摘 要:
LNG（液化天然气）是常温的天然气经过脱酸、脱水处理,通过冷冻工艺液化而成低温（-162℃）的液体,其密度大大增加（约600倍）,有利于长距离运输。进口LNG运抵接收站后还需要加热至常温状态才能正常使用,在这个过程中,冷能可以被回收利用。LNG冷能回收可用于空气分离、冷能发电,干冰制造、低温粉碎和蓄冷业等。这不仅有效回收、利用了能源,而且减少了机械制冷造成的大量电能消耗,具有可观的经济效益、环境效益和社会效益。[著者文摘]

Developing LNG Cold Energy Recycling Industry Actively
Ren Xianzheng, Gu Anzhong, Yuan Junfeng
Abstract:
LNG （liquefied natural gas） is a kind of normal temperature natural gas, which is deacidified and dehydrated and becomes a low temperature （-162℃）liquid through refrigerating liquidizing technology, it＇s density augments about 600 times, which could benefit long distance transporting. When the imported LNG （liquefied natural gas） arrived at the station, it still needs heating into normal temperature for further using. During this period, the cold energy could be recycled. LNG （liquefied natural gas）＇s recycled cold energy would be utilized in the following fields, such as air separating, cold energy power generation, dry ice manufacturing, low temperature comminution and cold energy storage etc. all above would recycle energy effectively, reuse cold energy and reduce large power energy consumption in mechanism refrigerating, hence this technology would embody economic effect, environmental effect and social effect.[著者文摘]
Key words:
LNG（liquefied natural gas）; cold energy recycle; energy saving; economic effect
