Abstract

Statement of the Problem: The overall chain “natural gas − LNG – natural gas” can be divided into four blocks: (a) Export terminal with associated technology for natural gas liquefaction (LNG production),
(b) LNG transport, (c) import terminal using a regasification process, and (d) distribution of the natural gas. Each of those four blocks is associated with energy-intensive processes. During the last two decades the total cost of LNG technology has decreased significantly due to improvements of the liquefaction process. However, the regasification system has not been considerably improved. It is known, that for the conventional regasification process (indirect heat transfer process, for example open rack vaporizers, submerged combustion vaporizers) about 1.5 % of the LNG energy is used. Findings: The integration of LNG regasification into heat utilization systems of an industrial process, LNG-based cogeneration for electricity generation, and LNG-based cogeneration for chemical products will bring benefits for the entire co-generation system (or industrial park) from thermodynamic, econonmic and environmental poits if view. Methodology: Exergy-based methods are applied for analysis, evaluation and improvement the thermodynamic, economic, environmental performance of actual and innovative systems for regasification of LNG. Conclusion & Significance: LNG will have in future a significantly larger contribution to the energy supply in the world than it had in the past. Thus, applying thermodynamically efficient, cost effective, and environmentally benign plants for the regasification of LNG is of particular importance for the use of LNG.
