•White Paper: Research Developments In Wet Gas Metering With McCrometer V-Cone® Meters
By McCrometer, Inc.
At the 2002 North Sea Flow Measurement Workshop (NSFMW) NEL and McCrometer jointly presented the results and analysis of the UK's Department of Trade and Industry (DTI) fundedV-Cone® meter wet gas flow tests on the NEL Wet Gas Loop. Two 6" beta ratios (0.55 and 0.75) were tested and for eachmeter the parameters influencing the differential pressure reading with wet gas flowswere identified and found to be similar to other Differential Pressure (DP) meters. Correlationswere then offered that would correct for the V-Cone meters' liquid induced error inthe gas flowrate prediction for a known liquid flowrate or liquid to gas flowrate ratio.
This paper briefly summarises the V-Cone meter technology and then discusses the results of repeat wet gas flow tests at NEL in May 2003 (at nominally 15 and 60 Bar) for the 0.75 beta ratio V-Cone meter, to show the repeatability of the meter with wet gas flows and the reliability of thepreviously published wet gas flowcorrelation within the NEL parameter range. This paper thendiscusseswet gas flow testing done on a 4", 0.75 beta ratio V-Cone meter at CEESI in October 2002 across a different parameter range to that of NEL and compares the 0.75 beta ratio data sets at the two test facilities. The V-Cone meters 0.75 beta ratio correlation is then applied to theindependent CEESI wet gas flow data set to investigate the applicability of the NEL data based correlation out with the NEL test range. With the correlations applicability shown, a discussion on the industrial advantages of a proposed Tracerflowand V-Cone meter combination is given. This is followed with new data showing the 0.75 beta ratio V-Cone meters performance at greaterLockhart-Martinelli parameters than previously tested (up to 0.5). A new correlation is discussed for this expanded range and the results of applying this new correlation to the NEL data set arepresented. Finally, a rare field test showing the performance of a Wafer-Cone®meter with wet gas flow is discussed.
