Abstract
The invention is a method for operating a heat exchanger in a power plant by pumping a heat exchange fluid around a set of tubes in the first heat exchanger; increasing the heat exchange fluid temperature and cooling the compressed heated air; splitting heated fluid flow into a second and third heat exchanger and a vessel; injecting a hydrocarbon flow into the set of tubes in the second heat exchanger; flowing the heated fluid into the second heat exchanger transferring heat from the heated heat exchange fluid to the hydrocarbon flow whose temperature increases between 90% and 500%; flowing the cooled heat exchange fluid to the vessel; flowing the heated fluid from the first heat exchanger to a third heat exchanger and cooling the excess heated heat exchange fluid; and using the vessel to accommodate thermal expansion of the fluid.
