Description

Technical Field

[0002] The amination process is a common but highly hazardous chemical process. The reactants, such as liquid ammonia and ammonia gas, are mostly flammable and explosive, easily leading to combustion and explosion accidents under certain conditions. Furthermore, because ammonia is alkaline and highly corrosive, it can react chemically with copper, silver, tin, zinc, and their alloys, even in the presence of small amounts of moisture. Currently, training in the amination process often involves on-site explanations and practical demonstrations, which can easily lead to accidents due to improper operation by new employees or insufficient anticipation of hazards. Moreover, this approach makes it difficult for new employees to thoroughly understand and master the operation details of complex equipment, and they struggle to develop a clear and complete understanding of the overall process flow and the spatial relationships and logical sequence of equipment layout. This hinders their efficient and safe integration into their roles and the development of their professional skills. Summary of the Invention

[0027] like Figures 1-7 As shown, liquid ammonia from the tank area is heated and vaporized by an ammonia vaporizer and then enters an ammonia buffer tank 2. The vaporized ammonia then mixes with vaporized m-xylene entering a m-xylene vaporizer 1. The mixture then enters a mixing feed preheater 4 for preheating. After heating, it enters a fluidized bed reactor 8. Air is pressurized by a blower 6 and then heated by an air preheater. Part of the air enters the fluidized bed reactor 8 directly, while the other part is heated by an electric heater 7. Once the predetermined temperature is reached, the air enters the fluidized bed reactor 8, causing the vaporized material to react within the fluidized bed. The large amount of heat generated during the reaction exchanges heat with pure water in a steam drum 10, and the resulting steam enters the steam pipeline network. The reacted gas phase enters an oil cooler 11 from the top of the fluidized bed, where it is cooled and then enters a material collector.
