The development of the additives for reduction of pour point, cold filter plugging point and providing of higher sedimentation stability of diesel and light heating fuels
Our company cooperate with the research institute to develop the additives for reduction of pour point and cold filter plugging point.
The additive concentration is selected depending on the fuel quality and composition from the customer’s perspective.
| Appearance | Viscous liquid from light grey to light brown color |
|---|---|
| Kinematic viscosity of the additive at 50 °C, mm2/sec, max | 120 |
| Pour point of the additive, °C, max | 10 |
| Flash point of the additive, °C, min | 30 |
| Pour point depression of diesel fuel of the "L" brand with 0,05 % wt. of the additive, °C, min | 10 |
| Cold filter plugging point depression of diesel fuel of the "L" brand with 0,05 % wt. of the additive, °C, min | 12 |
| Pour point depression of heating fuel containing 0,1 % wt. of the additive, °C, min | 13 |
| Pour point depression of marine fuel containing 0,1 % wt. of the additive, °C, min | 15 |
Experimental results on the use of the additive in different middle distillates
| Fuel | Concentration of the depressant-dispersion additive, % wt. | Тpp,°C | CFPP,°C | Depression Тpp,°C | Depression ТCFPP,°C |

Тpp – pour point
ТCFPP – cold filter plugging point
