The simulation using computer software in simulating LNG processes becomes quite popular among researchers today. Publications regarding this field using open-sourced as their simulation platform are yet to be viewed. This paper simulated the energy analysis on PRICO LNG process and compare with an existing results from another publication on the similar topic that use proprietary software. The coefficient of performance value (COP) was obtained and compared with that existing results to examine which platform performs better or at least have same ability. The COP for PRICO through DWSIM was 0.59 and through Aspen Plus was 0.44 hence proved the similar performance of the open and proprietary source platform.
