Assiut Power Station — Fuel Additive for Emission Reduction
Deployment of CHIMI MAG combustion catalyst at a 600 MW Egyptian power station reduced SO₂ emissions by 18% and fuel consumption by 5%.
Challenge
A 600 MW heavy fuel oil-fired power station in Upper Egypt was facing escalating pressure from the Egyptian Environmental Affairs Agency (EEAA) to reduce stack emissions. The plant's aging boilers were producing elevated levels of SO₂, particulate matter, and visible stack opacity, exceeding the limits set by Law 4/1994. Capital investment in flue gas desulfurization was not economically feasible.
Solution
CHIMI ART's technical team conducted a 90-day field trial using CHIMI MAG-30 organo-magnesium combustion catalyst, dosed at a ratio of 1:4000 into the heavy fuel oil supply line via a metering pump. Flue gas analysis was performed continuously using a certified emissions monitoring system (CEMS), with baseline data collected for 30 days prior to additive introduction.
Results
- 18% reduction in SO₂ emissions (from 2,100 to 1,720 mg/Nm³)
- 5% improvement in boiler efficiency, saving approximately 12,000 tonnes of HFO annually
- Visible stack opacity reduced below 20% Ringelmann, achieving full EEAA compliance
