METHOD FOR ADJUSTING THE PURITY OF OXYGEN GENERATED BY AN ADSORPTION UNIT BY CONTROLLING THE FLOW RATE |
摘要 |
<p>The invention relates to a method for producing gaseous oxygen by adsorption from compressed air, comprising: a) using at least one adsorption unit for generating gaseous oxygen having a purity greater than or equal to a predetermined purity threshold value (VPS) and according to a variable production flow rate (Dp); b) recovering the gaseous oxygen produced in a); c) measuring the purity of the gaseous oxygen (Pp) produced in step a) and comparing same with a preset purity threshold value (VPS); and d) adjusting the oxygen production flow rate (Dp) on the basis of the comparison of step c) such that: i) reducing the oxygen production flow rate (Dp) when the oxygen purity (Pp) measured in step c) is such that VPS>Pp; or ii) increasing the production flow rate (Dp) when the oxygen purity determined in step c) is such that VPS<Pp in order to obtain a gaseous oxygen purity (Pp) such that VPS=Pp+X, with X<0.5%, X being the standard deviation.</p> |
