Natural gas liquefaction is an energy-intensive process. Liquefied natural gas is obtained by reducing the temperature of natural gas to a temperature of -160℃, in this process, the volume of liquefied natural gas reaches 1/600 volume of natural gas. This method is suitable when transporting with the pipeline is difficult and expensive, and by liquefaction and volume reduction, it can be easily transported over long distances. . In this study, by using ASPEN HYSYS software, the PRICO liquefaction cycle, which includes two compressors and a heat exchanger, was simulated. The simulations were performed in two modes of high pressure (7945 Kpa) and low pressure of natural gas (2861 Kpa). The objective function was to minimize the specific energy consumption of the process. The energy consumption was 0.316 kWh / kgLNG, which showed a decrease of 22% compared to the reference value.
