(a) An incoming stream of 1500kmol/min consists of saturated water with 65% liquid water and 35% steam at 40 bars. This steam is heated at constant pressure to 600°C. Using the steam tables, what is the heat transfer requirement for this step in kW? (Note: Steam tables in the bottom page) (b) This steam is then compressed isothermally to steam at 200 bars in a second step. What is the heat transfer requirement for this step in kW?
