Abstract

Measurement of the hydrocarbon dew point of natural gas is crucial when determining whether gas can be transported safely through national and international pipeline networks.
This report summarises the results of a study undertaken to compare the performance of direct and indirect methods for determining the hydrocarbon dew point of a wide range of real and synthetic natural gases. The results obtained from six analytical methods (one automatic chilled mirror instrument, one manual chilled mirror instrument, two laboratory gas chromatographs and two process gas chromatographs) are presented and the comparative results are compared in detail.
The conclusions from the work discuss the relative performance of the different methods and consider how they vary when used with real and synthetic gases of different compositions. The difficulties inherent in measuring a ‘true’ value of hydrocarbon dew point are also discussed.
