Abstract

This paper discusses the thermodynamic performance of three different system configurations used to expand natural gas from a pressure of above 40 bar to a final pressure of approximately 12 bar: (1) System in which all natural gas passes through a throttling valve, (2) system that uses only an expander as the expansion device, and (3) system using in parallel both an expander and a throttling valve as expansion devices. The sensitivity analysis demonstrates how the mass flow rate of natural gas and the seasonal fluctuation of the ambient temperature affect the thermodynamic efficiency of these systems.
