Natural gas online analyzer
The natural gas online analysis system mainly consists of gas supply system, sampling system, sample pretreatment system, online gas chromatograph, etc. The sample gas is taken out by the sampling system and enters the online gas chromatograph through the sample pretreatment system to remove impurities, oil, stabilize pressure, and stabilize flow. It passes through several parts such as the chromatographic injector, chromatographic column, detector, and data processing unit. After data processing, it is converted into a concentration signal and then transmitted to the remote flow computer for natural gas composition analysis.
