Summary Problem Discussion Consider the heat exchanger shown in the figure, it is required to control the outlet temperature of process fluid, T, by manipulating the steam flow, RV. Please design the relevant control schemes on the diagram for the following cases: Case 1: both of the flow, RF, and steam inlet pressure, PV, are stable。 TRVRF , TiS t e a mC o n d e n s a t eP r o c e s s F l u i dPVTmCase 2: RF is stable, but PV varies frequently。 Case 4: both of PV and RF varies frequently.
