Hydrocarbon Dew Point has always been a vital operational parameter and but it is becoming a critical tariff parameter for the natural gas industry. Measuring it must be done accurately or even small errors can jeopardize tariff compliance and potentially result in shutins. If liquids build up in the pipeline, this can damage compressors and other in-pipeline equipment. Overcompensation for poor analysis techniques, or a less than optimal choice of instrumentation, adds significantly to operational costs. The focus of this paper is to identify the best practices for measuring the hydrocarbon dew point (HCDP) in natural gas. The three most popular methods for measuring this parameter will be discussed
