1. An oil separation assembly for use in a high pressure reciprocating compressor, the compressor comprising a suction chamber, a crankcase chamber, and at least one partition member at least partially separating the suction chamber and the crankcase chamber, the at least one partition member including at least one opening, the oil separation assembly comprising:
at least one demisting structure positioned within the crankcase chamber adjacent the at least one partition member at the at least one opening;
a second demisting structure positioned within the suction chamber adjacent the at least one partition member at the at least one opening; and
at least one securing structure secured in operable relation with the at least one demisting structure so as to secure the at least one demisting structure relative to the opening;
wherein the at least one demisting structure and the second demisting structures are independently selected from the group consisting of wire mesh, steel wool, stainless mesh, steel mesh, serpentine channels and combinations thereof.
