Overview

This research demonstrates enhanced power generation through LNG cold energy recovery, suggesting economic and environmental benefits.

Key Points

  • To explore a novel integrated system for recovering cold energy from LNG for sustainable power generation.
  • Proposed an integrated system utilizing ORC, Kalina, DEC, and Brayton cycles.
  • Conducted thermodynamic and economic simulations with Aspen HYSYS (v12.1).
  • Performed parametric optimization and exergy analysis.
  • Increased power output from 50.74 MW to 64.12 MW after optimization.
  • Achieved a payback period of 5.87 years for economic feasibility.
  • Reduced greenhouse gas emissions and improved energy independence for LNG terminals.
