Peat characteristics and reserves of peat in the US, Canada, and Soviet Union are reviewed. Dry harvesting of peat typically removes 3-6 inches per year in northern climates and 12-18 inches in southern regions. A wet extraction method is described in which the full depth of peat can be mined at one time with floating equipment, thereby cutting the acreage under development and allowing reclamation to be initiated immediately after production. The peat slurry containing about 10% solids is transported via pipeline to a processing plant for dewatering. The J.P. Energy process is a wet carbonization process which thermally treats the peat under 20 atmospheres pressure at 400 F for 15-30 minutes, producing a high density, moisture resistant, dust-free fuel with a heating value over 11,000 Btu/lb. Some process heat is supplied by the anaerobic digestion of waste water from the process. A 290,000 tons/yr plant is proposed for Milford, Maine. The process description, development, and equipment, the Northern Peat Energy Project, and future applications of the peat wet carbonization technology are summarized. 7 references.
