Selective Non-Catalytic Reduction (SNCR) System
Demonstrating our steadfast commitment to environmental responsibility and improving air quality, QAFAC proactively invested in and commissioned a state-of-the-art Selective Non-Catalytic Reduction (SNCR) system in 2019. Specifically designed to treat emissions from our reformer, this advanced system targets Nitrogen Oxides (NOx) – harmful air pollutants known for their contribution to smog and acid rain. Through a carefully controlled process of injecting an ammonia solution into the reformer’s high-temperature flue gas, the SNCR system effectively converts NOx into harmless nitrogen and water vapor. This significant technological upgrade has allowed us to effectively reduce NOx levels while adhering to and often exceeding strict national and international emission limits. The successful implementation and continuous operation of this system have resulted in a sustained 50% reduction in NOx emissions from this source, marking a significant achievement that clearly showcases our dedication to minimizing our atmospheric footprint and contributing to cleaner air for our community and the wider environment.
Regenerant Gas Scrubber (RGS)
As part of our efforts to create positive environmental impacts through better energy management, we successfully installed a Regenerant Gas Scrubber (RGS) unit in 2021
Reduced Natural Gas Consumption
The unit continued the recycling of MTBE regenerant gas. This reduces natural gas consumption by 4.2 metric tonnes per hour
Lower Flaring Activity
The operation of the RGS unit led to a ~45% reduction in the flaring of off-spec gases
Emission Control & Monitoring
We continue to monitor data and incorporate effective management techniques for flaring off-spec gases
Cleaner Operations, Greener Future
A vital contribution to QAFAC’s goal of reducing its carbon and environmental footprint.
Ultra Low Nox Burner
QAFAC proactively addressed environmental regulations by implementing measures to reduce NOx emissions from its utility boilers. To achieve this, QAFAC collaborated with engineering consultants and technology providers to do install and commission of following units
- 4 ultra-low NOx burners (2 per boiler)
- 2 main fuel gas skids and 4 individual fuel gas skids
- Wobbe Index Analyzer for online fuel gas monitoring
- New baffles in the wind box of both boilers
- Logic changes in the burner management system (BMS) and boiler master control (BMC)
As a result of these efforts, both boilers kept operating on a mixed fuel gas (natural gas and gas from the MTBE plant) and consistently achieve significant reduction in NOx emissions demonstrates QAFAC’s commitment to environmental sustainability and compliance with regulatory standards
Fugitive Emissions
Beyond its commitment to reducing greenhouse gas (GHG) emissions, QAFAC has taken perceptive steps to safeguard air quality and human health by preventing the release of harmful volatile organic compounds (VOCs) and hazardous air pollutants. This is achieved through a rigorous Leak Detection and Repair (LDAR) program, implemented in accordance with US EPA Method 21 and QatarEnergy standards. Methane emissions, a potent greenhouse gas, are also closely monitored within the LDAR program, underscoring their significance
