摘要
Chlorine emissions from cooling towers are emitted mainly as hypochlorous acid, not as molecular chlorine. Chlorine emissions from cooling towers in electric utilities in the U S are estimated to be 4,400 t/year. On a molar basis, molecular chlorine results in a greater increase in tropospheric ozone than hypochlorous acid. However, hypochlorous acid produces more ozone than molecular chlorine when an equal amount of chlorine is present on a mass basis.
