Wet Gas Defined Wet gas flow measurement is gaining attention at present due to its importance in the oil and gas industry. Two examples of wet gas in a production system are separator and well-head flow lines. The term wet gas, however, is rarely defined. A loose definition is the flow of gas--typically natural gas--containing a small amount of liquid. In effect, wet gas can be considered a subset of two-phase flow. The question is where does wet gas end and two-phase flow begin? In 1997, a consensus was that wet gas was "a gas flow with liquid contents less than 5% by mass." Last year, the envelope was stretched to include liquid mass fractions even up to 50%. This can mean liquid volume fractions up to 5%. The answer has still not been determined. But with the increasing emphasis on wet gas measurement, the need to find an answer is more urgent than ever. For more information about wet gas measurement, check out McCrometer's paper presented at Norflow 99, www.mccrometer.com/library/ to download (document # 24508-49). The paper, entitled "V-Cone, an Alternative to Orifice Meter in Wet Gas Applications", discusses the use of the V-Cone differential pressure flowmeter to measure wet gas flow. This paper is located in the "Literature on V-Cone flowmeters" section under the Independent & Company Research heading. The next oil and gas industry event that McCrometer will attend is the 75th International School of Hydrocarbon Measurement, May 16 to 18, at the Tulsa Convention Center in Tulsa, Oklahoma. |
