Ethylene mass flow measurements with an automatic CO(2) laser long-path absorption system.
A computer controlled CO(2) laser long-path absorption system has been used in a field experiment to measure the total emission of ethylene from a petrochemical factory. The ethylene concentration was measured along eight measurement paths at different elevations. Simultaneously meteorological data were collected. From these data we have calculated the mass flow from the factory. The result of the calculations agree well with the value estimated at the factory using conventional methods.
