Optimization of framework structure and cost analysisfor a propane dehydrogenation unit

以某丙烷脱氢装置设备框架的优化实施为例,介绍各种框架结构的特点,分析设备框架的约束条件,根据不同阶段对项目特点及条件变化的认识不断加深,动态优化。框架主要考虑荷载、空间布置和设备振动的影响,将框架结构由基础设计的全钢结构调整为部分钢结构、多数混凝土结构方式,识别到反应气压缩机及干气压缩机构架成为这些框架的关键线路,在钢筋混凝土现浇方案的基础上,进一步优化为现浇立柱、预制梁及屋顶结构复合实施,工期由9个月缩短到6个月。整个结构优化实施后,工程费用由基础设计的4047万元减少到3110万元,工期目标实现,并获得框架设备减振、减小施工安全风险等积极效果。方案动态优化并付诸实施是实现工程目标的关键。

This article uses the optimization implementation of the equipment framework for a propane dehydrogenation unit as a case study.It introduces various characteristics of framework structures,analyzes the constraints of equipment frameworks,and dynamically optimizes the project as the understanding of project characteristics and conditions evolves at different stages.The framework primarily considers loads,spatial arrangement and the impact of equipment vibration.The structural adjustment evolves from an all-steel structure in the initial design to a combination of partially steel and mostly concrete structures.The reactor compressor and dry gas compressor framework is identified as the critical paths for these framework,leading to further optimization,such as a combination of cast-in-place columns,prefabricated beams,and roof structures.The project timeline is reduced from 9 months to 6 months.Following the implementation of the entire structural optimization,the project cost decreases from the initial design estimate of 40.47 million yuan to 31.10 million yuan.Achieve the project timeline goals and achieve positive effects such as reducing vibration of framework equipment and reducing construction safety risks.Dynamic optimization and implementation of the proposed solution prove to be crucial for achieving project objectives.
