Question:
A heat exchanger is used to transfer heat from a steam stream to a chlorine gas stream. 100 kg of steam at 1 bar and 250*C enters the heat exchanger and leaves the exchanger as saturated steam at 1 bar. Chlorine gas enters the exchanger at 1 bar and 40*C and leaves the exchanger at 136*C. Assume the heat exchanger is adiabatic.
a) What is the specific enthalpy of outlet chlorine gas stream?
b) How many moles of chlorine gas enter the heat exchanger?
c) What is the ratio of the volume of inlet steam to the volume of inlet chlorine gas? Use the ideal gas law to calculate the volume of chlorine entering the process.
d) How much heat is transferred from the steam stream per cubic meter pf chlorine gas?
