Atmospheric Fluidized-Bed Combustion Waste Utilization in Cement and Sulfuric Acid: Preliminary Feasibility Study

摘要

An OACD interdisciplinary project team has investigated the preliminary feasibility of using atmospheric fluidized-bed combustion (AFBC) waste in the production of portland cement and sulfuric acid. This investigation found that it is technically and economically feasible to simultaneously produce electricity, portland cement, and sulfuric acid in an environmentally clean, integrated industrial complex. This complex would include a 500-MW AFBC unit costing an estimated $450 million, a portland cement plant costing $125 million, and a sulfuric acid plant costing $53 million. This complex would produce 990,000 tons per year of portland cement and 532,000 tons per year of sulfuric acid. This complex would be fed 1.17 million tons per year of limestone and 106,000 tons per year of auxiliary elemental sulfur. The demonstration units for sulfuric acid and portland cement production that could be combined with the 160-MW AFBC unit in Paducah, Kentucky would cost $40 million. Marketing studies indicate that the portland cement and sulfuric acid produced can readily be sold into established markets. This project team recommends that laboratory, pilot plant, and economic-engineering studies continue to prepare for the demonstration of this environmentally clean, integrated industrial complex to produce electricity, portland cement, and sulfuric acid. 165 refs., 13 figs., 21 tabs.
