Claim 2:
3. A method of processing a process fluid that comprises dissolved gas, the method comprising:
supplying the process fluid and a heat transfer fluid to a process fluid heat exchanger whereby, due to heat transfer between the process fluid and the heat transfer fluid, a temperature of the process fluid is increased and at least some of the dissolved gas within the process fluid is removed, the process fluid exiting the process fluid heat exchanger as a heated process fluid;
providing one or more partially perforated baffle plates in fluid communication with a process fluid inlet of the process fluid heat exchanger, wherein the one or more partially perforated baffle plates are configured to direct a flow of the process fluid into a lower portion of the process fluid heat exchanger;
fully submerging the process fluid heat exchanger by using an overflow weir;
passing the heat transfer fluid that exits the process fluid heat exchanger through an expansion device so as to produce a post-expansion heat transfer fluid; and
supplying the post-expansion heat transfer fluid and the heated process fluid to a heat recovery heat exchanger whereby, due to heat transfer between the post-expansion heat transfer fluid and the heated process fluid, a temperature of the heated process fluid is decreased and a temperature of the post-expansion heat transfer fluid is increased such that the post-expansion heat transfer fluid that entered the heat recovery heat exchanger exits the heat recovery heat exchanger as a heat transfer gas and the heated process fluid that entered the heat recovery heat exchanger exits the heat recovery heat exchanger as a cooled process fluid.
