Economic Evaluation Of Coal Preparation In Appalachian Region Using Deterministic And Probabilistic Analysis - ABSTRACT PAGE

An economic analysis for evaluating coal preparation in Appalachian Region is presented. A complete coal preparation plant is used to deter- mine the capital and operating costs. Using profit maximization as a decision criterion, an optimal process flowsheet for given coal characteristics can be selected among the process alternatives by a process-economic model. A deterministic analysis is used to calculate the discounted cash flow interest rate of return and project the selling prices of clean coal products. A probabilistic evaluation is further made to quantify the risk involved in obtaining the desired profit levels.
