Abstract:

Disclosed is an apparatus for exchanging heat with liquid material and particularly liquid material under superatmospheric pressure. A preferred embodiment of the apparatus comprises a pressure vessel for holding a body of the liquid material, and having an inlet and an outlet for the liquid material. Inside the vessel is an integral tube assembly for conducting heat exchange fluid into, through and out of a body of the liquid material in the vessel. The tube assembly comprises a heat exchange fluid feed header, a heat exchange fluid discharge header, and a plurality of heat transfer tubes from the feed header to the discharge header. In a preferred embodiment of the apparatus, the headers are coaxially aligned with a normally vertical axis, and are vertically spaced apart. The headers are joined to conduits passing through the top and bottom of the vessel. These conduits in combination with the vessel support the tube assembly.
