| Abstract: | Power generation using LNG cold energy was a high efficiency technology. Direct expansion refrigeration, low temperature rankine cycle, combined method, low temperature brayton method and multilevel compound cycle were commonly used technology. By comparing those technologies, it concluded that low temperature rankine cycle was good at recovering LNG cooling energy and LNG cryogenic exergy and was the development trend of power generation with LNG cold energy. |
