Emissions Retrofits

With growing climate change considerations, we work with customers to develop retrofits that will have a big impact

Whether reducing emissions or extending the life of a plant, this highly complex work begins with a thorough assessment of technical and economic viability constraints and the development of innovative solutions that will result in successful project execution. We can also assist with specifications, bid evaluations, and first of a kind evaluations (e.g., Powerspan). 

Retrofits can be capital intensive, which is why engagement along with detailed studies and analysis are crucial to understanding what modifications or upgrades make the most sense. Bechtel’s technical expertise, global procurement, and project experience help improve the constructability of equipment and systems, reduce construction and overall costs, minimize changes through early site review, and mitigate disruptions to plant operations. Our end goal is to build trust and confidence among our customers and to successfully deliver a reliable, operable plant, no matter the size, scope, or complexity.

Featured project

W. H. Sammis Power Plant, Ohio, USA

This massive project included the retrofit of seven power units at the W.H. Sammis Plant in Stratton, Ohio. Bechtel handled design, procurement, installation, and startup of three sulfur dioxide scrubbers, which are the main components of a flue gas desulfurization system designed to remove more than 95 percent of the sulfur dioxide from emissions at all seven units. The project also reduced emissions of nitrogen oxide by at least 64 percent.
