PACHEM-D-CFI
Cold Flow Improver for Middle Distillates
General information:
PACHEM-D-CFI is a polymer composition in higher boiling hydrocarbons. Pachem-D-CFI is intended for improving the cold flow properties of middle distillates. Both the CFPP and Pour Point of diesel and light heating oils can be considerably reduced*.
Typical Physical And Chemical Properties:
| Parameter | Unit | Value | Test method |
|---|---|---|---|
| Appearance at 20 0C | - | milky to pale yellow viscous liquid | PB-01 - edition 1 |
| Density at 15 0C | kg/m3 | 880-940 | PN-EN ISO 12185:2002 |
| Pour Point | 0C | > 0 | PN-ISO 3016:2005 |
| Flash point | 0C | > 62 | PN-EN ISO 2719:2007 |
| Viscosity at 40 0C | mm2/s | 50-80 | PN-EN ISO 3104:2004 |
Application:
Pachem-D-CFI is suitable for both summer and winter oils. It is particular intended for middle distillates having a narrow boiling range characterized by a (90-20)%- at value of 70-100 °C and a (FBP-90%)- at of 17-25 °C. The product also is showing good performance in wider range distillates where the (90-20)%- at value is 100-120 °C and the FBP is below 380 °C (ASTM D 86 distillation).
Treat Rate:
According to the characteristics of the particular middle distillate 300-500 ppm is usually sufficient to achieve the desired CFPP and/or Pour Point response. Higher dosages up to 1000 ppm may also be used while observing the recommended blending conditions. The dosage rates required are very dependent on the characteristics of the middle distillate to be treated.
Pachem-D-CFI can be dosed undiluted at gas oil temperatures down to 30 °C depending on the characteristics of the gas oil in which it is doped in. At lower temperatures a dilution with naphtha or kerosene (ratio 1:1 to 1:3) is recommended. The middle distillate should be at least 10 °C above its cloud point at the time of additive injection.
Packaging:
Heated road tanker/tank container or 1000 l IBC.
