The present invention is an active microchannel fluid processing unit and method of making, both relying on having (a) at least one inner thin sheet; (b) at least one outer thin sheet; (c) defining at least one first sub-assembly for performing at least one first unit operation by stacking a first of the at least one inner thin sheet in alternating contact with a first of the at least one outer thin sheet into a first stack and placing an end block on the at least one inner thin sheet, the at least one first sub-assembly having at least a first inlet and a first outlet; and (d) defining at least one second sub-assembly for performing at least one second unit operation either as a second flow path within the first stack or by stacking a second of the at least one inner thin sheet in alternating contact with second of the at least one outer thin sheet as a second stack, the at least one second sub-assembly having at least a second inlet and a second outlet.

1. A method of making an active microchannel fluid processing unit, comprising bonding together at least one first sub-assembly and at least one second sub-assembly:wherein the at least one first sub-assembly has at least a first inlet and a first outlet; wherein the at least one first sub-assembly comprises at least one first inner sheet stacked in alternating contact with at least one first outer sheet, said at least first one inner sheet having a first major surface in contact with said at least one first outer sheet and a second major surface in contact with an outer sheet or an end block wherein said first major surface and said second major surface are separated by a thickness, and said at least first one inner sheet having at least one solid margin, said at least one solid margin defining at least one edge of at least one slot through said thickness; wherein at least one inner sheet is stacked adjacent at least one outer sheet, wherein said at least one outer sheet has at least one opening positioned within said solid margin, wherein said solid margin sealably spaces said at least one outer sheet, wherein said at least one outer sheet defines at least one longitudinal wall of a flow channel having a length parallel to a sheet length, wherein said first assembly comprises a first flow path, such that, during operation of the bonded unit, a fluid can enter through said at least one opening into at least one slot to flow in a direction parallel to the length of said flow channel and exit through another opening that is located on either said at least one outer sheet having said at least one opening or on a second outer thin sheet disposed on an opposite side of said inner sheet; wherein said at least one outer sheet and said at least one inner sheet form a first stack; and wherein said at least one second sub-assembly comprises at least a second inlet, a second outlet and a second flow path; wherein said second flow path is separate from said first flow path; wherein said second flow path is within said first stack or is in a second stack; wherein said second stack, if present, comprises at least one second inner sheet placed in alternating contact with a second at least one outer sheet; wherein, in the bonded unit, said at least one first sub-assembly is capable of performing at least a first unit operation and said at least one second sub-assembly is capable of performing at least a second unit operation.
