Rate, the bubble size in the inlet on the wellbore elevated. Additionally, the bubbles discharged through the exhaust channel and gradually expanded but remained part of the G/W bubble flow. At the similar time, observation of your central pipe showed that its gas content material had also improved in conjunction with the raise in total flow. The simulation analysis results are shown in Table 2 through the numerical simulation on the total flow of 20 m3 /d 60 m3 /d. DGLS can reach fantastic gas iquid separation efficiency within the range of 20 m3 /d 30 m3 /d, and its error is within the allowable range (according to the conditions (e)). Using the boost in flow rate, the gas holdup in the central tube also increases. Although the array of gas holdup in the central tube is smaller, the DGLS’s gas iquid separation efficiency drops. The bigger the total flow rate, the extra complex the flow state, plus the less SC-19220 Antagonist pronounced the gas iquid separation impact. When the flow is 20 m3 /d, it can attain a very high gas iquid separation efficiency. Nonetheless, it can not meet the demand following greater than 20 m3 /d, as well as the gas separation impact can not be achieved at this level.Table 2.
