Research On Energy Consumption Of Synthetic Ammonia's Workshop Section

As the second largest chemical products except ethane, the synthetic Ammonia is an essential intermediate for the fertilizer production. On one hand, the use of synthetic Ammonia reduces the ever-increasing population pressure on food supply; on the other hand, it consumes a lot of energy resources. Under the circumstances of the energy lacking and prices increasing, the energy saving of Ammonia industry has become a hot topic.How to use the energy effectively and reduce the energy wastes during the process of synthetic Ammonia production has become the focus of researchers. According to various materials of synthetic Ammonia's workshop section, the systematic and quantitative analysis and evaluation of synthetic Ammonia is very significant for the development of this industry.In this paper, a research on the relationship between operating parameters and heat variation generated by the changes of materials through the method combining the model-building and case study is carried out. Firstly, the material balance calculation and the heat variation caused by material changes are performed. Then a mathematical model of the synthetic Ammonia's workshop section is established. Finally, on the basis of model study and data collection, a case from Yulong Chemical Pant is studied.The analysis of Yulong Chemical Plant's synthetic Ammonia workshop section showed that the demand of energy variety with operating parameters. The most suitable operating parameters derived from model study: Hydrogen nitrogen ratio is 2.9,The inert gas' content is 16%,The Ammonia's is 2.4%.The most suitable operating parameters can save lot of energy, which makes the use of energy reasonable. From the point of material, this paper studies the use energy of synthetic Ammonia, which provides a new way for the study of synthetic Ammonia' energy utilization.
