Research on Optimization Operation of Steam Pipeline Network in Petrochemical Production Plant

摘要

石化生产装置在连续化、高负荷的工艺体系中对蒸汽能源的依赖度较高，蒸汽管网作为动力保障系统，其运行效率直接关系到装置能耗水平与生产稳定性。当前行业普遍面临蒸汽压力波动、输配损失偏高、负荷匹配度不足等问题，使管网的整体运行成本持续增加，并影响工艺流程的连续稳定运行。通过构建蒸汽需求特性模型、分析蒸汽管网的结构特征、识别运行瓶颈，可为优化运行策略奠定基础。本文旨在提升蒸汽输配效率、降低运行能耗、增强系统安全性，为石化生产装置能源精细化管理提供技术支撑。

Abstract

Petrochemical production units rely heavily on steam energy within continuous and high-load process systems,and the operational efficiency of steam pipe networks,as a core power-supply system,directly affects energy consumption levels and production stability. The industry is currently confronted with issues such as steam pressure fluctuations,high transmission losses,and insufficient load matching,which continuously increase overall operating costs and disrupt the stable continuity of process flows.By establishing steam demand characteristic models,analyzing the structural features of steam networks,and identifying operational bottlenecks,a solid foundation can be laid for formulating optimized operational strategies.This study aims to enhance steam transmission efficiency,reduce operating energy consumption,and strengthen system safety,thereby providing technical support for refined energy management in petrochemical production units.
