Method to optimize high-pressure, multicomponent gas mixing.

By use of the equations derived herein, a method is outlined to determine the optimum filing sequence and to obtain the maximum possible pressure when two or more pure high-pressure gases are to be transferred to a receiver cylinder in order to prepare a multicomponent gas mixture. The method is valid for any number of gas components, originating from high-pressure storage cyclinders of arbitrary size and pressure and for a receiver cylinder to contain initially one or more of the component gases. Percentage concentrations within 1% of desired are easily obtained with this method.
