MAXIMIZED SYNERGY EFFECTS BY INTEGRATION OF AN LNG TERMINAL AND AN ADJACENT POWER PLANT

摘要

The operational characteristics and seasonal supply patterns of liquefied natural gas (LNG) terminals are different from those of power plants. However, establishing the proper strategy in planning and designing these plants simultaneously can maximize synergies through the combination of LNG terminals and adjacent thermal power plants. This Paper Presents integrated methodologies for maximizing the potential synergy effects on economical investment, cost effective operations, and the mutual contribution for both the plants. The important points to be considered in establishing the strategy are: The mutually compensated operation by different seasonal supply patterns; Reduction in the LNG storage capacity with the role of gas demand swing by power Plants; Reduction in the total construction cost by sharing the facilities; Reduction in environmental impacts; Reduction in energy cost and increase in operational efficiency by supporting different types of energy requirements (condensation and vaporization); Solving contractual difficulties of integrated schemes. This paper analyzes these topics in detail and develops them with practical applications. This integrated methodology provides a useful guideline for establishing a strategy to maximize the synergy effects on the integrated plants.
