托普索S-300塔在我公司的应用

Application of Topsoe S-300 tower in Our Company

为了尽可能提高氨的单程转化率和保持催化剂装量最低,采用了托普索最具热力学效率的S-300合成塔结构,即:"三床两换热器型",换热器分别位于第一床和第二床之后。同时在这种工艺生产中压蒸汽的产生及过热都要求在合成回路中完成,同时合成塔的这种设计,氨净值高,吨氨新鲜气消耗低,而合成塔的设计不带底部换热器,这样最大可能提高了反应热的回收。

As far as possible in order to improve the conversion rate of ammonia and catalyst was the lowest, Topsoe using S-300 synthetic tower structure, most thermodynamic efficiency namely： ＂three bed two heat exchanger type＂, after the heat exchanger are respectively located in the first bed and a second bed. At the same time under this scheme and the overheating steam pressure are required to complete in the loop, and design synthesis tower without bottom heat exchanger, so that the maximum possible increase the recovery of reaction heat.
