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 present invention discloses a novel method to improve the selectivities of polybenzoxazole (PBO) membranes prepared from aromatic polyimide membranes for gas, vapor, and liquid separations. The PBO membranes that were prepared by thermal treating aromatic polyimide membranes containing between 0.05 and 20 wt-% of a poly(styrene sulfonic acid) polymer. These polymers showed up to 95% improvement in selectivity for CO2/CH4 and H2/CH4 separations compared to PBO membranes prepared from corresponding aromatic polyimide membranes without a poly(styrene sulfonic acid) polymer.

摘要： The present invention discloses a new type of high performance polymer membranes derived from aromatic polyimide membranes and methods for making and using these membranes. The polymer membranes described in the present invention were derived from aromatic polyimide membranes by crosslinking followed by thermal treating. The aromatic polyimide membranes were made from aromatic polyimide polymers comprising both pendent hydroxy functional groups ortho to the heterocyclic imide nitrogen and cross-linkable functional groups in the polymer backbone. The high performance polymer membranes showed significantly improved permeability for gas separations compared to the aromatic polyimide membranes without any treatment. The high performance polymer membranes also showed significantly improved selectivity for gas separations compared to the thermal-treated but non-UV-crosslinked aromatic polyimide membranes. The high performance polymer membranes of the present invention are suitable for liquid, gas, and vapor separations, as well as for catalysis and fuel cell applications.

摘要： A process for desulfurizing a gasoline stream while continuing to maintain the octane rating of the blend stock. A gasoline stream containing sulfur compounds and olefins is introduced into a fractionation zone to produce a low boiling fraction containing mercaptan sulfur compounds and olefins, a mid boiling fraction containing thiophene and olefins, and a high boiling fraction containing sulfur compounds. The low boiling fraction containing mercaptan sulfur compounds is contacted with an aqueous alkaline solution to selectively remove mercaptan sulfur compounds. The mid boiling fraction containing thiophene is extracted to produce a raffinate stream containing olefins and having a reduced sulfur content relative to the mid boiling fraction and a hydrocarbonaceous stream rich in thiophene. The resulting hydrocarbonaceous stream rich in thiophene and the higher boiling fraction containing sulfur compounds is reacted in a hydrodesulfurization reaction zone to produce a hydrocarbonaceous stream having a reduced sulfur concentration.

摘要： The present invention discloses high performance polybenzoxazole membranes prepared from aromatic poly(o-hydroxy amide) membranes by thermal cyclization and a method for using these membranes. The polybenzoxazole membranes were prepared by thermal treating aromatic poly(o-hydroxy amide) membranes in a temperature range of 200° to 550°C under inert atmosphere. The aromatic poly(o-hydroxy amide) membranes used for making the polybenzoxazole membranes were prepared from aromatic poly(o-hydroxy amide) polymers comprising pendent phenolic hydroxyl groups ortho to the amide nitrogen in the polymer backbone. The polybenzoxazole membranes may be subjected to an additional crosslinking step to increase the selectivity of the membranes. These polybenzoxazole membranes showed significantly improved permeability for gas separations compared to the precursor aromatic poly(o-hydroxy amide) membranes and are not only suitable for a variety of liquid, gas, and vapor separations, but also can be used in catalysis and fuel cells.

摘要： The present invention provides a process for treating a natural gas stream comprising sending a natural gas stream to at least one membrane unit to produce a permeate stream containing a higher concentration of carbon dioxide and a retentate stream containing a lower concentration of carbon dioxide. Then the retentate stream is sent to an adsorbent bed to remove carbon dioxide and other impurities to produce a natural gas product stream. The regeneration gas stream is sent through the molecular sieve adsorbent bed to desorb the carbon dioxide. In one process flow scheme, the regeneration stream is combined with the permeate stream from the membrane unit. Then the combined stream is sent to an absorbent column to remove carbon dioxide from the permeate stream to produce a second natural gas product stream. In the alternative flow scheme, a second membrane unit is used to improve efficiency.

摘要： The present invention involves the use of a multi-stage membrane system for gas, vapor, and liquid separations. In this multi-stage membrane system, high selectivity and high permeance or at least high selectivity polybenzoxazole membranes or cross-linked polybenzoxazole membranes are applied for a pre-membrane or both the pre-membrane and the secondary membrane. A primary membrane can be from conventional glassy polymers. This multi-stage membrane system can reduce inter-stage compression cost, increase product recovery and product purity for gas, vapor, and liquid separations. It can also save the cost compared to the system using all the high cost polybenzoxazole membranes or cross-linked polybenzoxazole membranes.
