Modelling And Simulation Of A Liquefied Natural Gas Regasification Plant

Abstract:

This research focused on the modelling and simulation of a liquefied natural gas (LNG) regasification plant using DWSIM software to optimize energy use and improve efficiency. The problem addressed was the energy-intensive nature of LNG regasification and the need for optimizing its processes. The methodology involved developing a process flow diagram using methane as the LNG component and integrating an Organic Rankine Cycle (ORC) for power generation. The system was simulated under varying pressures to analyze its energy consumption. Findings revealed that increasing pressure significantly raises energy demands, with energy consumption for regasification rising from 35,440.2 kW at 60 bar to 98,807.08 kW at 90 bar. The integration of the Organic Rankine Cycle enabled 67,555.3 kW of power generation from waste heat, showcasing the potential for energy recovery. The study concluded that coupling LNG regasification with power generation enhances energy efficiency, and it recommended further optimization of operating pressures, exploration of cold energy recovery technologies, and the minimization of environmental impacts. This research contributes to improving the operational efficiency of LNG regasification plants
