Economic Evaluation of Metal Oxide Processes for SO2Removal from Power Plant Flue Gases. Phase 3. Cost Sensitivity Study of Major Process Parameters

摘要

A cost sensitivity study has been made in which the effects of major process parameters on plant investment and operating costs have been determined. A tabulation of the parameters studies is included. Results are reported as changes from the base case values which were obtained from the previously completed phases 1and 2evaluations. Three battery limits base case process designs were developed in phases 1and 2 (dispersed phase,fluid bed,fixed bed),but not all of the variables were evaluated in phase 3for three designs. A copy of the flow sheet,process description,battery limit investment and operating cost for each of the base case designs is included for reference. A brief summary of the results on economics of the major process variables studied is shown. As a reference case,the base case investment and operating costs are also shown. (Author)
