Multiphase flow occurs in various hydrocarbon production systems including the transportation of wet gas through pipelines and can result in field operation issues. Several factors contribute to liquid condensation in pipelines including a multicomponent mixture of wet gas, the pipeline profile and the variation of pressure as well as temperature along the pipeline. Liquid accumulation (holdup) due to condensation in pipeline can increase the pressure losses therefore reducing the volumetric capacity of the pipeline. To minimize the problem caused by pipeline liquid holdup, a simulation can be utilized to predict gas condensation in the pipeline. An accurate prediction can indicate where and how much liquid will form. This information will assist in the liquid collection strategy and to determine cleaning (pigging) schedules needed to maintain the pipeline efficiency. In this paper, a case study is simulated for a steady state and transient model systems. Both system models demonstrate how to manage the wet gas pipeline and maintain the system in equilibrium.
