Mercaptan Scavengers

Mercaptan scavengers are compounds added to fuel to remove or neutralize mercaptans, which are sulfur-containing compounds that produce a foul odor like rotten eggs. Mercaptans are often present in crude oil and natural gas and can also be added to fuel as a blending component to increase its octane rating.

Mercaptan scavengers work by reacting with the mercaptan molecules and converting them into non-odorous compounds that can be safely burned in the engine. Several types of mercaptan scavengers exist, including alkali metal hydroxides, amines, and thiolates.

The use of mercaptan scavengers is essential in the transportation and refining industries, where the presence of mercaptans can cause serious safety concerns and environmental issues. For example, the strong odor of mercaptans can be a health hazard to workers in the fuel transportation and refining industries.

Mercaptan scavengers are typically added to gasoline, diesel, and jet fuel during refining. The amount and type of mercaptan scavenger used depends on the specific fuel blend and the level of mercaptans present. The use of mercaptan scavengers is regulated by various international and national organizations, including the International Maritime Organization (IMO) and the United States Environmental Protection Agency (EPA).

Mercaptan scavengers play an essential role in ensuring the safety and environmental sustainability of the fuel industry by reducing the presence of foul-smelling and potentially harmful mercaptans in fuel.
