Natural gas liquefaction chambers. Heat exchangers used at a liquefied natural gas plant to cool natural gas into liquid form so that it can be more easily transported for use as a fuel. Natural gas is a fossil fuel obtained from underground oil and gas deposits. These are the Main Cryogenic Heat Exchangers (MCHEs) at Sakhalin Energy's Liquefied Natural Gas (LNG) facility at Prigorodnoye, on Sakhalin Island, in Russia's Far East. The heat exchangers are 40 metres high, and were built in Germany by the Linde engineering company. The LNG facility, the first in Russia, is scheduled to begin operating in the summer of 2008. Photographed in 2005.
