In textile industry, it is desired to make caustic soda solution containing 24% NaOH by mass for a mercerization process. Due to the very high heat of dissolution of caustic soda in water, the solution is prepared as follows; First in a dissolution tank caustic soda of 50 wt% NaOH was prepared by mixing 100 kg of solid NaOH with water. It was then fed to the dilution tank where a fraction of feed water is added to produce the desired solution. a) Calculate the amount of water required b) Calculate the amount of desired solution produced. c) Calculate the amount of 50 wt% NaOH solution produced. d) Calculate the amount of feed water that is bypassed to the dilution tank. e) Calculate the ratio of water that is bypassed to the dilution tank to that is fed to the process In textile industry, it is desired to make caustic soda solution containing 24% NaOH by mass for a mercerization process.
