vasakütuste

Vasakütuste is a term used in Estonian to describe leftover fuel or residues from fuel processing. This can include a variety of substances, such as distillation bottoms, sludges, or other unrefined byproducts. These materials often contain a high concentration of heavy hydrocarbons and may also include impurities like sulfur, nitrogen, and metals.

The nature and composition of vasakütuste can vary significantly depending on the specific refining processes and the type of crude oil being processed. They are generally not suitable for direct use as fuels in their raw form and typically require further treatment or specialized disposal methods. In some cases, vasakütuste may be further processed to extract valuable components or blended with other materials to create specialized fuels or industrial products. However, their disposal can also pose environmental challenges due to their potentially hazardous nature. Proper handling and management are crucial to mitigate any negative environmental impacts. The term itself directly translates from Estonian as "leftover fuels" or "residue fuels."
