Abstract
As compressed natural gas undergoes a decompression process for its final use, a temperature
drop is caused due to the Joule-Thomson effect. This temperature reduction creates an obstruction
in the decompression equipment pipes, interrupting the continuous supply. In this work it is proposed
to increase the temperature of natural gas using a vortex tube and geothermal preheating to
avoid freezing. The technical feasibility of the proposal is determined through a thermodynamic analysis, simulating the energy model through an engineering software. The results show an increase
in the energy efficiency of the system and a reduction of up to one third of the energy that
would be used in a conventional preheating system.
