In the process of natural gas exploitation

liquid water deposition will seriously threaten the gas transmission pipeline. As such

the gas-liquid separation equipment is widely used in the natural gas gathering system. To investigate the separation characteristics of the corrugated plate

which is viewed as an important separation element in the liquid separation side of the gas-liquid separation flash skid

an experimental platform for exploring the separation characteristics of baffles is constructed

coupled with the orthogonal experiment designed for different types of corrugated plate. The separation efficiency and pressure drop of the corrugated plate are taken as the test indexes. The main influencing factors and the best combination scheme are determined by analyzing the influence of the internal components at the liquid separation side on the separation performance under multiple working conditions at room temperature. The results show that the separation efficiency proves to be the best when the horizontal trapezoidal or honeycomb corrugated plate

deflector structural parameters of 180/102/105 or 120/102/105

liquid gas ratio of 2.083‰~2.917‰ and closed connecting pipe are combined. The corrugated plate type is seen as a vital factor affecting the separation efficiency. The pressure drop would be the smallest in the whole gas-liquid separation process when the honeycomb or vertical trapezoid corrugated plate

the deflector structural parameters of 180/102/105 or 120/102/105

the liquid-gas ratio of 3.750‰~4.583‰ and the closed connecting pipe are integrated. The above four factors exert no significant influence on the pressure drop.
