The Problem
A chemical processing facility in the Southern US generates process wastewater with high levels of hydrogen sulfide (H2S). The disposal site where this water is transported requires 0 ppm H2S in the wastewater, imposing severe financial penalties on facilities that do not comply with this requirement.
Unable to remove H2S from their wastewater with industry-standard triazine scavengers, the facility reached out to ChemTreat for help.
The Solution
After consulting ChemTreat’s experienced refining team, the facility decided to implement our H2S treatment product CT9155. This product was selected because, unlike traditional scavengers, it rapidly reacts with H2S to form a water-soluble salt that carries with the water phase. This product promotes an irreversible reaction, removing H2S*.
The Results
Prior to implementing CT9155, the facility’s wastewater contained 2,500–6,000 ppm of H2S in each shipment to the disposal facility. After applying this technology, H2S was eliminated from the wastewater, enabling the plant to dispose of it without incurring additional fees.
The amount of treatment chemical was reduced by 40% after the product switch, resulting in estimated savings of $100,000 per year.
*Product testing should always include reacidification of water samples to ensure no reemergence of H2S.
