节能工艺在中哈C线项目的应用
Application of Energy-Saving Technology in China-Kazakhstan Line C Project

长输天然气管道作为天然气运输的经济高效的运输方式，随着国内天然气需求的增加，天然气长输管道建设得到快速的发展。由于天然气长输管道在输送过程中要消耗大量能源，天然气管道节能问题一直是管道行业发展中需要重点解决的问题。中哈C线项目通过采取管道内涂层措施、合理优化管径和站址、线路截断阀室应用新节能工艺方案、余热锅炉利用燃气余热、合理设置出站温度、空压机采用变频电机等一系列措施，有效地节约管道能耗，不但促进各项节能技术在输气管道工程的应用，推动天然气管道节能工作的发展，而且节约了管道运行成本，提高了企业经济效益。
Long-distance natural gas pipelines are a cost-effective transportation method for natural gas transportation. With the increase in domestic natural gas demand, the construction of long-distance natural gas pipelines has been rapidly developed. Since natural gas long-distance pipelines consume a lot of energy in the transportation process, the energy-saving problem of natural gas pipelines has always been a key issue to be solved in the development of the pipeline industry. China-Kazakhstan line C has adopted internal coating measures, optimized pipe diameter and station site, applied new energy-saving skill in valve station to connect pipelines, made good use of waste heat in the waste heat boiler, set out proper station temperature and fixed conversion motor for air compressor. The application of a series of energy-saving measures helps pipelines save energy effectively which promotes the development of energy-saving work for natural gas pipelines, reduces the operating costs of pipelines and improves the economic benefits of enterprises.
