(539b) Optimizing Design Specification for LNG Receiving Terminal Using Dynamic Simulation

Since the demand for natural gas has been continuously increased due to its cleanness, the construction of LNG receiving terminal which imports and stores LNG in on-shore area also grows up over the world. Although the design specification for LNG receiving terminal needs to be adjusted to the individual characteristics of the terminals such as the whole length of the pipeline, the number of the LNG storage tanks and atmospheric temperature, the systematic approach to determine a design specification to reduce the operating cost seems to be absent. Such various characteristics can make effect on terminal operation, which leads to the change in operating cost including pump and compressor. Because an inadequate operation such as excessive recirculation flow rate or compressor movement brings about increase in operation cost, we need to precisely examine the design factors effecting on operating costs and optimize them for each terminal. In this work, we suggest the systematic methodology for optimal design specification to cope with the various characteristics of LNG receiving terminals. Proposed method contributes to minimize the operating cost in LNG receiving terminal.
