Extruded body devices and methods for fluid processing

A method of making a device for processing fluids, the method comprising:

• providing an extruded body having extended cells therein;
• interconnecting at least some of said cells so as to form a first fluidic passage through said body defined principally within said at least some of said cells, the fluidic passage having a longitudinally serpentine path back and forth along the at least some of said cells.

A method of processing a fluid, the method comprising:

• providing an extruded body having multiple elongated cells therein, the body having a fluidic passage therethrough defined principally within a first plurality of said cells, the fluidic passage having a longitudinally serpentine path back and forth along the first plurality of said cells, at least a portion of the fluidic passage, with respect to a plane perpendicular to the cells, lying in path bordered by a second plurality of cells not of the first plurality;
• and
• flowing a fluid to be processed in the fluidic passage while flowing another fluid in one or more of the second plurality of cells.
