ABSTRACT:
A system and apparatus for regasifying liquefied natural gas (LNG) and other cryogenic liquids on a continuous basis utilizing improved atmospheric air vaporizer heat exchangers of the vertical single pass and parallel connected type. A multiplicity of such heat exchangers is positioned on a defined grid, such as to improve the natural convection of the ambient air heat source. An improved heat exchange system includes heat exchange elements within the heat exchangers comprised of hybrid externally finned elements, smooth interior stainless steel tubes thermally bonded within the externally finned elements, the tubes containing vortex generators. Flow distributors in the form of venturi shaped injectors are positioned at the inlet of each tube of the multiplicity of heat exchangers of the system.
