Monitoring and Analyzing the Associated Gas Flaring Process Using Multivariate Control Charts

Abstract

The process of burning related gases pollutes the environment and makes global warming worse. Additionally, it is a waste of a significant energy source. In this research, the associated gas burning processes in Iraq were studied and analyzed over short, medium, and long terms using control panels. (Kernel) and panels (KNN) using comparison criteria such as mean range length (ARL), absolute value of bias (BALR), and standard error of average range length (SEARL) and using several distributions at different levels of significance and sample sizes. The results of the comparison demonstrated the preference of the kernel control panel over the other panels. Additionally, in the panel's application to variables representing the volume of related gases burned in Iraq's oil companies, it was found that the gases produced by oil well flares were noticeably out of control in the short term, as It is clear that the process can get out of control at the beginning of the monitoring process, but when monitoring in the medium term, the results indicate a decrease in the process getting out of control, and the process may get out of control in the middle of the monitoring period. Finally, when observing the associated gas combustion process in the long term, the process will be out of control at the end of the monitoring period.
