The Effect of Condensate Accumulation in the Gas Pipeline on the Transport Pressure

Unlike natural gases, the long-distance transportation of associated gases in a monophase state is impossible. The increase in export gas volumes has made it necessary, under modern conditions, to collect, process, and transport associated gases produced alongside oil to their final destinations. Compared to dry gases, the collection and transportation of associated petroleum gases are accompanied by several challenges. One such challenge is the filling of the pipeline with condensate due to the condensation of associated gas. This requires the calculation of gas condensation along the pipeline route. The article investigates the changes in the transportation pressure of a gas pipeline at various gas flow rates, depending on the degree of pipeline filling with condensate. It was found that during the multiphase flow of associated gas, an increase in pressure is observed in the gas pipeline due to the accumulation of condensate.
