Liquefied natural gas regasification technologies

Abstract

Environment restrictions of global energy market lead to consider new energy resources. The important aspect is oil, coal transformation to others sources which could be changed by growth of natural gas market. Natural gas is getting as an alternative for changing oil and coal. Looking for better economical perspective, natural gas could be used as LNG, which contains a huge amount of cold energy. Conventionally, this energy is generated during regasification process of LNG and released as wasted energy into atmosphere or dump into seawater. In this paper, reviewed the comparative analysis of LNG regasification technology indicated, that possibility to recover LNG cold energy is the better solution with intermediate fluid vaporizer, which uses special cryogenic fluid. The second part of this paper, the 3‐D numerical model for counter-flow of a single channel in the intermediate fluid vaporizer (Printed Circuit Heat Exchanger) is introduced with governing equations for mass, momentum and energy conservation.
