“…However, the intention for the removal of a high percentage of CO 2 along with NGL stabilization is rarely found in the literature [10][11][12][13][14][15][16]. In the present research work, a maximum 15 mol% CO 2 concentration in the feed stream of the stabilizer unit is studied to achieve CO 2 -free condensate with stabilizer unit parameters of a 7 psia Reid vapor pressure (RVP), however, the maximum CO 2 in feed reported in the literature [19] is only 7.47 mol%.…”

“…Among these, oxidative desulfurization is a commercially viable method to decrease the total sulfur content from 8500 ppm to less than 700 ppm by eliminating all hydrogen sulfide with mercaptans and severely reducing other heavy sulfur-containing compounds. [12]. In case of defects in the cooling system at the top stage of debutanizer column, modification of LPG and NGL production has been discussed to avoid flaring by selecting a reflux stream temperature of 55 • C [13].…”

Stabilization of condensate is a highly energy-consuming process compared to other oil and gas processes. There is a need to reduce this energy consumption. Therefore, the present work aims to simulate the stabilization unit in terms of available energy and on-spec stabilized condensate products. Natural gas condensate liquids (NGL) need to be stabilized by eliminating lighter hydrocarbon gases and acid gases before being sent to the refinery. Stabilized NGL has the vapor pressure determined as a Reid vapor pressure of 7 psia, showing that light components did not evolve as a separate gas phase. Stabilization and CO2 removal was performed through the distillation method by heating and pressure reduction using steady state and dynamic simulation through Aspen HYSYS. Different process alterations around the exchanger and column have been studied based on the utilities available for the stabilization and CO2 removal process. Sensitivity studies, including the impact of CO2 concentration, the temperature at the inlet of the stabilizer flash separator, and the dynamic simulation for the PID controller, have been performed to analyze the impact on the process parameters, such as Reid vapor pressure (RVP) and CO2 of the rundown air cooler and heat duties of the exchangers. Actual plant data have been used for the validation of process simulation values for the accuracy of the condensate stabilization unit model. Based on the scenarios analyzed, it can be concluded that the nitrogen stripping method achieved 7 ppmv CO2 and 7 psia RVP in the condensate from the cooler outlet, while a variation of 29 bpd was observed for the stabilized condensate flowrate throughout all scenarios with data validation showing 0.24% discrepancy between Aspen Hysys data and actual plant data.

Petroleum, oil and lubricants (POL) is critical to the functioning of oil equipment. It is very important to maintain the quality of POL consumption data of oil equipment. High-quality POL consumption data provide reliable datasets for computing the annual POL supply quota of oil equipment and improving the energy efficiency of such equipment. Based on the data analysis platform SPSS, this paper designs a hybrid quality control strategy called SEIB-K for POL consumption data of oil equipment, which couples the expectationmaximization algorithm with multiple imputations (EI), box plot (B), and kappa coefficient (K). The SEIB-K can systematically analyze the quality of actual POL consumption data, identify the missing items, abnormal items and contradictory items. Example analysis shows that our strategy could significantly improve the quality of POL consumption data. The research results provide a technical support for accurately determining the annual POL supply quota of oil equipment.
