A recent trend in the gypsum wallboard industry is to utilize gypsum produced by S02 scrubbers on Coal Fired Power Plants. Clean air legislation will soon make it mandatory for most of the coal fired plants in the United States to capture their sulfur emissions. One option for beneficial use of the waste material from the scrubbing process is to convert it to gypsum. Once manufactured, the gypsum can be used in cement, fertilizer or gypsum board. In early 2008, Progress Energy will produce and deliver gypsum to a BPB gypsum board facility. The BPB Board Plant will be located adjacent to Progress Energy’s (PE) Roxboro Plant in Roxboro, North Carolina. Critical elements contributing to the partnership were: · The location of the gypsum relative to BPB’s market needs. · PE’s decision to generate wallboard quality gypsum. · PE’s ability to produce large quantities of gypsum allowing the construction of a modern high speed plant. · BPB’s long-term need for gypsum supply and PE’s long-term need for a gypsum buyer. This paper reviews the pathways taken by BPB and PE to reach a long-term agreement. The flue gas desulphurization (FGD/scrubbing) process, gypsum manufacturing technologies selected, general past and future industry trends, clean air legislation drivers and other types of synthetic gypsum will be discussed. · Click here for the presentation (~4.3 MB) – MS PowerPoint format only – paper follows below.
