摘要： 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.

摘要： A system for processing nitrogen-containing effluent from an industrial process wherein the effluent is cooled and liquid nitrogen is added directly to the cooled effluent. The direct contact and heat exchange produces gaseous nitrogen and liquid organics which are both used to cool the effluent and are subsequently recovered.

摘要： A process and a system for producing helium from a helium-bearing feed gas that is purified in a cryogenic processing unit to produce cryogenic crude helium containing at least 10% helium. The cryogenic crude helium is directly introduced into a thermal swing helium refinery where it is refined. Refrigeration is supplied to the refinery by the cryogenic crude helium from the cryogenic processing unit.
