Application Note: Analysis Of Pipeline Quality Gas Using A C9+ Analysis
Emerson Process Management's on-line chromatographs provide custody-transfer measurement of energy content in natural gas. To determine this heating value component, first we must determine component concentrations. In a standard C6+ application, this analysis is performed using two valves in a single oven (12-minute analysis time) or three valves in a single oven (four-minute analysis time). To perform this analysis to C9+, five valves are used in two different ovens (five-minute analysis time). The results from both detectors are combined in post-analysis calcuations and reported together.
