LNG-BASED COGENERATION SYSTEMS. PART 1. COMPARISON OF GAS-TURBINE-BASED CONCEPTS

摘要

Liquefied Natural Gas (LNG) is expected to contribute in future more than in the past to the overall energy supply in the world. The paper is the first part of a two-part presentation. In the first one, some novel concepts for combining LNG regasification with the generation of electricity are discussed, whereas in the second part advanced exergy-based analyses are applied to the most favorable LNG-based cogeneration system. All concepts to be evaluated in the first part use gas turbines, to keep the overall investment cost relatively low. The comparisons are conducted based on thermodynamic efficiency and on the potential for improving this efficiency.
