One hundred kilograms per hour of a solution that is one-fifth by mass KCl and the rest water is concentrated by removing 60 kg of water per hour in an evaporator. Part of the concentrated stream leaving the evaporator is recycled and joins the fresh feed at the evaporator inlet. The other part of the evaporator outlet stream is fed into a filter- dryer in which the KCl-water mixture is further-concentrated to 98% w/w KCI. The stream entering the evaporator contains 70% w/w KCA Draw the process flow diagram showing all flow rates and compositions given. [4 marks] (a) Calculate the flow rates and compositions of the following material streams: [3 marks] [3 marks] [8 marks] [2 marks] (b) Concentrated (98% w/w) product Water leaving the filter-dryer. Recycle stream. Streams entering and leaving the evaporator.
