LNG REGASIFICATION - TECHNOLOGY EVALUATION AND COLD ENERGY UTILISATION

摘要

The import of LNG by means of re gasification terminals is an important element needed to meet the current and the future energy demand, globally. Over the past decade, the global LNG industry has grown rapidly both in terms of liquefaction and re gasification capacity. Almost 70 LNG re gasification terminals are now operating in 21 countries worldwide, nearly 20 more are under construction, and approx 30 more have been proposed. The costs, supply reliability and process safety are the key issues for the gas supply in the future. The demand on gas supply costs requires continuous efforts at optimizing the LNG supply chain efficiency and enhanced utilization of the available energy. The current research is undertaken as part of an industry focused PhD program. The research is to study the current technology position on LNG re gasification and identify new opportunities for optimization and utilization of cold (cryogenic) energy. The proposed study is expected to be techno economic in nature. The purpose of this initial paper is to assess the currently operating LNG regasification terminals in terms of the technologies employed and challenges, locational parameters, LNG quality, efficiency and utilization of cold (cryogenic) energy.
