Experimental Investigation of Ion Mobility Measurements in Oxygen under Different Gas Pressures

چکیده
In this paper, measurements of ion mobility were performed in oxygen at gas pressures of 44.52 101.19 kPa using the drift tube method. Over this pressure range, mobility values were within the limits of 1.796 to 3.821 cm2·V·s were determined and ion mobility shown to decrease nonlinearly with increasing gas pressure towards a certain level of saturation. Ion mobility measured in air was lower than that measured in oxygen at the same gas pressure. Finally, a parameter correction method for calibrating the relationship between the ion mobility and gas pressure in oxygen was proposed.

To provide supplementary oil recovery after the primary and secondary processes, enhanced oil recovery (EOR) techniques are introduced. Carbonated water injection (CWI) as an EOR method can improve sweep efficiency and the risk of gas leakage. On the other hand, the interfacial tension (IFT) is one of the key factors which can affect fluid displacement during the process of CWI greatly. Therefo...
