Alve is PHA-543613 Technical Information opened, the oil phase will also enter the gas
Alve is opened, the oil phase may also enter the gas channel and discharge. From this point, it can’t enter the central pipe, and so the oil holdup in the central pipe declines. In accordance with the above information analysis, the applicable array of DGLS for oil as ater multiphase flow is 20 m3 /d 50 m3 /d.Appl. Sci. 2021, 11, x FOR PEER REVIEW13 ofAppl. Sci. 2021, 11,it is in an oil-in-water state inside the figure. Because the flow rate increases, the oil volume inside the central pipe also increases. Visual observation indicated that the DGLS does not separate 13 of 21 the oil in the fluid medium, and oil droplets do not accumulate under the collection umbrella. Rather, the distribution of oil inside the central tube is similar to that within the wellbore.(a)(b)(c)(d)(e)Figure 7.
