Phase initiale : Au d\u00e9but des ann\u00e9es 1970, l'Union Carbide Corporation aux \u00c9tats-Unis a industrialis\u00e9 pour la premi\u00e8re fois la production d'oxyg\u00e8ne par la technologie PSA. Au milieu des ann\u00e9es 1970, le proc\u00e9d\u00e9 de production d'oxyg\u00e8ne par adsorption sous pression sous vide (VPSA) a \u00e9t\u00e9 propos\u00e9, am\u00e9liorant consid\u00e9rablement l'\u00e9chelle et l'\u00e9conomie des unit\u00e9s de production d'oxyg\u00e8ne, jetant ainsi les bases de la vulgarisation et de l'application \u00e0 grande \u00e9chelle de la technologie VPSA.
Phase de d\u00e9veloppement : En 1989, l'\u00e9quipement d'oxyg\u00e8ne VPSA de Praxair utilisant un tamis mol\u00e9culaire au lithium a \u00e9t\u00e9 mis en service, marquant l'entr\u00e9e dans une nouvelle p\u00e9riode de d\u00e9veloppement. Les recherches en Chine ont commenc\u00e9 dans les ann\u00e9es 1970, mais en raison de contraintes techniques, ce n'est qu'\u00e0 partir des ann\u00e9es 1990 que la premi\u00e8re unit\u00e9 de production d'oxyg\u00e8ne VPSA a \u00e9t\u00e9 appliqu\u00e9e industriellement.
Phase de perc\u00e9e : Le Coll\u00e8ge de g\u00e9nie chimique et mol\u00e9culaire de l'Universit\u00e9 de P\u00e9kin a r\u00e9ussi \u00e0 d\u00e9velopper le tamis mol\u00e9culaire haute efficacit\u00e9 oxyg\u00e8ne-lithium PU-8<\/strong><\/a> en 1996. En 2000, PKU Pioneer de l'Universit\u00e9 de P\u00e9kin a r\u00e9ussi la production en s\u00e9rie du PU-8, dont les performances ont atteint le niveau de pointe au niveau international. En 2001, PKU Pioneer a r\u00e9ussi l'essai pilote de l'unit\u00e9 de production d'oxyg\u00e8ne VPSA utilisant le tamis mol\u00e9culaire haute efficacit\u00e9 au lithium PU-8 et a r\u00e9alis\u00e9 son application industrielle la m\u00eame ann\u00e9e.
Actuellement, plus de 300 unit\u00e9s de production d'oxyg\u00e8ne VPSA aux performances mondiales de pointe de PKU Pioneer ont \u00e9t\u00e9 construites et mises en service, fournissant des solutions d'approvisionnement en oxyg\u00e8ne rentables et efficaces pour plus de 20 secteurs tels que l'acier, la m\u00e9tallurgie non ferreuse, le verre et la fibre de verre, le ciment, le traitement des eaux us\u00e9es, l'incin\u00e9ration des d\u00e9chets, etc. C'est le leader de l'industrie VPSA \u00e0 l'\u00e9chelle mondiale.<\/p>","protected":false},"excerpt":{"rendered":"
