Kerosiinijääkidest

Kerosiinijääkidest, commonly referred to as kerosene residues, are the byproducts left after the fractional distillation of crude oil. These residues are heavier and less volatile than kerosene itself, possessing a higher boiling point range. The composition of kerosene residues can vary depending on the crude oil source and the distillation process employed, but they typically contain a complex mixture of hydrocarbons, including paraffins, naphthenes, and aromatics, as well as sulfur and nitrogen compounds.

In terms of applications, kerosene residues are primarily used as feedstock for further refining processes. They can be subjected to cracking or visbreaking to produce lighter, more valuable products such as gasoline, diesel fuel, and jet fuel. Additionally, these residues can be blended into fuel oils for industrial furnaces and boilers, although their use in this capacity has declined due to environmental regulations concerning sulfur emissions. They also find limited use in the production of asphalt and certain specialized chemicals. The handling and disposal of kerosene residues require careful consideration due to their potential environmental impact.
