Abstract In order to compare the effect of different coalescer on the oil content of the oil outlet of tubular oil-water separator, provide technical support for engineering design and selection, the concentration field and the oil content of the oil outlet of four different coalescers of the positive V-shaped inclined plate, the inverted V-shaped inclined plate, the traditional inclined plate and the snake-shaped back folding plate were analyzed by CFD method, the best structural parameters of the positive V-shaped coalescer in a single condition were investigated. Results show that in flow rate under study (0.05—0.35 m·s^-1), the positive V-shaped component has the best the oil content of the oil outlet among the four kinds of coalescer, the snake-shaped back folding plate and the inverted V-shaped inclined plate ranked second and third, respectively, the traditional inclined plate separation has the lowest effect; With the increase of inlet flow rate, the oil content of the oil outlet of four kinds of coalescers decreases correspondingly, the traditional inclined plate drop the fastest, the positive V-shaped inclined plate and the snake-shaped back folding plate have slowest decline, have little difference, while the inverted V-shaped inclined plate decrease speed is in the middle, the control variable method is used to determine that the oil content of the oil outlet is the highest when the distance between the positive V-shaped component and the wall is C=10 mm and the horizontal angle θ=60°.
