目的 在全球能源低碳转型加速的背景下,针对天然气净化厂(以下简称净化厂)普遍存在的能耗高、余能资源利用率低等问题,旨在系统分析其余能资源分布与利用潜力,探讨技术路径与发展策略,为行业能效提升与碳减排提供参考.方法 系统分析净化厂典型工艺流程与余能资源分布特征,结合热力学计算评估余能潜力;以中国石油西南油气田公司(以下简称西南油气田)为例,梳理余能利用技术及应用现状,分析面临的技术、经济与政策挑战,并提出针对性发展建议.结果 ① 西南油气田净化厂余能资源丰富,总量约58.5 MW,预计年发电量2.5×108 kW·h;② 已在净化厂、输配气站、储气库、燃气终端等不同生产场站成功应用透平式、螺杆式、双转子式 3类主流膨胀发电技术,展现出较好的工程适应性;③ 当前面临机组稳定性不足、工况适应性差、技术成熟度低及配套政策有限等挑战.结论 净化厂余能回收利用是提升能源综合利用率、降低碳排放的重要途径.建议从技术创新与装备升级、政策支持、多能互补协同、信息化与智能化 4个方面协同发力,实现经济与环保双赢.
Objective Against the backdrop of accelerating global energy decarbonization,this study aims to systematically analyze the distribution and utilization potential of waste energy resources in natural gas purification plants(hereinafter referred to as"purification plants"),which commonly face high energy consumption and low recovery efficiency.The paper explores technical pathways and development strategies to provide reference for improving industry energy efficiency and reducing carbon emissions.Method A systematic analysis is conducted on typical process flows and waste energy resource distributions in purification plants,combined with thermodynamic calculations to assess waste energy potential.Taking PetroChina Southwest Oil&Gas Field Company(hereinafter referred to as"Southwest Oil&Gas Field")as a case study,the paper reviews current waste energy utilization technologies and their application status,analyzes existing technical,economic,and policy challenges,and proposes targeted development recommendations.Result First,waste energy resources in Southwest Oil&Gas Field's purification plants are abundant,with a total capacity of approximately 58.5 MW and an estimated annual power generation of 2.5×108 kW·h;Second,the field has successfully applied three mainstream expansion power generation technologies—turbine,screw,and dual-rotor systems—across various facilities including purification plants,transmission and distribution stations,storage reservoirs,and gas terminals,demonstrating strong engineering adaptability;Third,current challenges include insufficient unit stability,poor operational adaptability,low technology maturity,and limited supporting policies.Conclusion Waste energy recovery in purification plants represents a crucial pathway for enhancing overall energy utilization and reducing carbon emissions.It is recommended to promote coordinated efforts across four dimensions—technological innovation and equipment upgrades,policy support,multi-energy complementarity and integration,and digitalization and intelligent management—to achieve a win-win outcome for both economic growth and environmental protection.
