| Abstract: | Using a predicted value of the liquid phase diffusivity, the Chiang and Toor model is shown to give a good estimate of the measured rate of absorption of hydrogen chloride by ethylene glycol. A liquid surface temperature rise of 20°C is calculated. Unlike the previously tested ammonia-water system, temperature and volume effects do not compensate, and the absorption rate in this system is considerably higher than the isothermal prediction. |
