Nalco Water offers advanced non-nitrogen H₂S scavenger technology designed to effectively reduce hydrogen sulfide across a broad range of hydrocarbon streams, including crude oil, heavy fuel oils, bunker fuels, marine fuels, diesel, gasoline and other finished fuels. This innovative chemistry provides refiners, terminals, fuel marketers and transport operators with an effective H₂S mitigation solution while minimizing nitrogen contribution to downstream processing and fuel quality concerns. The technology is designed to support safe handling, transportation and storage of sulfur-containing hydrocarbons while helping customers meet product specifications and operational objectives.
Hydrogen Sulfide in Hydrocarbon Streams
Hydrogen sulfide (H₂S) is naturally present in many crude oils and can also form during refining through the decomposition of sulfur-containing compounds. H₂S can partition between liquid and vapor phases depending on temperature, agitation, pressure and product composition. Elevated H₂S levels create safety, operational, and product quality concerns throughout the hydrocarbon value chain.
Producers, refiners, terminals, marine fuel suppliers, and fuel distributors commonly monitor and control H₂S to improve worker safety, reduce handling risks, support regulatory compliance and meet customer specifications. Effective H₂S management is particularly important in crude oil, heavy fuel oils, fuel oils, bunker fuels, marine fuels and transportation fuels where there is H₂S generation or release.
H₂S Control Across Multiple Hydrocarbon Streams
Crude Oil
Sour crude oils often contain naturally occurring H₂S that can create safety concerns during transportation, storage and processing. Effective scavenging can reduce vapor-phase H₂S exposure and improve handling conditions throughout the supply chain.
Heavy Oils, Fuel Oils and Bunker Fuels
Heavy hydrocarbons, residual fuels, fuel oils, and bunker fuels typically contain higher levels of sulfur compounds that can degrade into H₂S over time or that is present in the heavy oil. These products frequently require H₂S treatment to meet transportation, storage and marine fuel specifications while helping protect personnel, assets, and cargo quality. Compliance with industry requirements and safe vessel loading operations often make H₂S control a critical component of fuel management programs.
Finished Fuels
Diesel, gasoline, marine gas oil and other refined products may contain H₂S. Controlling H₂S helps maintain product quality, support specification compliance and reduce safety concerns associated with fuel handling and transfer operations.
