ENERGY CONSUMPTION BASED ANALYSIS ON PRESSURE SELECTION OF AMMONIA SYNTHESIS
Based on traditional thermal catalytic ammonia synthetic process,and in respond to the different hydrogen preparation routes,this article discussed the energy consumption under different synthetic pressures.During the engineering design,suitable synthetic pressure was selected to control the ammonia synthetic energy consumption to the lowest level,helping to reduce the carbon emission.By simulating the process,studying the relationship of the fresh air inlet pressure and the synthetic pressure with the power consumption of the compressor,the circulation,and the total power consumption,we found that when the inlet fresh air pressure remained constantly,the higher the synthetic pressure was,the total energy consumption of the synthetic loop wend down first,and then rose up along with the rise of synthetic pressure,and went to the minimum in a certain pressure range.Considering the relationship between the total energy consumption of the synthetic loop and the synthetic pressure,it's suggested that different fresh air inlet pressure match with different ammonia synthetic pressure.
