..., U.S.A., fax 01-713-586-5955. ABSTRACT When wet gas is transported in a pipeline, liquid (condensate and water) will drop out due to temperature and pressure changes along the pipeline. The prediction of liquid holdup inside a pipeline is very important, as it will affect the prediction of pipeline...
