Hydrated Lime Injection System

Mesa’s Power Generation group was contracted by a large electric utility company to support the installation of a Hydrated Lime Injection System (HLI) for a 924 MW coal-fired electric generating facility located in Florida.  HLI is a controlled method of mitigating SO2 and SO3 emissions by injecting powdered hydrated lime sorbent directly into a utility’s ductwork.  Key equipment arrived on site prior to the start of design which presented challenges to the project schedule, requiring our multi-discipline team to provide 10 separate design packages to avoid construction delays or hold points.  Mesa’s scope of work included a site walkdown, a laser scan with a 3D model, specifications and drawings for a pre-engineered metal building, as-built construction drawings, and all balance of plant systems.
