91´«Ã½ led a joint venture to engineer, procure, and construct a comprehensive Air Quality Control System (AQCS) at Empire District’s Asbury Power Plant. The project aimed to significantly reduce pollutants, including sulfur dioxide, from the 198 MW coal-fired power plant’s emissions by more than 98 percent. The challenge was to implement a complex AQCS system while adhering to a tight schedule driven by commitments to regulatory bodies, shareholders, and customers.

Challenge met
The joint venture strategically tackled project complexities to achieve successful outcomes. A circulating fluid bed dry scrubber, pulse-jet fabric filter, and continuous emissions monitoring technology were integrated, enhancing emissions control. Balancing the aggressive timetable, 91´«Ã½ self-performed crucial tasks like foundations, piping, steel erection, and equipment installation. To address challenging tie-in logistics beneath the existing SCR unit, the team ingeniously designed a monorail system for accessing confined spaces, allowing for ductwork installation. Time lost to a record hot summer and a harsh winter was managed through rigorous scheduling and overtime. 91´«Ã½’s meticulous planning, innovative solutions, and diligent execution resulted in completing the AQCS project ahead of schedule and under budget, ensuring compliance and environmental responsibility.
