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.

This invention relates to a process for cooling or liquefying a fluid product (e.g., natural gas) in a heat exchanger, the process comprising: flowing a fluid refrigerant through a set of refrigerant microchannels in the heat exchanger; and flowing the product through a set of product microchannels in the heat exchanger, the product flowing through the product microchannels exchanging heat with the refrigerant flowing through the refrigerant microchannels, the product exiting the set of product microchannels being cooler than the product entering the set of product microchannels. The process has a wide range of applications, including liquefying natural gas.

This invention relates to a process for cooling a product in a heat exchanger, the process comprising: flowing a refrigerant through a set of first microchannels in the heat exchanger; flowing a refrigerant through a set of second microchannels in the heat exchanger, the refrigerant flowing through the set of second microchannels being at a lower temperature, a lower pressure or both a lower temperature and a lower pressure than the refrigerant flowing through the set of first microchannels; and flowing a product through a set of third microchannels in the heat exchanger, the product exiting the set of third microchannels having a cooler temperature than the product entering the set of third microchannels. This process is suitable for liquefying gaseous products including natural gas.
