Question

Question 5 Hydrochloric acid is produced by absorbing gaseous HCl in water at near atmospheric pressure. A packed bed absorber is used to absorb 200 kg/h of HCl gas using 800 kg/h water, both entering the column at 25°C a) Calculate the heat removal rate required to maintain the operating temperature of the absorber at 25°C (5 marks) b) If the cooling system fails and the absorber operates adiabatically, what will be the final temperature of the acid produced? If the operating pressure is 1. bar, would it still be possible to produce 1000 kg/h acid? (6 marks) *Note: Assume that the specific heat capacity of the solution is the same as that of water
