FACTORS AFFECTING GAS OILS RESPONSE TOWARDS LOW-TEMPERATURE ADDITIVES

Gas oil samples with different physico-chemical characteristics have s hown variable response towards low temperature additives. Statistical interpretation of results indicated that magnitude in pour point and c old filter plugging point (CFPP) depression is greatly affected by the gas oil distillation range variables final boiling point (FBP) and di fference between temperature to recover 90 vol % from temperature to r ecover 20 vol %. Per cent weight of n-paraffins with carbon number ran ge C-20-C-32 is also found with great impact on that response magnitud e. The statistical models derived have supported the high degree of co rrelation between these gas oil variables towards low temperature addi tives.
