Key Performance Benefits

The low temperature treatment of middle distillates can be challenging due to the varied qualities of fuel currently seen on the market. HiTEC® 4598 additive will effectively lower the Cold Filter Plugging Point (CFPP) and the pour point of treated fuels. HiTEC® 4598 cold flow improver is formulated to give optimum performance to allow you consistently and economically meet your target specification.

HiTEC® 4598 will deliver the following benefits:
  • Depressing the pour point leading to reduced blockage in pipes and storage vessels
  • Modification of wax crystals allowing improved flow through filters
  • Improved low temperature operability by lowering the CFPP of treated fuel

Recommended Dosage

HiTEC® 4598 additive is used to allow fuel manufacturers to cost effectively meet CFPP & Pour point specifications. The CFPP specification dominates the market and the CFPP level varies by geographic region. Treat-rate my vary depending on base fuel. However, the treat-rate should be in the range of 100 to 500 ppmv. For secondary treatment we would recommend a treat-rate of 500 ppmv.
