摘要

This study presents a novel integration of self-sufficient LNG regasification (LNG-R) with a cryogenic air separation unit (ASU), aimed at reducing overall energy demands and enhancing efficiency of the integrated plant. Through a rigorous parametric analysis and optimization using the Teaching–Learning Self-study Optimization (TLSO) algorithm, the integrated self-sufficient LNG-R and ASU system demonstrated significant reductions in energy consumption and reliance on external utilities. The proposed integrated system achieves a specific energy consumption of 0.0221 kWh/kg-Air, with a 0.765 Air/LNG ratio, separating 2754 kg/hr of air and yielding gaseous nitrogen and liquid oxygen with a purity of 99.9%. The process exhibits a coefficient of performance (COP) of 1.33 and an overall exergetic efficiency of 91.2%. This novel LNG-R and ASU integration enhances energy, exergy, and economic efficiency, offering a competitive strategy for optimizing LNG cold energy utilization.
