Abstract

This research aims to design and simulate a liquid oxygen (LOX) production line using UniSim Design Suite software. The importance of this study stems from the need to improve the production efficiency of liquid oxygen, which is vital for industrial and medical sectors, while reducing the high costs associated with traditional design methods. An integrated simulation model of the production line was developed, including compressors, heat exchangers, a Joule-Thomson valve, and a separator, relying on the Peng-Robinson equation of state to accurately simulate gas behavior. The results demonstrated the model's capability to produce high-purity liquid oxygen through multi-stage compression, cooling, and sudden expansion processes. This research presents an effective numerical model that can be used as a safe and flexible testing platform to optimize the design of liquid oxygen production units, contributing to cost reduction and the advancement of this vital industry.
