AN IMPROVED SINGLE COLUMN PRESSURE SWING ADSORPTION (PSA) PROCESS FOR THE SEPARATION OF HELIUM

摘要

The present invention relates to an improved single column pressure swing adsorption (PSA) process for the separation of helium. This invention particularly relates to the use of single column with an improved PSA cycle and a gas storage (surge) vessel to store the product, which is used subsequently for the regeneration / purging of the PSA column.
