| Abstract: | The pipeline gas pressure can be recovered as electricity by installing a turbo-expander in parallel with throttle valves at pressure reduction stations. This paper aims to provide a techno-economic assessment of electricity generation at a gas pressure reduction station. Owing to the gas flow rate of the station, technical assessment showed two installation capacities of 2853 kw (Case I) and 4169 kw (Case II). As a result, NPV and IRR for Case I is calculated €1,669,623.93 and 28.95%; and for Case II, NPV and IRR is €1,393,871.91 and 23.91% respectively. The analysis indicated case I is more profitable than case II. |
