EIPL successfully implemented an Enhanced Reactive Thermal Oxidation system to eliminate hydrogen sulfide (H₂S) emissions, achieving a reduction of 2000 tons per year.
EIPL is proud to have delivered a major environmental control project for one of the world’s leading oil & gas companies, ranked among the top corporations globally.
The project focused on the elimination of hydrogen sulfide (H₂S) emissions through an Enhanced Reactive Thermal Oxidation system, designed to safely and efficiently treat large volumes of hazardous waste gases.
With a processing capacity of 400,000 kg/day, the system ensures reliable destruction of toxic components while maintaining compliance with stringent environmental norms.
The process configuration includes a high-performance heat exchanger, followed by quenching, scrubbing, and final discharge through a stack, ensuring complete treatment of flue gases.
This installation represents a significant step toward reducing environmental impact and improving air quality, while supporting sustainable industrial operations.
