摘　　要：为了让氨合成生产装置能在高产、优质、低消耗的工况下运行。应用PRO/Ⅱ模拟软件,选择SRK热力学方程对高压下的氨合成回路进行模拟计算,并通过改变驰放气中惰性气体摩尔分数分析对氨合成回路的影响。得出循环气中的惰性气体摩尔分数与氨净值、循环机功耗、原料气消耗量以及氨合成塔出口温度间的变化关系,从中找出合理的惰性气体摩尔分数,用以指导氨合成的现场生产。In order to achieve high yield,better quality of ammonia product,low consumption in ammonia plant,the ammonia synthesis loop at high pressure was simulated by employing process simulation software PRO/Ⅱ and SRK thermodynamic equation.The effect of inert gas on ammonia synthesis loop was analyzed by changing the mole fraction of inert gas in relief.The relationship among between the mole fraction of inert gas and ammonia mole fraction,the shaft power of recycle compressor,fresh gas consumption,and the temperature of converter outlet stream was analyzed,from which the optimal mole fraction of inert gas was determined to direct the ammonia plant to achieve the best performance.
