The exploitation of natural gas deposits necessitates the transportation of extracted fluids through pipelines to treatment facilities, which include not only methane but also ethane, liquid fractions of propane, butane, hexane, and occasionally salt water. To ensure that natural gas is delivered for consumption free of water and oil liquids, the flow rates from gas extraction wells must be managed in two-phase mixing pipelines directed to a single treatment site. This article investigates the influence of mixing pipe diameter on gas flow. The research explores the transport conditions under which gases and liquids coexist, and the resulting pressure variation that impacts the separation of the liquid phase from the gaseous phase. Various flow regimes are examined, including dispersed bubbles, elongated bubbles, stratified flow, wave flow, plug flow, and ring fog, depending on the gas-liquid ratio. The findings highlight the complexity of calculating pressure drops of two-phase fluids due to changes in pressure, temperature, and empirical evaluations of liquid retention in pipelines, alongside the assessment of energy transfer between phases. The results underscore the critical role of mixing pipe diameter in optimizing gas flow for efficient natural gas extraction.
