Abstract:
A microchannel system comprising:a first laminar flow channel having an upstream end and a downstream end and having first and second sides;a primary stream inlet channel, containing a flowing primary stream, connected to said first side of said upstream end of said first laminar flow channel;a first companion stream inlet channel, containing a flowing first companion stream, connected to said second side of said upstream end of said first laminar flow channel;a residual primary stream outlet channel, containing a flowing residual primary stream, connected to said first side of said downstream end of said first laminar flow channel;a first product stream channel, containing a flowing first product stream having an upstream end and a downstream end, said upstream end of said product stream channel connected to said second side of said downstream end of said first laminar flow channel;a second laminar flow channel having an upstream end and a downstream end, and connected at said upstream end to said downstream end of said first product stream channel; anda second companion stream inlet channel, containing a flowing second companion stream, connected to said upstream end of said second laminar flow channel, whereby said first product stream, and said second companion stream flowing into said second laminar flow channel through said second companion stream inlet channel, flow in adjacent laminar streams in said second laminar flow channel.
