By-Products from Saline Water Conversion Plants. A Feasibility Study

摘要

This report summarizes a feasibility study on recovery of by-products from saline water conversion plants conducted for the Office of Saline Water, United States Department of the Interior, by the American Cyanamid Company. The objective of the survey has been to determine whether recovery of salable by-products from minerals present in saline waters offers a practical route to reducing the overall cost of converting these saline feeds to fresh water, and to delineate areas for further research and development on recovery processes. The investigation was purposely made broad to include a maximum number of the known processes and chemical reactions which could be used - either singly or in combination - to recover minerals present in economically significant amounts. The choices were narrowed by comparing the value of bulk by-products with major cost elements using the particular process, and preliminary cost estimates were made for the most promising of the remainder. Only products isolated directly from saline water were included; further upgrading was not considered in this initial study, although it would probably improve the overall economics. (Author)
