Gulf Chemical

Gulf Chemical is the official distributor and stockist in Singapore for Innospec’s H2S SulfurPurge™.

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.
