Mercer SCR (Selective Catalytic Reduction)

Objective: Engineering, Construction and Start-up of State-Of-The-Art Back End Technology

 

Project Summary

The Mercer SCR Project involved the addition of Selective Catalytic Reduction (SCR) Units to Mercer Generating Station Units 1 and 2. Merrimac provided project management and project engineering support including scheduling. Merrimac also performed systems and controls engineering, construction support and start-up services.

 

Specific systems that Merrimac worked on included Ammonia storage and forwarding, Ammonia vaporization and injection, gas to gas heater, soot blowing, static mixing, DCS programming and electrical distribution.

 

In addition to the above referenced efforts, Merrimac developed O&M manuals and conducted operations and maintenance training.
