Abstract (en)
[origin: US2008250924A1] Processes are described comprising: providing a crude gas stream having a temperature not exceeding 40° C., the crude gas stream comprising at least one organic impurity; condensing at least a portion of the at least one organic impurity from the crude gas stream at a temperature not exceeding 0° C. to form a prepurified gas stream; and subjecting (at least a portion, preferably substantially all, and more preferably the entirety, of) the prepurified gas stream to adsorption on a first adsorption medium to provide a purified gas stream; wherein the first adsorption medium is subjected to a regeneration comprising: (i) providing a circulating inert gas stream having a temperature of at least 100° C.; (ii) passing the circulating inert gas stream over the first adsorption medium to form an organic impurity-loaded inert gas stream; (iii) cooling the loaded inert gas stream to a temperature not exceeding 40° C.; (iv) condensing at least a portion of the organic impurity from the cooled, loaded inert gas stream to provide a prepurified circulating inert gas stream; subjecting (at least a portion, preferably substantially all, and more preferably the entirety, of) the prepurified circulating inert gas stream to adsorption on a second adsorption medium to provide a purified circulating inert gas stream; and recycling the purified circulating inert gas stream to the circulating inert gas stream.
