Computer analysis of coal preparation plant economics and equipment selection

Technical Report ·
OSTI ID:5721097
A computer program has been developed for determining the capital and operating costs for coal preparation plants. The logic of the computer program is based upon a survey of existing preparation plants, operators, plant contractors, equipment manufacturers, and consulting firms. This survey provided information on plant performance, order-of-magnitude costs, and costing procedures. Additionally, an extensive cost data file for the major capital equipment in coal preparation plans has been developed. Generalized and representative circuit flowsheets that portray real-world situations were analyzed. With this computer program, it should be possible to: (1) determine preliminary costs for most preparation plant flowsheets; (2) investigate the costs of each level of preparation; (3) study the effects that size distribution would have on costs; (4) fluctuate the specific gravity of separation to optimize both capital and operating costs; (5) compare the costs of different processes and procedures; and (6) help design the optimum flowsheet by making the above comparisons. The basic inputs to the program are: (1) size consist percentages of the raw feed; (2) yields at the designed washing specific gravity by size; and (3) unit operations in the plant to be designed. The ouptut of the program includes: (1) the size of the equipment associated with each unit operation and (2) the detailed breakdown of capital and operating costs. In addition to the development of the pogram, this study reviewed prior research and published literature related to preparation plant design, anc coal preparation plant capital and operating costs.
