Abstract

For natural gas to be transported, stored, and used safely, purification is an essential step. The efficiency and environmental sustainability of traditional separation processes are frequently limited. This work investigates a cutting-edge cryogenic technique for deep purification of natural gas that uses liquid nitrogen. This technology’s hydromechanical and heat exchange processes are covered in the paper, along with its benefits in terms of effectiveness, selectivity, and environmental friendliness. Heat exchange mechanisms and the hydrodynamic behavior of gas flow when in contact with liquid nitrogen are modeled mathematically as part of the analysis. Simulations and experimental studies indicate that this approach lowers the process’s overall energy consumption while simultaneously increasing the final product’s purity. The results are intended to aid in the advancement of more sustainable and efficient gas purification systems.
