LNG Terminal Operator's Design Feedbacks and Technical Challenges
摘要
Pyeong-taek Terminal II (560,000m 3 and 720 t/h) is now under construction in order to comply with the abruptly increasing gas demand in Korea. For the optimum design of the new terminal, the impacts of the main equipment’s reliability and availability on both the stream line availability and construction and operating costs have been carefully evaluated. Other important design parameters, such as the variation of the imported LNG heating values and the high seasonal gas sendout demand, have also been optimized in the new terminal design. This paper presents the practical design improvements that have been directly applied to Pyeong-taek Terminal II in order to reduce costs and to enhance the terminal’s availability. These involve economical vapor handling and re-condensing, zero emission of LNG vaporization, and an optimum sparing level of the main equipment based on an actual 18-year operating record of reliability and availability of the main equipment.
