Abstract: Obtaining a representative gas phase sample of natural gas sources containing entrained liquid has caused many problems. A new technology was developed which consists of a technique and hardware for sampling natural gas having entrained liquid. It removes the liquid under pipeline pressure and temperature conditions thereby preventing gas phase composition changes that would otherwise occur. After the liquids are removed the pressure is regulated in a manner which prevents excessive cooling and possible condensation of some gas phase components. The hardware can be inserted/retracted at normal pipeline pressures to facilitate maintenance. The technology applies to sampling for BTU determination, moisture and H2S analysis.
