Experimental study of order and constant rate of chlorine removal reaction using ion exchange resin

Abstract

AbstractIn this research, a strong anionic resin was prepared to remove chloride ions. This study was performed in a laboratory pilot to evaluate effective parameters such as temperature, amine flow rate, pH, chloride ion concentration and concentration of resin caustic. The purpose of this work is to determine kinetics of the resin reaction and determination of the optimal operating conditions in order to achieve maximum saturation. This study shows that volume of distilled water passing through resin to eliminate alkalinity at temperatures 40 °C, 50 °C and 60 °C is equal to 5500 ml, 5000 ml and 7000 ml, respectively. This work states that a temperature 50 °C is more appropriate than other temperatures. The results of this research show that volume of caustic for resin recovery is 8.5 L at a temperature of 50 °C. This study shows that amount of distilled water to eliminate alkalinity of the resin is equal to 5 L. Results show that the order of reaction to chloride ion concentration is equal to 0.794 and reaction constant is equal to exp (−1.8753).
