| dc.description.abstract | An experiment was conducted to evaluate the operational parameters of an evaporation unit which concentrate dilute caustic soda from the mercerizing operation wastewater unit of a textile mill. The concentration of caustic soda for the mercerizing operation was optimized before recovery and optimum concentration of 20-23% was attained. In this process, the concentration of caustic soda in the wastewater was raised to the optimized range 20-23 w/w % by evaporating the water from the dilute solution collected from the mercerizing effluents which contain 5 w/w% caustic soda. The process unit used for this purpose consists of an evaporator, separator, steam generator, condenser, feed vessel, storage tank and vacuum pump. Parameters including the amount of mass condensate, the amount of mass concentrated, temperatures, evaporator pressure, heating steam supply pressure and concentration change of caustic soda solution were measured. From these, the rate of evaporation, and concentrating capacity of the evaporation were determined. From the experiments, it was found that the rate of evaporation ranged from 2.24 kg/hr to 6.41 kg/hr with an average of 5.71 kg/hr. | en_US |
