|Abstract:||Scope of this work is to present methods of processing LNG in a plant where its cryogenic content is recovered, mainly to generate power and/or to improve power generation. The energy market will continue to be pushed by a continuously increasing demand. According to a forecast published by U.S. EIA (International Energy Outlook 2010 – Highlights, U.S. Energy Information Administration, release date: May 25, 2010), after the recession that began in 2007 and continued in 2009 causing a world energy demand contraction in the near term, the world energy consumption is expected to increase by 49% from 2007 to 2035 (in particular an 84% increase will occur in nations outside the Organization for Economic Cooperation and Development). World net electricity generation is presumed to significantly increase by 2035. Moreover the tendency, particularly evident in Italy, is to reconvert fuel oil and coal plants into combined cycles: as it is well known natural gas is the fossil fuel preferred in that type of power stations; and for that reason it is increasing its weight among the energetic sources. This consideration has led us to value if it is convenient and feasible to integrate the production of the electric energy and the regasification of LNG, being gas and electricity two goods whose demand grows in the same way. Use of LNG as cold source of an integrated power cycle should allow to avoid the energetic waste due to the conventional regasification recovering part of the energy utilized in the liquefaction process.|
