WHY

Objective to find a low cost alternative to wet scrubber

(SO2 Control) and SCR (NOx Control) for liquid fuel fired boilers, CGTs, and

process heaters.

WHAT

Two Stage Bench scale and Pilot scale studies

Treatment of flue gas from heavy oil-fired boilers

Electron Beam Flue Gas

Treatment

HOW

Collaboration between Saudi Aramco, King Abdulaziz City for Science and Technology

and Institute of Nuclear Chemistry & Technology

STAGE 1

Saudi Aramco piloted the technology at its

Jeddah Refinery

Achieved removal efficiencies of more than 80% for Nox and

more than 95% for Sox. Byproduct was found to

comprise mostly ammonium sulfate, a fertilizer component

STAGE 2

BENEFITS

Possible Fuel-SwitchingHigh SO2 and NOx removal efficiencySO2 and NOx are reduced in one stageProcess generated no wastewateror solid wasteBy-product: A fertilizer componentCost: Less expensive that conventional alternatives

Proved the removal of Sox NOX

(efficiency rate of > 95%) and NOX

(efficiency rate of > 85%)

Byproduct: A saleable fertilizer component
