Passive heat and mass transfer system

A heat and mass transfer system, comprising:

• at least one flow distribution head having a nonlinear outer surface;
• at least one downstream conduit extending downstream from the at least one flow distribution head, wherein the at least one downstream conduit has an outer surface with a width that is narrower than a widest width measurement of the at least one flow distribution head;
• at least one fluid supply system configured to release a liquid film onto the nonlinear outer surface such that the liquid film flows on the nonlinear outer surface of the at least one flow distribution head and onto the at least one downstream conduit;
• at least one heat transfer medium supply system in fluid communication with the at least one downstream conduit such that at least one heat transfer medium is delivered to the at least one downstream conduit while the liquid film flows on the outer surface of the at least one downstream conduit;
• an exhaust manifold in communication with the at least one downstream conduit extending downstream from the at least one flow distribution head;
• and
• wherein the at least one heat transfer medium supply system includes at least one conduit extending into the at least one flow distribution head having the nonlinear outer surface.
