New Correlation predicts liquid holdup in gas-condensate pipeline

Pipeline Design Tools - ConclusionA simple-to-use correlation has been developed which better predicts liquid holdup in gas-condensate transmission, two-phase flow pipelines. Research for the correlation is based on data from Iran's Kangan gas field. Click here to enlarge imageTwo-phase flow pipelines need accurate calculations for pressure drop and liquid holdup in order to size properly the lines and equipment.Until now, however, the estimation of two-phase flow liquid holdup relied on methods which are either empirical or semiempirical. These correlations were based on very limited data obtained from small-diameter, air-water systems.Extrapolation of these data to larger lines and...
