：氨是一種重要的化工產(chǎn)品，在國(guó)民經(jīng)濟(jì)中有重要的作用。 關(guān)鍵詞 ： 合成氨 物料衡算 熱量衡算 合成塔 II Process Design of the Section Which Synthetizes Liquid Ammonia of 300000t/a Abstract: Ammonia is an important chemical product,plays an important role in the national is very necessary to explore and design the process of synthetic ammonia,then to optimize the process and the synthesis process includes the separation of ammonia,the gas recirculation, the ammonia synthesis,the emission of inert gas and so on,and during the process,the ammonia synthesis is the most important main purpose of this design is to devise the synthesis process of ammonia to the position of raw gas that has known,we carry on the calculation of the craft system,including material balance,heat balance,the calculation and selection of the ammonia synthesis tower is the crucial equipment of the process,bining with the design data and technical status,this design chooses three adiabatic cold shock internal cooling type
