STUDY ON THE USABILITY AND STORAGE OF LNG

The monograph is dedicated to analyzing the possibilities of using LNG (Liquefied Natural Gas) in the context of current regulations regarding its quality. The publication analyzes selected LNG compositions, taking into account the variability of basic gas parameters, which is crucial due to the differences in the content of individual components while maintaining quality criteria.

• Qualitative analysis and verification of exemplary LNG compositions in terms of legal requirements and recipients.
• Thermodynamic model and heat exchange model for analyzing the mechanisms of heat transfer to LNG.
• Explanation of the aging process of LNG and calculation procedures for the thermophysical properties of the liquid and gaseous phases.
• Method for verifying the aging model of LNG with a comparison of modeling and research results.
• Determination of the quality requirements of LNG as a motor fuel, including the parameters necessary for the operation of gas engines.

The monograph presents a detailed thermodynamic model and a heat exchange model that allow for the analysis of various mechanisms of heat transfer to liquefied natural gas. The phenomenon of LNG aging is also explained, which is essential for the long-term storage and use of this fuel. A calculation procedure is presented that allows for the determination of the thermophysical properties of both the liquid and gaseous phases in the LNG storage tank, which is crucial for optimizing storage and distribution processes.

A method for verifying the LNG aging model is also described, which allows for the assessment of the accuracy and reliability of predictions regarding the weathering of liquefied gas. The results of weathering prediction using modeling were compared with the results from published studies, which further confirms the value of the presented approach. The monograph thoroughly discusses the utility properties of natural gas, in particular its use as a motor fuel.

The quality requirements formulated by potential recipients of LNG as a motor fuel are determined, including the parameters necessary for the proper operation of gas engines. The publication of AGH Publishing House is a valuable source of knowledge for engineers, scientists and specialists dealing with LNG technologies and energy. The authors, Mariusz Łaciak and Tomasz Włodek, present a comprehensive approach to the analysis and evaluation of the possibilities of using LNG, taking into account technical, economic and legal aspects. The book is a valuable contribution to the development of knowledge about liquefied natural gas and its applications.
