摘要： Disclosed herein is a methanol production process that includes a membrane separation step or steps. Using the process of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. As an additional advantage, the membrane separation step generates a hydrogen-rich stream which can be sent for other uses. An additional benefit is that the process of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.
摘要翻译：本文公开了包括膜分离步骤或步骤的甲醇生产方法。使用本发明的方法，通过降低该方法的压缩要求和/或提高甲醇产物产率来提高合成气生产甲醇的效率。作为另外的优点，膜分离步骤产生可以发送用于其它用途的富氢流。另外的好处是，如果更多的合成气或二氧化碳可用，本发明的方法可以对现有甲醇装置进行脱瓶，从而允许将进口的二氧化碳进料到合成循环中。这是一种隔离二氧化碳的方式。

摘要： Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.

摘要： The process of liquid-liquid extraction of gallium from sodium aluminate liquor used in the Bayer alumina process, uses an organic extractant comprising a diluent and a substituted hydroxyquinoline such that gallium and some aluminum are extracted into the organic phase.In five successive steps, the organic extractant solution loaded with gallium and aluminum is first contacted with an aqueous mineral acid solution, during which the acid solution strips the loaded solution of gallium and aluminum. Next, the phases are separated and a chloride salt or hydrochloric acid is dissolved in the acidic solution of gallium and aluminum which is then contacted with an organic solvent, e.g. n-butyl acetate. Aluminum remains in the aqueous acid solution whereas the organic solvent becomes loaded with gallium.After the phases have been separated, the organic solvent is separated from gallium chloride, which forms the feed for producing pure gallium.

摘要： Disclosed herein are methanol production processes that include a sweep-based membrane separation step using a membrane that is selective to carbon dioxide over hydrogen. Using the processes of the invention, the efficiency of methanol production from syngas is increased by reducing the compression requirements of the process and/or improving the methanol product yield. In certain embodiments, a hydrogen-rich stream is generated; this hydrogen-rich stream can be sent for other uses. An additional benefit is that the processes of the invention may debottleneck existing methanol plants if more syngas or carbon dioxide is available, allowing for feed of imported carbon dioxide into the synthesis loop. This is a way of sequestering carbon dioxide.
