container (1) charged with a pressure substantially higher than P1 which is connected to an ejector (9) via a line (8) fitted with a valve (7), the gas from the first container (1) being discharged via the ejector to the process station (A) and at least one other container (2), charged with gas at a pressure approximately equal to or less than the first pressure (P1) connected to the gas flow from the first container (1) via a line (1) via a line (14) fitted with a line (17).</p> |
