International Classification:

B01D 53/04

US Classification:

95130, 95143, 95148, 95903

Abstract:

The disclosed invention relates to a process for separating methane or nitrogen from a fluid mixture comprising methane and nitrogen, the process comprising: (A) flowing the fluid mixture into a microchannel separator, the microchannel separator comprising a plurality of process microchannels containing a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the methane or nitrogen is sorbed by the sorption medium, and removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing the methane or nitrogen from the sorption medium and removing the desorbed methane or nitrogen from the microchannel separator. The process is suitable for upgrading methane from coal mines, landfills, and other sub-quality sources.

US Classification:

423584, 96 4, 423588, 423591, 423659

Abstract:

The present invention includes methods and apparatuses that utilize microchannel technology and, more specifically in exemplary form, producing hydrogen peroxide using microchannel technology. An exemplary process for producing hydrogen peroxide comprises flowing feed streams into intimate fluid communication with one another within a process microchannel to form a reactant mixture stream comprising a hydrogen source and an oxygen source such as, without limitation, hydrogen gas and oxygen gas. Thereafter, a catalyst is contacted by the reactant mixture and is operative to convert a majority of the reactant mixture to hydrogen peroxide that is withdrawn via an egressing product stream. During the hydrogen peroxide chemical reaction, exothermic energy is generated. This exothermic energy is absorbed by the fluid within the microchannel as well as the microchannel itself. In a preferred embodiment, a heat exchange fluid is in thermal communication with the microchannel housing the exothermic reaction and is operative to absorb a portion of this exothermic energy and transfer such energy from the microchannel.

International Classification:

B01D 53/04
B01J 19/00

US Classification:

95106, 95115, 95130, 95143

Abstract:

The disclosed invention relates to a process and apparatus for separating a first fluid from a fluid mixture comprising the first fluid. The process comprises: (A) flowing the fluid mixture into a microchannel separator in contact with a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the first fluid is sorbed by the sorption medium, removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing first fluid from the sorption medium and removing desorbed first fluid from the microchannel separator. The process and apparatus are suitable for separating nitrogen or methane from a fluid mixture comprising nitrogen and methane. The process and apparatus may be used for rejecting nitrogen in the upgrading of sub-quality methane.

US Classification:

516 18, 516 10, 516928, 516929

Abstract:

The disclosed invention relates to a process for making a multiphase mixture, comprising: flowing a first fluid stream through a process microchannel, the first fluid stream comprising at least one liquid and/or at least one gas, the process microchannel having an apertured section; flowing a second fluid stream through the apertured section into the process microchannel in contact with the first fluid stream to form the multiphase mixture, the second fluid stream comprising at least one gas and/or at least one microbody-forming material, the first fluid stream forming a continuous phase in the multiphase mixture, the second fluid stream forming a discontinuous phase dispersed in the continuous phase.
