摘　　要：通过对填料进行表面处理 ,对BHS型高效填料塔进行研究与应用 ,分析了应用带来的经济效益。在甲醇 -水的精馏中应用 ,投资回收期为 1 2d ;在聚乙烯醇精馏生产过程中应用 ,投资回收期为 33d ;将此塔用于回收醋酸甲酯和甲醇 ,投资回收期为 31d。因此 ,本项目在技术和经济上都是十分合理的。After surface treatment of the packings, the study and use of the Model BHS high-efficiency packed tower are described, and an analysis is made of the economic benefit brought about by its use. When used in the rectification of methanol-water, the investment recovery period is 12 d;when used in the production of polyvinyl alcohol by rectification, it is 33 d; and when this tower is used to recover methyl acetate and methanol, it is 31 d. Consequently, this project is very rational both technologically and economically.
