Abstract: Based on a 0.5 MMTPY moving bed light hydrocarbon aromatization unit, this paper explores the basic points and precautions of the development and application of pipeline engineering for the reaction part from aspects such as the layout of the reaction framework plane, the layout of main equipment, the design of the reaction oil line, and the design of the catalyst pipeline. The application results show that the design of the reaction framework meets the requirements of process flow, safe production, pipeline layout, and operation and maintenance; the material selection of the reaction oil line meets the requirements of high-temperature hydrogen environment, and the pipeline stress analysis fully considers various working conditions such as normal operation, start-up furnace drying, and start-up system drying of the pipeline system. The pipeline layout meets the process requirements for the temperature drop and pressure drop of the pipeline system within specified values, and the reaction oil line can operate safely and stably under harsh conditions for a long term; the design of the catalyst pipeline meets the requirement of low wear rate of catalysts. The research and practice of pipeline engineering for the reaction system have achieved the expected results.
