INFLUENCE OF DEPRESSANT ADDITIVES ON CRUDE OIL FUEL

This study investigates the optimization of low-temperature diesel fuel properties through the utilization of depressant additives. Two depressant additives, K-ES and D-315, are assessed for their efficacy in improving Cold Filter Plugging Point (CFPP) and Pour Point (PP) of diesel fuels sourced from different manufacturers. Methodologically, optimal additive dosages and introduction temperatures are determined through comprehensive testing of fuel samples. Results reveal distinct behaviors of the additives, with both K-ES and D-315 exhibiting concentration-dependent effects on low-temperature properties. Notably, D-315 demonstrates superior performance at higher concentrations, significantly reducing freezing and filtration temperatures. Molecular composition and solvent characteristics are identified as critical factors influencing additive effectiveness. Overall, this study provides valuable insights into the selection and application of depressant additives, essential for ensuring efficient engine operation in challenging environmental conditions.
