摘要： The present provides a helium gas separation and recovery process involving cryogenic fractionation process, which comprises cooling a dehydrated high-pressure gas stream while maintain velocity and pressure of the stream; reducing pressure of the dehydrated high-pressure gas stream via a Joule-Thompson's process to obtain a partially liquefied gas stream; and iii) subjecting the partially liquefied gas stream to at least one gas-liquid separation process to obtain at least one liquid stream and a gaseous stream comprising helium, and a residual amount of the gaseous components; recycling the liquid stream obtained in step iii) for use as cooling refrigerant to cool the dehydrated high-pressure gas stream; and purifying the unrefined helium gas stream using pressure swing adsorption (PSA) and/or membrane separation process to obtain a helium product stream having a purity of 98.0 mole % or more.

摘要： Processes and apparatuses for providing a high purity hydrogen stream by removing hydrocarbons with a thermal swing adsorption process. An adsorbent is used to remove the hydrocarbons and provide a product stream that is an enriched hydrogen stream. A portion of the product stream is heated and used as a purge stream to desorb the hydrocarbons from the adsorbent. A contaminated stream including hydrogen and the hydrocarbons is cooled and separated in a gaseous stream and a liquid steam. The vapor stream is mixed with the feed stream. A blower may be used with the vapor stream.

摘要： A method for extending useful life of a sorbent for purifying a gas by sorption of an impurity is provided. The method generating a electrical discharge within the gas to obtain a spectral emission representative of a concentration of the impurity. The method also includes monitoring the concentration of the impurity according to the spectral emission. The method also includes lowering the concentration of the impurity by conversion of at least a portion of the impurity into a secondary impurity having a greater affinity to the sorbent than the impurity. The method also includes comparing the concentration of the impurity to a polluting concentration and managing the sorption of the gas onto the sorbent according to the comparison.
