Question 4

Saturated steam at 227°C is used in a heat exchanger to preheat a reactor feed stream.

(a) If the condensate (saturated liquid) is removed from the heat exchanger at 152°C and the flow rate is 1000 kg/h, how much heat (kJ) is transferred from the steam to heat up the reactor feed stream in one hour?

(b) How much additional steam would be required if the condensate is removed at 227°C, instead of 152°C, for the same exit reactor feed stream
