LNG接收站主要耗能设备能效测试分析与优化措施
Energy efficiency testing analysis and optimization measures for major energy-consuming equipment in LNG receiving terminals
摘要
Abstract
To investigate the energy utilization status of liquefied natural gas(LNG)receiving stations,taking a large domestic LNG receiving station as the research object,a method combining on-site testing and data analysis is adopted to calculate the efficiency and conduct economic evaluations of the low-pressure pumps,high-pressure pumps,BOG compressors and seawater pumps of this receiving station.Specific optimization measures are proposed in terms of equipment maintenance management,intelligent control,operation processes and equipment renovation.The results showed that the low-pressure pump and high-pressure pump units are not economically operated by 57.1%and 33.3%,respectively.The seawater pump unit is not economically operated at all.The BOG compressor operated reasonably.Through measures such as optimizing unit operation,strengthening equipment maintenance,and implementing frequency conversion renovations,annual electricity costs are saved and CO2 emissions are reduced.关键词
