Liquid condensation in natural gas transmission pipelines commonly occurs due to both the thermodynamic phase behavior of natural gas mixture and the variations of pressure and temperature along pipeline. Condensation subjects the gas pipeline to two-phase transportation. Neither the point along the pipeline at which the condensate is formed nor the quantity formed is known a priori. Hence, compositional multiphase hydrodynamic modeling which incorporates the multiphase hydrodynamic model with the natural gas phase behavior model is necessitated to predict fluid dynamic behavior in gas/ condensate pipelines. In the present study, a transient compositional multiphase hydrodynamic model for transient gas/condensate two-phase flow in natural gas pipelines is proposed. The multiphase hydrodynamic component of the model is based on a well-posed two-fluid model.
