Liquefied Natural Gas or LNG is fast gaining the interest of many people in different countries as we fight for an alternative source of energy in the fight against the fossil fuel based energy resources. Now, Liquefied Natural Gas (LNG) is natural gas (NG) that is cooled to the point that it condenses to a liquid. I've heard and read that it is among the cleanest of all fossil fuel based energy resources when compared with other fossil fuel energy sources such as coal and crude petroleum and its derivatives. The point of this thread is to gather important information about LNG from chemical engineers present and others having knowledge in this matter. From what I am reading I've gathered that Liquefaction of natural gas to LNG reduces the volume of natural gas by approximately 600 times thus making it more economical to store natural gas and to transport gas over long distances for which pipelines are not economically feasible or there are other constraints. LNG as a transportation fuel - is also the next topic in this discussion. To begin with, let us discuss some of the advantages and disadvantages of LNG and its usage.
