Merichem Technologies Announces Breakthrough ECOTREAT Field Trial Results: New Hydrogen Sulfide Removal Process Treating Gas from Production Separator
Merichem Technologies, a global leader in sustainable sulfur removal and treatments, today announced successful results from its ECOTREAT® field trial in the Permian Basin, demonstrating that its new hydrogen sulfide (H2S) removal process achieved sustained removal of > 99% of hydrogen sulfide gas without producing ANY solid waste products.
The new core technology uses an aqueous phase proprietary catalytic process that converts H2S into thiosulfate. By keeping the reaction entirely in solution, the process eliminates the solid waste characteristic of liquid redox or solid media systems. The approach also prevents plugging and downstream corrosion issues often encountered with triazine treatment. The only required feed reagent is potash added to feed water or produced water (which already contains the required salts). The aqueous effluent can be discharged into saltwater disposal systems or sent downhole with unneeded produced water. In simplified configurations, the system can treat H2S directly in produced water, reducing hazards associated with produced water handling.
