"The objective of this study was to develop relationships between capital and operation/maintenance (O&M) costs for hazardous waste incineration and the various waste-specific, design- specific, and operational factors that affect these costs. These cost relationships have been designed so that total capital investment, annual O&M cost. and unit (dollars per Ib, etc.) disposal cost estimates can be calculated for a variety of waste compositions, different incineration system designs and configurations, and a wide range of system operating conditions and performance requirements. Sequential elements of the estimation procedure are: (1) input data specifications, (2) design assumptions and engineering calculations, (3) capital cost estimation, (4) annual O&M cost estimation, and (5) unit disposal cost calculation. The input data specifications include physical/chemical waste characteristics and throughput rates, generic incinerator design type, capacity, and operating temperature, particulate and acid gas removal requirements, energy recovery utilization, and operating schedule. When these data are specified by the user, conceptual design, material balance, energy balance, capital cost, and O&M cost calculations are performed in sequential fashion. The projected accuracy of this cost estimation procedure is «30 to 40 percent." |
