Scavengers

Effective hydrogen sulfide management

Hydrogen sulfide (H₂S) is a naturally occurring gas contained in many of the world’s crude oils. The gas can also be formed during the refining process, as the sulfur-containing compounds are degraded at high temperatures.

Colorless, toxic and corrosive, H₂S gas presents significant safety, environmental, operational and compliance issues for refiners.

Featuring robust, proven technology, Innospec’s SulfurPurge™ range of H₂S scavengers effectively reduce and control the H₂S levels in all liquid hydrocarbon fuels, from middle distillates to residual fuel oils.

The SulfurPurge™ range allows refiners to efficiently improve fuel safety and quality, and reliably meet specification requirements.

Innospec offers two main H₂S scavenger technologies in its SulfurPurge™ range:

SulfurPurge – water soluble scavengers

SulfurPurge HC – oil soluble scavengers

Both technologies provide a rapid, non-reversible reaction when injected into the fuel run-down line or treated into the storage tank with mixing.

Based on CHNO chemistry, the halogen and sulfur-free SulfurPurge range is completely non-harmful to fuel quality. The water-based solutions are non-flammable and provide good low temperature handling properties.

The typical treat rates of the SulfurPurge range depend on a variety of factors, including the amount of H₂S to be removed, operating conditions and efficiency of the injection system. Our expert team provides tailored solutions to meet our customers’ specific requirements.

Our range includes:

SulfurPurge is a H₂S scavenger which reacts with H₂S to form a water soluble reaction product. This product can be removed from fuel by water washing or settling – reducing sulfur content and permanently removing H₂S from the fuel.

SulfurPurge reacts immediately upon contact with H₂S and provides a rapid, non-reversible reaction, ensuring the gas cannot be rereleased into fuel.

The treat rate of SulfurPurge is typically 10 to 15 times H₂S concentration in the liquid phase.

SulfurPurge HC

SulfurPurge HC is an oil soluble H₂S scavenger which produces a water soluble reaction product. The additive requires minimal mixing and is ideal for treating storage tanks and ships.

SulfurPurge HC reacts immediately upon contact with H₂S and provides a rapid, non-reversible reaction, ensuring the gas cannot be rereleased into fuel.

The treat rate of SulfurPurge HC is typically 10 times H₂S concentration in the liquid phase.
