Review of Unconventional Natural Gas Liquefaction Processes

Liquefied natural gas (LNG) has become an important part in the energy industry on account of its high density, low carbon emission, and convenient transportation. In recent years, with discovery unconventional resources, situation world’s liquefaction plants using conventional as feedstock is changing. Unlike traditional LNG plants, processes require special considerations design manufacturing. This review summarizes analyzes characteristics differences several typical compared to processes, including coalbed methane liquefaction, synthetic LNG-FPSO, PLNG (pressurized liquefied gas). Moreover, a state-of-the-art progress optimization presented.
