摘要
对溶液结晶法制五水偏硅酸钠作了技术经济评价，认为该工艺条件简单，反应条件温和，操作方便，投资少，经济效益明显，适合于中小型企业和乡镇企业投资建厂。
The techno-economic evaluation on the production of aqueous sodium metasilicate by aqueous solution crystalgrowing method has been made in this paper. It is indicated that the process has some advantages,e,g. simple technological conditions , moderate reaction conditions, convenient operation , lower capital cost,obvious economic profit etc.Therefore,the process is suitable for the plant in medi um and small scale enterprises.
