ABSTRACT:
Heat exchanger apparatus for quenching hot hydrocarbon fluid feeds, of different compositions, so as to minimize coking including a shell, and baffle structure in the shell, defining spaced first and second chambers and primary inlet and outlet ports to flow the fluid to and from the shell via the two chambers, the shell and baffle structure also defining a third chamber between the first and second chambers, with secondary inlet and outlet ports communicating with the third chamber to flow quench fluid to and from the third chamber, and pipes of different bore sizes extending through the third chamber, and communicating between the first and second chambers, for passing the hydrocarbon fluid in a selected path or paths via the pipes and first and second chambers, in flowing between the primary inlet and outlet ports.
