Baker Hughes SULFIX™ H2S scavengers and services reduce the level of hydrogen sulfide gas in crude oil, intermediates, and refined products. Use of these scavengers ensures safer operations with reduced environmental, regulatory, and operational concerns at refineries, storage tank facilities, terminals, and in transport vessels.
We have the industry’s most extensive H2S scavenger product line and the most application experience. Our technology and expertise enable you to meet every sulfur management need from LPG to asphalt or any product in between.
One refinery had extreme fuel H2S levels from the vacuum tower. After an extensive evaluation, we suggested lowering the outlet temperature by 15 deg. F [ 9 deg. C] to increase hydrogen sulfide safety at the plant. That process change reduced H2S levels by more than 8,500 ppm, saving significant additive cost.
H2S in asphalt
Many customers have alerted us about high levels of H2S in their finished asphalt product which can create a health hazard for workers loading the asphalt into transportation equipment. In some situations, environmental and odor concerns have made H2S treatment a mandatory procedure for asphalt operations. As heavier crude oils are processed, we anticipate H2S problems to grow. SULFIX H2S scavengers help to increase worker safety and confirm compliance with global environmental regulations by reducing dangerous levels of hydrogen sulfide in asphalt.
Hydrogen sulfide is also a concern in fuel terminals where chemical binders, such as polyphosphoric acid (PPA), are added to enhance the value of the asphalt product. This PPA modification can trigger the regeneration of H2S, and elevate HSE risk. A Baker Hughes SULFIX™ PPA-resistant H2S scavenger program can help mitigate this concern and help control H2S regeneration during the asphalt production and blending process.
