摘要： The present invention relates to an integrated membrane/absorbent/adsorbent process and system for removal of mercury and sulfur compounds from natural gas on a ship that houses natural gas purification equipment. First mercury and most of the sulfur compounds are removed by an adsorbent bed and then the natural gas stream passes through a membrane unit to produce a partially purified natural gas residue stream to be dried and then liquefied and a carbon dioxide permeate stream that can be used as a fuel gas.

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： The invention includes at least two adsorptive separation zones to separate para-xylene from a feed stream comprising C8 aromatic hydrocarbons and at least one C9 aromatic hydrocarbon component. An adsorbent comprising X or Y zeolite and a heavy desorbent are used in the first adsorptive separation zone to produce an extract stream comprising para-xylene and a raffinate stream comprising para-xylene depleted C8 aromatic hydrocarbons, the C9 aromatic hydrocarbon, and the desorbent. The raffinate stream is separated in a raffinate distillation zone to produce a stream comprising the first desorbent component and the C9 aromatic hydrocarbon which stream is further separated in a second adsorptive distillation zone to produce a stream comprising the desorbent and a C9 aromatic hydrocarbon stream.

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, 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.

摘要： The invention involves a process for maintaining a low level of carbon monoxide in a carbon dioxide product stream and also for keeping the carbon monoxide out of the fully shifted synthesis gas. The overall process is a process for treating both fully shifted and partially shifted or unshifted synthesis gas. The carbon monoxide is separately removed by a carbon monoxide stripping column and returned to the partially shifted or unshifted synthesis gas which can then undergo a shift reaction to convert the carbon monoxide to carbon dioxide.

摘要： Methods and systems are provided for producing a xylene product. The method includes fractionating a feed stream to produce a feed bottoms stream and a feed overhead stream. The feed stream includes aromatic and non-aromatic compounds, and more than 5 weight percent of the non-aromatic compounds have a boiling point above 105 C. The feed bottoms stream is de-ethylated to produce a de-ethylated aromatics stream and a light gases stream, where non-aromatic compounds are converted to light gases in the light gases stream. The de-ethylated aromatics stream is fractionated to produce a heavy aromatics stream and an intermediate aromatics stream, and a desired isomer stream is recovered from the intermediate aromatics stream and an isomerized stream in an isomer recovery process. The isomer recovery process produces an isomer raffinate stream, and the isomer raffinate stream is isomerized to produce the isomerized stream.
