A stream of CO2 at pressure 1 bar, flowing at 10 mol/s, from 150°C to 300°C is to be heated in a counter current heat exchanger. To do this task a stream of high-pressure steam available at 40 bar and 400°C is used, as shown in the following figure. The entire system is well insulated, as shown. It is undesirable for the steam to condense in the heat exchanger tubes. Assume the pressure of each stream stays constant as it flows through the heat exchange What is the minimum volumetric flow rate, in m3 /s, required of the inlet steam to keep it from condensing at the exit?
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
