trace gas analysis in hydrocarbons - application note - 3

WHY DO YOU NEED TO CONTROL TRACES IN HYDROCARBONS PROCESSES? In many petrochemical applications, some gas components can be found at trace level. Their concentrations can fluctuate over time, and are depending on process parameters, or process feed. Species like H2S, NH3, or H2O, can be considered as impurities (corrosive, toxic, etc.), and are often tracked in these gas matrices to insure the quality of the final gas product and the efficiency of the production process.
