指出在天然气供气领域中,调峰LNG工厂在匹配峰荷和增加供气可靠性方面正起着重要的保证作用,设计调峰LNG工厂,需考虑一系列非液化流程问题,如原料气处理、压缩机及其驱动系统,以及与管网的连接等.调峰厂的经济性是由多种因素决定的,而正确选用液化流程是最重要的一步,简介了基本液化流程,举例对各种基本流程的投资成本、水电气需要量、比功耗、运行要求(包括启动与停机、人员配备、操作难度、运行成本)及灵活性等进行了全面对比。最后指出了非比较基础条件下的流程选择应注意的问题.
It is pointed out that in the field of natural gas supply, the peak-shaving LNG plant plays an important role in ensuring the peak load and increasing the gas supply reliability. To design a peak-shaving LNG plant, a series of non-liquefaction process problems need to be considered, such as feed gas treatment , Compressor and its drive system, connection with pipe network, etc. The economy of peak shaving plant is determined by many factors, and the correct selection of liquefaction process is the most important step. The basic liquefaction process is introduced, The basic process of investment costs, water and electricity demand, than the power consumption, operating requirements (including start-up and shut down, staffing, operational difficulties, operating costs) and flexibility to conduct a comprehensive comparison. Finally, it points out the problems to be noticed in the process selection under the non-comparative basic conditions.
