![]() Devices capable of determining the physical dew point of either hydrocarbon or water in natural gas, and those devices that can measure the concentration of water in a natural gas sample.Īnalyzers capable of measuring the dew point temperature directly are based on chilled mirror technology and are sometimes referred to as ‘first principle’ devices. There are two classes of measurement devices. The dew point temperature refers to the equilibrium established over a liquid phase. At this temperature, the gas exists in equilibrium with a condensed phase. The dew-point of a gas is a physical property - the temperature at which the sample gas becomes saturated and condensation first begins to appear. Tunable Diode Laser Absorption Spectroscopy Water Dew Point Measurement, the different technologies that can be utilized (listed below), and the key requirements for using a Sample Conditioning System. In this seven-part series we’ll discuss Water Concentration vs. There are several ways of determining the water vapor concentration in natural gas. The formation of hydrocarbon liquids (condensate) due to the presence of heavier hydrocarbons in the natural gas can lead to increased pressure drops in the pipeline system, flooding, and safety hazards associated with liquids such as hot spots on compressor turbine blades. Furthermore, water vapor present in natural gas streams affects the overall quality of the gas and reduces the energy or heat content (BTU value) of the gas, making the measurement of water vapor in natural gas an important requirement to producers, suppliers and end users in the industry.Įqually important is the need to determine the hydrocarbon dew point temperature in a natural gas sales pipeline network. High levels of water vapor in a natural gas stream can lead to problems, including the formation of hydrates and the contribution to corrosion of plant and equipment. The determination of water vapor (water dew point) is crucial in the processing, custody transfer, and transport of natural gas. This is part one of a seven-part series about measuring water vapor and hydrocarbon dew point in natural gas. 914 Continuous Emission Monitoring System.241CE II Hydrocarbon Dew Point Analyzer.IPS-4 Integrated Photometric Spectrometer. ![]() Standard Bureau of Mines Dew Point Tester.
