In downstream processing of gluconic acid, concentrated fermentation broth containing 20% (w/w) gluconic acid is cooled in a heat exchanger prior to crystallisation. 2000 kg h-1 liquid leaving an evaporator at 90°C must be cooled to 6°C. Cooling is achieved by heat exchange with 2700 kg h-1 water initially at 2°C. The final temperature of the cooling water is 50°C.
Assume (heat capacity of gluconic acid is 0.35 cal g-1 °C-1).
h (liquid water at 90°C = 376.9 kJ kg-1)
h (liquid water at 6°C = 25.2 kJ kg-1)
h (liquid water at 2°C = 8.4 kJ kg-1 )
h (liquid water at 50°C = 209.3 kJ kg-1)
h (gluconic acid at 90°C=0)
How much heat is removed to the cooling water?
