Abstract (en)
[origin: EP1547637A2] Method for preparing gas mixtures (A) of at least two components, i.e. oxygen, nitrogen, helium, carbon dioxide, nitrous oxide and carbon monoxide, in desired proportions. Method for preparing gas mixtures (A) of at least two components, i.e. oxygen, nitrogen, helium, carbon dioxide, nitrous oxide and carbon monoxide, in desired proportions comprises: (a) dynamic premixing, in predetermined proportions, of the components to form a premix at pressure, P1, not over 200 bar, containing an intermediate content (Ti) of second component that is greater than its final content (Tf); (b) increasing the pressure of the premix by adding more first component; and (c) stopping the addition when the mixture reaches a second pressure P2 that is above P1 and greater than 170 bar, and has content of second component Tf. An independent claim is also included for a process for filling gas containers with (A) produced by the new method.
