Abstract: An optimization model for estimating the properties and cost of washed coal from coal beneficiation plants of varying levels of complexity is described. The design and technical description of the plant performance model is presented, together with cost algorithms for three plant designs with increasing sulfur removal capability. Important concepts included in the model are the treatment of different coal size fractions, the “efficiency” of coal washing equipment, and the optimization of plant yield to achieve a target coal quality. When em...
