Flange reactor

The basic characteristics of the reactor reaction process determine the appropriate reactor form. For example, the gas-solid phase reaction process is generally carried out using fixed bed reactors, fluidized bed reactors, or moving bed reactors. However, the appropriate selection needs to consider various factors such as the thermal effects of the reaction, the requirements for reaction conversion and selectivity, the physical and chemical properties and deactivation of the catalyst, and even require conceptual design for different reactors and technical and economic analysis before it can be determined.

In addition to the form of the reactor, the operation and feeding methods of the reaction pot also need to be considered. For processes with series or parallel side reactions, segmented feeding may be superior to single feeding. The temperature sequence is also an important factor in reactor selection. For example, for exothermic reversible reactions, a temperature sequence from high to low should be adopted, and multi-stage and inter stage heat exchange reactors can make the temperature sequence of the reactor more reasonable. Reactors play an important role in process industry production. In terms of the overall construction investment and operating costs, the proportion of reactors may not be very large. However, its performance and operational advantages and disadvantages affect the output and quality of pre-processing and product, and also have a significant impact on raw material consumption, energy consumption, and product costs. Therefore, the research and development of reactors are of great significance for the development of various process industries.
