Heavy hydrocarbon liquids derived from “bottom-of-the-barrel” (BoB) products like marine fuel or bitumen (asphalt) are a big part of the growing safety and environmental concerns about H2S in the petroleum industry.
Avoid health hazards, violations of local occupational health, safety regulations and public complaints from unacceptable high H2S levels with Clariant’s H2S scavengers. Our extensive application and chemical expertise combined with our technical services help you manage your unique H2S challenges.
Comply with the new international standard ISO 8217, effective July 1, 2012
Clariant’s SCAVTREAT® helps you comply with strict limit of 2 ppm H2S in the liquid phase of marine fuels dictated by ISO 8217. Meeting such low concentrations of hydrogen sulfide in the hydrocarbon liquid phase often can be adjusted only by using suitable H2S Scavengers.
SCAVTREAT for heavy fuel oil
SCAVTREAT H2S scavengers are specifically designed for high performance in the challenging environment of heavy fuel oil applications.
High Temperatures – SCAVTREAT performs at very high temperatures to provide injection point flexibility for the refinery.
Rapid Reaction – SCAVTREAT reacts rapidly to allow effective injection into the system with shorter residence times.
H2S Selective, Non-reversible Reaction – Lower treatment ratios of 1:5 to 1:10 per ppm H2S required by SCAVTREAT deliver a highly cost-effective solution.
Effective in a Wide Range of Fuels – SCAVTREAT provides blending flexibility for fewer product rejections and shipping delays as well as reducing odor, corrosion and safety challenges.
Oil Soluble Reaction Products – SCAVTREAT requires no expensive waste disposal.
SCAVTREAT for Bitumen (Asphalt)
Metal-based H2S scavenger products performs effectively at high temperatures. They are specifically designed to meet the requirements of bitumen producers without having a detrimental impact on bitumen properties.
Oil soluble scavengers use a special hydrocarbon solvent system to provide good solubility in bitumen with high treatment efficiency even at high temperatures for a good cost to performance ratio.
The ability of SCAVTREAT scavenger and reaction products to remain stable at very high temperatures helps prevent H2S from being released during storage or shipment.
Cutting edge nanotechnology allows fast reaction due to high reaction surface in systems with short residence times. This allows refineries to respond quickly when optimizing their scavenger treatment program at competitive treat costs.
Good handling properties make it easy to apply in bitumen production plants using standard injection equipment.
