从水中的挥发性有机化合物（VOCs）的空气汽提优化，同时考虑资本和运营成本。通过Onda的传质系数关联式和计算机模拟，建立了五种代表性VOCs的最佳水负荷率和空气-水比。整体处理成本似乎是相对不敏感的最佳区域附近的操作变量的变化，但迅速增加的条件偏离最佳区域。还观察到，总处理成本对资本成本非常敏感，但不受电力成本的显著影响。随着温度的升高，处理成本几乎呈线性下降。
The air stripping of volatile organic chemicals (VOCs) from water was optimized by taking into account both capital and operating costs. By using Onda's correlation for mass transfer coefficient and computer simulations, optimal water loading rates and air-to-water ratios were established for five representative VOCs. The overall treatment cost appeared to be relatively insensitive to changes in the operating variables in the vicinity of the optimum region but increased rapidly as the conditions deviated from the optimum region. It was also observed that the overall treatment cost was very sensitive to capital cost but not significantly affected by power costs. The treatment cost dropped almost linearly as temperature increased.
