Abstract
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.关键词
