The Build Of Chinese Natural Gas Industry Strategic Reservation System And Construction Of LNG Relay Stations

The rapid developing of Chinese economy results in increasing need for energy,but on the other hand the energy, especially oil, will put great pressure on environmentand energy safety when consumed. So it's necessary for China to change energystructure and raise natural gas's ratio in primary energy. But the generalization ofnatural gas is severely hindered by infrastructure construction problems. China'snatural gas industry started later than some other countries and the natural gas pipesstructure is weak and lack of strategic reservation construction compared withdeveloped countries, the developing schedule is lagging behind and no overallstrategic plan available.This paper analyzes the severe defects existing in china's natural gas strategicreservation system via comparing natural gas infrastructure constructions of bothhome and abroad. As to the technological characteristics and existing problems, thispaper puts forward solutions by analyzing the basic reasons for the lagging behind ofnatural gas strategic reserve system construction. And we put forward a technologicalpolicy firstly mentioned in China about attracting local people and companies to takepart in the natural gas strategic reservation system by constructing LNG relay stations.The LNG relay station is a LNG reserving equipments-cored comprehensive facilitycovering LNG reservation, transportation, usage and other natural gas industry chains.It aims at perfecting China's natural gas strategic reservation. By making full use ofLNG's physicochemical properties and cooling and heating energy, and combiningcontinuous promotion of LNG industry, we can make overall profit. In this way, weare able to attract local people and companies to take part in LNG relay stationsconstruction and perfect the natural gas strategic reservation system finally.This paper is about research on LNG relay stations'construction plan, LNG relaystations'comprehensive operation module, LNG relay stations'promoting effects tonatural gas industry, the LNG relay stations'economic evaluation model, and take aLNG satellite station(Zhejiang province)as an example for economic empiricalanalysis and assessment.Main research achievements of this paper include:1. Reasons for the lagging behind of China's natural gas strategic reservationsystem construction and propose the local capital of the southern area to take part inthe system construction.2. Putting forward the concept of LNG relay stations, and analyzing theimportance of LNG relay stations to China's natural gas industry development andenhancement of strategic energy safety.3. Analysis on the address requirements, scale deciding factors and design craftsof LNG relay stations.4. The build of economic evaluation model for the operation and investment of LNG relay stations.5. Evaluation on LNG relay stations'profitability by on-site investigation andresearch and economic data analysis on a LNG cogeneration project in Yangtze riverdelta area.
