Title:
PROCESS FOR PURIFYING NATURAL GAS AND REGENERATING ONE OR MORE ADSORBERS
Document Type and Number:
WIPO Patent Application WO/2012/024135
Kind Code:
A3
Abstract:
One exemplary embodiment can be a process for purifying a natural gas by using first and second adsorbers. The process may include passing a feed including the natural gas through the first adsorber to obtain a purified natural gas product, regenerating the second adsorber in a heating stage, and regenerating the second adsorber in a cooling stage. The heating stage may include separating a portion of the feed comprised in a regeneration gas, passing the regeneration gas to a dryer for removing water, then heating the regeneration gas, and passing the regeneration gas to the second adsorber to regenerate the second adsorber. The cooling stage may include expelling at initiation of cooling at least a part of a fluid present in the second adsorber to the dryer to desorb water from a molecular sieve in the dryer, and then cooling the second adsorber.
