|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. 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. 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, economic and environmental points of view. 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 are of particular importance for the use of LNG.|
Tatiana Morosuk is a Professor at the Technische Universität Berlin, Germany (since 2013). She has done her studies in refrigeration engineering from the Odessa State Academy of Refrigeration, Ukraine, and received her Diploma in 1990, PhD in 1994 and Professorship in 2001. Her field of scientific activities is the application of exergy-based methods to the analysis and improvement the thermodynamic, economic, environmental performance of different power generation systems, refrigeration/cryogenic systems and chemical plants. Particular attention is given to systems associated with the liquefaction of natural gas and the regasification of LNG, smart energy supply and use in industrial parks, including innovative concepts of liquid air energy storage. She is the author or co-author of 7 books and more than 250 publications, and has 10 patents. She has over 20 years of experience and related teaching experience in the fields of refrigeration and over ten years in the field of applied thermodynamics, energy engineering and exergy-based methods.
