Abstract
A heat exchanger is presented that provides for mixing of a process fluid to prevent localized spikes in temperatures. The heat exchanger includes a mixing chamber within the exchanger, where a first process fluid passes from process tubes after being partially heated. The heat exchanger further includes an intermediate shell for passing a second process fluid into the fired heater and for exchanging heat with the first process fluid. The fluid flows from the mixing chamber to other process tubes for further heating.
Claims16
An apparatus for combining heat exchange and mixing, comprising:
- a plurality of first process inlet tubes, where each inlet tube has an inlet and an outlet;
- a mixing chamber with a plurality of inlets and outlets, where each first process inlet tube outlet is in fluid communication with a mixing chamber inlet;
- at least one first process outlet tube, where the outlet tube has an inlet in fluid communication with a mixing chamber outlet, and an outlet;
- a housing surrounding the first process inlet tubes, the mixing chamber and the first process outlet tubes;
- and
- at least one heating source for heating the first process inlet and outlet tubes.
