Lining materials for wet limestone absorber modules

A large number of carbon steel, wet limestone absorber modules originally lined with rubber are now requiring replacement of the lining material. Alternatives for lining absorber modules include: metal wallpaper (high nickel alloy or 6 Mo stainless steel), rubber (natural or chlorobutyl), and glass-reinforced polymers (epoxy, polyester, and vinyl ester). This paper describes the selection process of a replacement lining for the absorber modules at a typical Midwestern power station. For each alternative, a life-cycle cost analysis was conducted, which considered initial capital, operating and maintenance, and replacement costs over the remaining life of the absorber module. The glass-reinforced vinyl ester system and metal wallpaper were predicted to have nearly identical life-cycle costs. However, the flake glass vinyl ester system has a significantly lower initial installed cost and was thus recommended on the basis of life-cycle and initial cost. Actual construction experience is presented, which confirms the recommendation to replace the lining with a flake glass novalac vinyl ester system.
