This article analyzed the potential energy recovery from rather small quantities of associated gas (<2000 m3/h), where the on-site electricity generation within the oil extraction field may represent a cost-effective solution as an alternative to flare combustion. Various power plant technologies were considered and compared from both the economic and avoided CO2 emissions points of view. It turned out that adopting a scheme with non-derated internal-combustion engines (ICE) fed by treated gas, and partial gas flaring, the most cost-effective result was obtained, showing a payback time of about 5 years and an internal rate of return (IRR) of 42.2%.

Abstract
This article analyzed the potential energy recovery from rather small quantities of associated gas (<2000 m3/h), where the on-site electricity generation within the oil extraction field may represent a cost-effective solution as an alternative to flare combustion. Various power plant technologies were considered and compared from both the economic and avoided CO2 emissions points of view. It turned out that adopting a scheme with non-derated internal-combustion engines (ICE) fed by treated gas, and partial gas flaring, the most cost-effective result was obtained, showing a payback time of about 5 years and an internal rate of return (IRR) of 42.2%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
