CA 2741289

Helium is recovered from gas streams containing high concentrations of hydrogen gas and low concentrations of helium gas, such as from the recycle stream from the production of ammonia. The inventive process provides for an integrated process for the recovery of both an enriched helium gas stream product and a high purity hydrogen gas stream product.

Selon l'invention, lhélium est récupéré de flux gazeux qui contiennent des concentrations élevées dhydrogène gazeux et de faibles concentrations dhélium gazeux, comme à partir du flux de recyclage de la production dammoniac. Le procédé de linvention se rapporte à un procédé intégré pour la récupération à la fois dun produit dhélium gazeux enrichi et dun produit dhydrogène gazeux de pureté élevée.
