Abstract. Natural gas is widely used in various applications including power generation and chemical industry. However, the natural gas from upstream contains several hazardous acid gases such as Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2) which pose risks to both human health and the environment. Therefore, acid gas removal process is pivotal for purifying the natural gas before being delivered to the end-users. This paper aims to investigate the colleration between different solvent components used in absorption-based acid gas removal units. The analysis employs three correlation approaches: Pearson, Spearman, and Kendall. The data was simulated using a Hysys flowsheet by varying the type of solvent blends and compositions. The results indicate that the solvent blends MDEA+PZ and MDEA+DEA exhibit the highest correlation with CO2 removal, achieving a correlation value of -0.91. For H2S removal, the MDEA+SFL blend shows the highest correlation, with a value of -0.74. These findings suggest that specific solvent blending can significantly enhance the reduction of H2S and CO2 concentrations in sweet gas, underlining the importance of solvent selection in the acid gas removal process.
