摘要
结合某厂500 kt/a移动床轻烃芳构化装置,从反应构架平面布置、主要设备布置、反应转油线设计、催化剂管线设计等方面,对反应部分管系工程开发及应用的基本要点和注意事项进行了探讨。应用结果表明,反应构架的设计满足工艺流程、安全生产、管道布置、操作检修等要求;反应转油线管道选材满足高温临氢环境要求,管道应力分析充分考虑了管系的正常操作、开工烘炉、开工系统干燥等多种工况组合,管道布置满足管系温降、压力降在规定数值的工艺要求,反应转油线可在苛刻条件下长期安全稳定运行;催化剂管线设计满足催化剂低磨损率的要求。反应系统管道工程研究与实践取得预期效果。
Based on a 0.5 MM TPY 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 section from the aspects of reaction framework layout,main equipment layout,oil transfer pipe design,catalyst pipe design,etc.The application results show that the design of the reaction framework meets the requirements of process flow,safety production,pipeline layout,operation and maintenance,etc.;the selection of materials for the oil transfer pipe meets the requirements of high-temperature and hydrogen environments,and the stress analysis of the pipeline fully considers various working conditions such as normal operation of the pipeline system,start-up drying,and start-up system drying,and the pipeline layout meets the process requirements of the drop of temperature and pressure of the pipeline system within the specified value,the oil transfer pipe can operate safely and stably for a long time under harsh conditions;the catalyst pipeline design meets the requirements of low catalyst wear.The expected results have been achieved in the research and application of pipeline engineering for the reaction system.
