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.
Procédé de production par adsorption d'oxygène gazeux à partir d'air comprimé,
dans lequel : a) on produit au moyen d'au moins
une unité d' adsorption, de l'oxygène gazeux ayant une pureté supérieure ou
égale à une valeur de pureté-seuil (VPS) donnée et
selon un débit de production (D p) variable, b) on récupère l'oxygène gazeux
produit en a), c) on mesure la pureté en oxygène
gazeux (P p) produit à l'étape a) et on la compare avec la valeur de pureté-
seuil (VPS) préfixée, et d) on ajuste le débit de
production d'oxygène (D p) en fonction de la comparaison faite à l'étape c) de
manière telle que : i) on réduit le débit (D p) de
production d'oxygène lorsque la pureté (P p) de l'oxygène mesurée à l'étape c)
est telle que : VPS > P p,- ou ii) on augmente le
débit (D p) de production lorsque la pureté (P p) en oxygène déterminée à
l'étape c) est telle que : VPS < P p de manière à obtenir
une pureté en oxygène gazeux (P p) telle que : VPS = P p + X avec X < 0,5%. X
