"The research on the optimization technology of the driving process of large-scale ammonia plant" is the 1999 scientific and technological project of Xiangyang City undertaken by Henan Zhongyuan Dahua Group Co., Ltd.
The large-scale ammonia plant researched by the scientific and technological research project "Study on the optimization technology of the driving process of large-scale ammonia plant" is an AMV energy-saving device introduced from Germany. Due to equipment, instruments and Other reasons, there will inevitably be more than 10 parking every year. According to the technical documents provided by foreign companies, it takes 24 hours to drive. A large amount of water, electricity and natural gas are wasted during the driving period, causing huge economic losses.
According to the actual situation of the device, the project team conducted an extensive and extensive investigation of the possibility of optimization of the driving process. According to the analysis and research of several key stages in the driving process, on the basis of this, a perfect technical plan was developed to find out the technical key to solve the problem of reducing driving time. 1 Design instrument interlocking software to make the system urgent After parking, ensure the operation of the auxiliary boiler; 2 find out the optimal speed and time of chemical feeding, change the method of feeding at a fixed speed time in the past; 3 select the optimal heating time of the low-variet furnace, and increase the temperature of the low-temperature furnace The temperature rise of the second stage furnace is carried out simultaneously; 4 the heating furnace is not started, so that the synthesis tower catalyst is heated and balanced by heat.
After the implementation of the research on the ammonia plant of Henan Zhongyuan Dahua Group Co., Ltd., the driving time of the ammonia plant was reduced from 24 hours to 15 hours, and the requirements of the science and technology project contract were met. After the operation assessment, the data comparison shows that the technical indicators of the research have reached or exceeded the same type of domestic equipment.
