  • Patent number: 9441777
    Abstract: Provided is a process and apparatus for exchanging heat energy between three or more streams in a millichannel apparatus, which millichannel apparatus may comprise a heat exchanger which may be integrated with a millichannel reactor to form an integrated millichannel processing unit. The combining of a plurality of integrated millichannel apparatus to provide the benefits of large-scale operation is enabled. In particular, the millichannel heat exchanger enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc.

  • Patent number: 7000427
    Abstract: 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.

  • Patent number: 6622519
    Abstract: 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.
