Sargent & Lundy’s overall work scope encompassed the detailed design of the structural steel and balance-of-plant (BOP) for the SCR retrofit. This included procurement of the SCR reactors and SCR ductwork. We were also responsible for all BOP design and procurement of all BOP equipment, including flue gas system modifications, ammonia supply, piles, concrete foundations, structural steel, electrical equipment, mechanical piping, etc.
