In an ammonia-absorption system with an analyser but with- out a dephlegmator the following data are given: Condenser pressure Evaporator pressure 20.3 bar 2.1 bar Generator temperature 156C 40C Absorber temperature Determine, per unit mass of the vapour distilled: (a) Specific solution circulation rates. (b) Temperature lo, at inlet to evaporator if the liquid from the condenser is cooled by 13C in the liquid-vapour heat exchanger. (c) The refrigerating effect if the maximum refrigeration temperature is 5C. (d) The heat transfer in the liquid-liquid heat exchanger. (e) The heat added in the generator. (f) The pump work. (g) The coefficient of performance. (h) The heat rejected in the absorber and condenser. (i) Energy balance of the system.
