Uitgasolie

Uitgasolie (Dutch for 'off-gas oil') is a term used in some industrial contexts to describe a hydrocarbon condensate recovered from off-gases produced during processes such as gasification, cracking or exhaust-gas treatment. The term is not standardized, and its exact meaning varies between facilities and countries; some sources use it to denote heavy condensates, while others refer to refinery or process-off-gas liquids that are subsequently upgraded or burned as fuel.

Most descriptions portray uitgasolie as a heavy, viscous oil with a high boiling range, often containing sulfur compounds, polycyclic aromatics and other impurities. Because of its composition, it is generally not suitable as a consumer lubricating oil or a direct fuel for engines without further processing.

Production and use: Uitgasolie is typically collected from gas-cleaning sections or condensers downstream of gasification, upgrading units or flare systems. Depending on quality, it may be used as a fuel for boilers and cement kilns after treatment, or it may be processed further through distillation, hydrotreating or cracking to make lighter products or chemical feedstocks.

Environmental and safety: It is usually flammable and may pose health hazards due to volatile organics and sulfur compounds. Handling requires appropriate containment, ventilation and spill controls, and waste streams must comply with local regulations for hazardous oil or off-gas condensates.
