Laboratory Studies of Gas Tracers for Reaeration

摘要: Laboratory studies were conducted to determine the rates at which ethylene and propane desorbed from a water bath relative rate oxygen was absorbed by same water. The ratios between absorption coefficient hydrocarbon desorption are 1.15 1.39 for propane, respectively. These serve as basis tracer technique measuring reaeration coefficients of streams. Comparison 2-parameter 3-parameter procedures show that procedure is able fit data better in terms root-mean-square error. However, estimates saturation concentration dissolved with unrealistic. Therefore, fixed literature value specific temperature corrected barometric pressure used. also used equilibrium zero.
