摘要： The present invention relates to an integrated membrane/adsorbent process and system for removal of carbon dioxide from natural gas on a ship that houses natural gas purification equipment. Additional membrane units or adsorbent beds are used to reduce the amount of product gas that is lost in gas streams that are used to regenerate the adsorbent beds. These systems produce a product stream that meets the specifications of less than 50 parts per million carbon dioxide in natural gas for liquefaction.

摘要： 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, heating the regeneration gas with a heater after exiting the dryer, 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 cooling the second adsorber by circulating the regeneration gas bypassing the heater.

摘要： The invention is an adsorptive separation process for producing a para-xylene product from a feed stream comprising para-xylene, at least one other C8 aromatic, and a C9 aromatic. An adsorbent comprising X or Y zeolite and a desorbent comprising para-diethylbenzene (p-DEB) are used in an adsorptive separation zone to produce an extract stream comprising para-xylene, p-DEB, and the C9 aromatic and a raffinate stream comprising the at least one other C8 aromatic, the C9 aromatic, and p-DEB. The extract stream is separated in an extract distillation zone to produce a second desorbent stream comprising the C9 aromatic and p-DEB and the raffinate stream is separated in a raffinate distillation zone to produce a third desorbent stream comprising the C9 aromatic and p-DEB. At least a portion of at least one of the second desorbent stream and the third desorbent stream is further separated in a desorbent distillation zone to produce a stream comprising the C9 aromatic.
