Abstract: A heater assembly for a fluid reservoir includes an outer housing coupled to a flange on the fluid reservoir, an inner tubular member disposed within the outer housing, the inner tubular member having a central passageway therethrough, wherein an annulus is formed between the outer housing and the inner tubular member, and a heating device coupled to a lower end of the outer housing and having heating elements which extend upwardly into the central passageway of the inner tubular member.

Abstract: A steam generation assembly is provided for producing steam with foul or unclean fluids for use in operations. The heat is transferred to the foul fluid from a clean steam flowing through a tube bundle and is circulated through a closed loop steam generation system. The tube bundle extends within an outer shell that collects the foul fluid for heat transfer. Outer shell includes a larger volume below the tube bundle than convention heat exchangers so that any particulates and emulsions can gather below the tube bundle rather than attaching or forming on its surface.
