摘要在实验室规模上研究了半连续搅拌反应器中水吸收臭氧的传质过程。实验研究使用一个完整的阶乘计划显示了搅拌速度和气体流量的主要影响,并在传质系数,k1a的相关性的结果。臭氧在水中的溶解度是通过评估不同温度(20 ° C和50 ° C)、pH值(2和7)和t常数离子强度(0.13)的表观亨利定律常数来估算的。
Abstract Mass Transfer of ozone absorbed by water in a semi-comtinuous stirred reactor is studied at the lab scale. Experimental investigation using a complete factorial scheme shows a predominant effect of agitation speed and gas flow and results in a correlation for the mass transfer coefficient, k1a. Solubility of ozone in water is estimated by evaluation of an apparent Henry's law constant for different temperatures (20* and 50*C), pH values (2 and 7) and a t constant ionic strength (0.13).
