Utilization of the cryogenic exergy of liquid natural gas (LNG) for the production of electricity

The economic optimization of the minimum heat transfer temperature difference (pinch value) in particular heat exchangers has been performed and then the optimum heat transfer area of heat exchangers has been calculated. The influence of the changing ambient temperature on the efficiency of the cold power plant has been analyzed. The own cost of the produced electricity, the annual profit and the pay-back of the plant have been evaluated. The attained reduction of CO2 emission in national economy has been calculated. The analysis of the sensitivity of economical profit on the deviation of economic data has been determined.
