The Study Of Rankine Cycle Utilizing LNG Physical Exergy

As the one of the three primary energy sources for human civilization, natural gas will be the most widely used energy type, for its excellent performance: high efficiency and quality, clean. When the geography condition is not very convenient for the transportation of natural gas with pipeline, the liquefied natural gas (LNG) form must be adopted. In the project application the natural gas terminal accepts the gas form, which means LNG must be regasify before used. For the huge condition differences between LNG and the atmosphere, great amount of physical exergy will be released from LNG during its evaporation. The paper bases on this idea to study how to use the Rankine cycle to recycle this part of energy and the following work was finished:(1) The main public documentations and papers about the LNG physical exergy utilization were consulted and studied. The effect of all kinds of LNG physical exergy recycles were analyzed, including the important Rankine...
