(continued from issue 100(2002)26, pp 62-63) A 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. Two-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 to hydrocarbon systems was questionable at best. Application of these correlations can lead to results which are grossly in error. Because of this, two-phase equipment can be designed badly, leading to unnecessary costs or even failure. This is the second of two articles that present new and simpler pipeline design approaches.
