Liquefied natural gas (LNG) demand has been rapidly increasing due to the global need for clean energy resources. This study analyzes and compares LNG regasification processes and technologies from the technoeconomic perspective and focuses on utilizing LNG cold energy as an economically beneficial option. The comparative technoeconomic analyses focus on the following three process: (1) a simple LNG regasification process, which wastes LNG cold energy; (2) an LNG regasification power plant (LPP)
Natural gas is transported in its liquid state over long distances and thus must be gasified before use. This study focused on the alternative use of cold energy in an LNG regasification power plant integrated with a cryogenic energy storage (LPCES) system that supports variation over time. Energy demands change over time; these dynamics must be considered to improve overall energy efficiency. During off-peak times, the LNG cold energy is stored in the cryogenic energy storage (CES) system. In c
Lactide synthesis is an energy-intensive process used to produce polylactic acid (PLA). In this study, we propose a continuous lactide synthesis process developed on the basis of a recently developed one-step reaction using a SnO2–SiO2 nanocomposite catalyst. This process enables a rapid reaction time of 40 ms for the catalyst, which achieves 94% lactide yield. To design an efficient chemical process, reaction kinetics were developed and a heterogeneous reactor model was applied to the reactor.
