Patent ID: 8636040

Claim:
An installation for packaging a gaseous nitric oxide/nitrogen (NO/N 2 ) mixture into at least one container comprising: a source ( 1 ) of gaseous nitrogen (NO), a source ( 2 ) of gaseous nitrogen (N 2 ), at least one filling system ( 3 ) comprising one or more filling stations ( 24 ) configured to be capable of filling gas containers ( 25 ), a first gas line ( 11 ) fluidically connecting the source ( 1 ) of gaseous NO to the filling system ( 3 ), and a second gas line ( 12 ) fluidically connecting the source ( 2 ) of gaseous nitrogen to the filling system ( 3 ), wherein the source ( 1 ) of gaseous NO contains a gaseous premix of NO and nitrogen, and the first gas line ( 11 ) and the second gas line ( 12 ) each comprise a mass flow meter ( 4 , 5 ), each mass flow meter ( 4 , 5 ) being connected ( 14 , 15 ) to a control device ( 6 ) collaborating with each mass flow meter ( 4 , 5 ), wherein the first gas line ( 11 ) and the second gas line ( 12 ) are fluidically connected to the filling system ( 3 ) by a common line section ( 13 ), wherein the control device ( 6 ) acts on a regulating valve ( 31 ) adapted to control a flow of gas heading for the system or systems ( 3 ) from common line section ( 13 ) and adapted for stopping a flow when at least one mass set point has been reached, wherein the control device ( 6 ) also acts on a bypass valve ( 30 ) configured to increase the flow of gas heading towards the system or systems ( 3 ) from common line section ( 13 ) relative to the regulating valve ( 31 ), and wherein the control device ( 6 ) is a computer specifically programmed to act in real time on the regulating valve ( 31 ) and the bypass valve ( 30 ) to cause one to be open while the other is closed.
