A Standardized Procedure for Estimating Costs of Saline Water Conversion.

摘要

This report presents a standardized procedure for making initial cost estimates for demineralization of saline waters by various processes. Any given estimate will not necessarily represent the cost of a process at a specific location but will represent the order of magnitude for the water cost under the assumed conditions and permit valid comparison of various processes. Cost estimates are first approximations based on selected costs for investment,fuel and power,with approximations for labor,supervision,maintenance,and other items. The standardized cost estimating procedure is presented in three parts, (1) a summary of the items in tabular form for estimating the costs, (2) a discussion of the many factors contributing to the cost estimating procedure,and (3) an appendix which includes cost estimates for various items of equipment,and analyses of saline waters.
