Environmental Impact Mitigation Through Innovational Waste Gas Incineration

Abstract This paper evaluates an incinerator system that integrates advanced waste gas incineration with renewable energy aiming to optimize waste management reduce emissions. The study explores this technology's capacity to address the specific needs of the petroleum industry, including handling hazardous waste and improving sustainability in regions like the UAE & KSA. The development involved a comprehensive approach combining computational modelling (CFD), prototype testing, and field trials, utilizing CFD simulations for combustion process refinement. A prototype was deployed for the first time in the region in Abu Dhabi field, in close proximity to a populated area, where elimination of visual flare, emissions and odours was required, while incorporating solar energy for ignition. Performance metrics such as emission levels, energy efficiency, and adaptability to diverse waste streams were rigorously tested to ensure compliance with stringent environmental and industry standards. A life cycle assessment (LCA) was also conducted to evaluate the system’s holistic environmental impact. The hybrid incinerator demonstrated remarkable results, achieving over 99.9% total hydrocarbon (including Volatile Organic Compounds (VOCs) and BTEX compounds) destruction efficiency, effectively eliminating free carbon particles and significantly reducing CO emissions to below 10 ppm. The system proved capable of safely handling diverse hazardous gas streams, including H2S. Economically, it offers a high return on investment (ROI) due to notably lower construction costs compared to conventional enclosed flare systems that can achieve the same results. These findings suggest the incinerator can significantly reduce the petroleum industry's environmental footprint, promote energy recovery, and align with circular economic principles. The system meets and exceeds regulations from the United States Environmental Protection Agency (EPA), Alberta Energy Regulator (AER), Saskatchewan MOE regulations, and aligns with the UAE Net Zero by 2050 objectives. And while the use of energy recovery is from generated heat and converting it into usable energy is achieved in other industries, we hope that one day we can incorporate these technologies in the oil and gas industry.
