Abstract
A heat exchanger comprising a shell connected to vertically spaced apart horizontally arranged circular upper and lower tube sheets; a plurality of vertically positioned parallel tubes, with each tube extending through and connected to a hole in each tube sheet; a bottom sleeve-supporting plate positioned above, and spaced apart from, the lower tube sheet; a top sleeve-supporting plate positioned below, and spaced apart from, the upper tube sheet; a plurality of sleeves joined to holes in the top and bottom sleeve-supporting plates; each of said tubes being axially positioned in a sleeve so as to provide an annular space between the tube outer surface and the sleeve inner surface so that liquid can flow into the sleeve bottom end and out the sleeve upper end; an inlet to feed a heat exchange liquid into a space between the bottom sleeve-supporting plate and the lower tube sheet; an outlet to withdraw heat exchange fluid from the shell side of the heat exchanger above the bottom sleeve-supporting plate; and a liquid distribution box positioned above the upper tube sheet and a feed inlet to deliver a feed liquid to the liquid distribution box.
