Optimization of lng cold energy utilization via power generation, refrigeration, and air separation

Natural gas is conventionally transported in its liquid form or Liquid Natural Gas (LNG). It is then transported using cryo-genic insulated LNG tankers. At receiving terminals, LNG is regasified prior to distributing it through gas distribution sys-tem. Seawater has been used as the heat source, whi...
