Retrofit designs of existing LNG regasification process are suggested. Conventional LNG regasification process is analyzed by exergy decomposition method, followed by the same analyses on three alternative processes. That is, four independent processes are designed, analyzed, and evaluated. Three of them, i.e., conventional LNG regasification process, dual Brayton cycle, and Organic Rankine Cycle, are based on the process presented in literature and the other one is newly integrated, retrofitted scheme for LNG regasification, with a gas-to-liquid (GTL) process. The overall rational exergetic efficiencies are, in order, 0.847, 0.890, 0.849, and 0.868, respectively.
