Hetron epoxy vinyl ester resin supplied by Ashland Performance Materials (Dublin, Ohio), was used to fabricate the corrosion-resistant ductwork and direct contact cooler (DCC) components of a carbon capture and sequestration (CCS) system built for American Electric Power (AEP, Columbus, Ohio). The first of its kind in the U.S., the CCS system was introduced by Alstom Power (Levallois-Perret, Cedex, France) and was recently installed and is now undergoing validation at AEP’s Mountaineer facility in New Haven, W.Va. “This is the only CCS unit, to date, using advanced resin technology for corrosion protection,” reports Ashland product manager Thom Johnson, noting that because the “CCS system creates a very aggressive environment, fiber-reinforced plastic was chosen over stainless steel to fabricate these components.”
Ershigs Inc. (Bellingham, Wash.) provided the structural design and manufactured the FRP ductwork and DCC tower vessel for the CCS unit. Steve Hettick, VP, manufacturing, for Ershigs, says, “This is an excellent example of how composites ... can be utilized for demanding power plant applications.”
