J.T. Deely Unit 2 SCR Retrofit Project - San Antonio, Texas
Using an innovative approach, the project team chose to reuse existing ESP steel for the J.T. Deely Unit 2 SCR Retrofit Project instead of opting for demolition. This decision reduced the project construction schedule while minimizing disruption to plant operations. The concept allowed the project team to reuse the existing foundations to start the project “out of the ground,” eliminating the potential risk of disturbing underground utilities. In addition to excellent use of available resources, the project team designed a compact selective catalytic reduction (SCR) system and top catalyst loading to meet the needs of this power facility and the surrounding community.
The team of Kiewit and PCL Industrial Construction Co. (formerly Teton Industrial Company) was awarded the contract to engineer, procure and construct an SCR system to an existing 440-megawatt coal-fired power plant. This will reduce nitrogen oxide (NOX) emissions and ammonia slip from J.T. Deely Unit 2.
San Antonio is committed to becoming an environmentally friendly city, so this SCR project will meet some of the most stringent emission requirements in the United States. These strict requirements are part of their goal to help the owner, the largest municipal power producer in the country, become one of the best electrical utilities in environmental stewardship in the United States.
