Feedstock characteristics and preparation for peat gasification. Volume I: tasks 8, 10, 11, and 12. Final report Jul 80-Jul 81
This report describes the work conducted by the Institute of Gas Technology, Dravo Corporation, and Williams Brothers Engineering Company during Phase II of the two-phase program. The objective of Phase I was to review the literature and identify needs in the areas of resources, harvesting, dewatering, beneficiation, gasification, and environmental studies. The results of Phase I have been previously reported (PB81-222275). The objectives of Phase II are to prepare updated peat resource maps and to conduct quantitative economic and environmental assessments of a few selected peat harvesting, dewatering, and beneficiation alternatives. In the task on peat resources, maps of fourteen states have been completed. A number of peat harvesting system designs have been ranked according to their technical merits and a preliminary economic assessment has been made of a wet harvesting method. A preliminary economic comparison of four peat dewatering systems has been made. A description of a beneficiation (wet-carbonization) process and a preliminary economic estimate for producing beneficiated peat is presented. Recent developments in both thermal and biological conversion of peat to SNG are described. The major air and water pollution emission rates from a peat gasification plant producing 250 billion Btu/day of SNG have been estimated. Detailed environmental scenarios have been prepared for three peat bogs typical of those in the Upper Midwest, Northeast, and Southeast United States. Preliminary cost estimates for harvested peatland reclamation options have been made.
