Model aids design of three phase, gas-condensate transmission lines

A steady-state analytical model describing the problem of gas condensation and resulting hydrodynamics in three-phase flow pipelines has been developed and proven by comparison to an operation of similar flow circumstances.The model demonstrated that a point exists in pipeline where a maximum amount of liquid occurs and that this point is not fixed but strongly depends on the inlet gas-flow rates.The model is an appropriate tool for engineering design of pipelines carrying gas and condensate, serving as both a predictive and a design tool.The study that developed this model used continuity and momentum equations to calculate pressure drop and liquid holdup in three-phase flow pipelines.El...
