Multiphase flow theory is widely used in the field of oil and gas exploitation and transportation engineering, especially in the surface gathering and transportation system. Multiphase pipeline,  refers to the pipeline that transports the mixture of oil, gas and water (sometimes with solid impurities such as mud and sand) produced by one or more oil (gas) wells, is widely used. In addition to all the characteristics of a two-phase mixing pipeline, it also has the following features: 1. It will hasten the deterioration of the pipeline's inner wall. 2. The light components in water and natural gas may form hydrate and obstruct the pipeline under high pressure and low temperature. To prevent hydrate formation in multiphase mixed transmission pipelines, solvents such as methanol or ethylene glycol are frequently introduced into the fluid. Many academics have spent a lot of time and money researching mixed transportation technology and related equipment up to now. The purpose of this special issue is to collect the latest achievements in the research and application of multiphase flow theory in oil and gas gathering and transportation process. Potential topics include but are not limited to:


· Thermophysical properties of multiphase flow

· Mathematical model of multiphase flow

· Process calculation method of multiphase mixed transmission pipeline

· Multiphase flow measurement and testing technology

· Analysis of multiphase flow in gas-liquid-solid pipeline

· Common equipment and automation technology in multiphase pipeline

· Multiphase flow erosion and corrosion

· Control of severe slug flow in multiphase riser

· Diagnosis and control of multiphase flow thermophysical processes

· Hydrate formation and flow guarantee

· Leakage and detection of multiphase pipeline

· Heat transfer issues in Natural gas liquefaction

· Multiphase flow in oil and gas treatment unit

· Multiphase flow in carbon dioxide and hydrogen pipeline

    Abstract The coupled formation of wax crystals and hydrates is a critical issue for the safety of deep-sea oil and gas exploration and subsea transport pipeline flow. Therefore, this paper conducts an experimental study on the characteristics of methane hydrate formation in a water-in-oil (W/O) system with different wax crystal contents and explores the influence of different initial experimental pressures on the induction period and maximum rate of hydrate formation. The wavelet function was introduced to process the reaction rate and calculate the maximum speed of hydrate formation. Notably, the higher the pressure, the smaller the… More >

    Abstract In the natural gas liquefaction process, the mixed refrigerant natural gas liquefaction process is widely used in LNG liquefaction plants because of its advantages of low energy consumption. This paper focuses on the influences of important parameters in the C3/MRC liquefaction process, that is, the comparison between propane precooling temperature and the number of moles of methane in mixed refrigerant, power consumption and loss. In addition, the total process was optimized with the optimizer and manual adjustment in HYSYS software to minimize the total power consumption. The results show that with increasing propane precooling temperature, More >

    Abstract Hydrogen energy is a crucial carrier for the growth of the energy system and its low-carbon transformation. Using natural gas as a carrier of hydrogen transport and the natural gas pipeline network for transportation is a significant step toward realizing large-scale and long-distance hydrogen transport. Hydrogen-mixed natural gas is mainly separated into hydrogen and natural gas by physical methods at present. High purity of hydrogen recovery, but the recovery rate is low. At the same time, compared with natural gas, liquefied natural gas is more economical and flexible. This study analyzes three typical cryogenic separation… More >

    Abstract Supersonic separation technology is a new natural gas sweetening method for the treatment of natural gas with high CO2 (carbon dioxide) content. The structures of the Laval nozzle and the supersonic separator were designed, and the mathematical models of supersonic condensation and swirling separation for CO2-CH4 mixture gas were established. The supersonic condensation characteristics of CO2 in natural gas and the separation characteristics of condensed droplets under different inlet pressures were studied. The results show that higher inlet pressure results in a larger droplet radius and higher liquid phase mass fraction; additionally, the influence of centrifugal force More >
