This paper introduces the applications of tower plates with inclined holes in the fractional distillation project of。refractionating equipment in Yanshan 450，000 t/a ethylene extension project, and expounds the technical essentials for manufacturing and installing this kind of plates. It is proved by practices that，to reconstruct towers using plates with inclined holes under a certain working condition is characterized by the advantages of small amount of engineerings and low cost. Also after reconstruction, the plate efficiency and production capacity will be obviously increased which is superior to other kinds of plate-type towers and feeding towers.1996,3(3): 19-24 收稿日期：1996-1-8分类号：TG156参考文献：
