摘要:

系统介绍了150 kt/a单炉膛裂解炉的配管设计工作。以国内某乙烯装置裂解炉单元管道设计为例,重点围绕裂解炉区平面布置方案的确定、立式急冷换热器支撑结构与定位设计、裂解气输送系统及上升管/下降管的管道布置策略,以及炉前管廊柱距设计原则与进料管阀组布局方案等展开论述。通过对裂解炉单元关键设备选型、核心管系配置等标准化设计进行可行性论证,提出了具有工程实践价值的标准化布置方案建议。

Abstract:

This paper systematically introduces the piping design of a 150 kt/a single-chamber cracking furnace. Taking the piping design of a cracking furnace in a domestic ethylene plant as a practical case study, it focuses on the determination of planar layout scheme for the cracking furnace area, the support structure and positioning design of vertical quench heat exchangers, the piping design strategies for cracked gas conveying system and riser/downcomer, as well as the design principles for column spacing in front-furnace pipe racks and the layout schemes for feed pipe valve groups. Through feasibility verification of standardized design for critical equipment selection and core piping system configuration in the cracking furnace, this study proposes standardized layout solutions with engineering practical value.
