| Abstract | In this paper, a generic logical model of the liquefaction cycle in an LNG FPSO is proposed to automatically generate various alternatives to such cycle. The generic logical model, which has rules for combining equipment for the liquefaction cycle, is represented by the system entity structure (SES), an ontological framework that hierarchically represents the elements of a system and their relationships. Using this generic logical model, process simulation was performed to determine the optimal-i.e., the most effective-operating conditions for the liquefaction cycle. The method based on sequential modular simulation was used for the process simulation. All the equipment for this method were modeled on the DEVS (Discrete Event System Specification) formalism and connected with the logical models of the liquefaction cycles. Various types of liquefaction cycles for the LNG FPSO, including a dual mixed-refrigerant (DMR) cycle, were synthesized, and the optimal operating conditions for these feasible liquefaction cycles were determined through sequential modular simulation in a DEVS environment. |
