Laboratory evaluation of operating conditions for chloride removal from diethanolamine using ion exchange resin and introduction of optimal parameters

Abstract In this study, a strong anionic resin was used to remove the chloride ion in diethanolamine of sweetening unit gas refinery. A laboratory pilot has been investigated as resin-filled bed evaluate reaction temperature, concentration, saturation, recovery rate, optimal flow hydrogen strength and performance work. The saturation time, capacity resin, temperature changes concentration output stream from were determined research. Finally, amount water regulate pH 4% sodium hydroxide solution recycle calculated. It found that one liter is able absorb 20.77 g chloride. 50 °C considered exchange by comparing caustic consumption for regulation neutral acidity, respectively. 4 wt.% at 134 obtained equal 8.5 5 L,
