Sažetak
Oil companies are facing the problem of allowed carbon dioxide emissions because of high-energy consumption or gas flaring. Green (or greener) technology, in the case of oil and gas companies became one of the key parts of their business strategy, often by comprising (or by equalizing) energy sustainability with sustainability of a business. There are three main categories of air pollutants in upstream and downstream activities: fuel combustion, fugitive emissions and carbon dioxide separated at natural gas processing plants. In refineries, boilers in which fuels are oxidized, in order to generate heat for internal separate use, are major contributors to CO2 emission from fuel combustion. Fugitive emissions are mostly related to emissions of methane during oil production (flaring, leakage at seals in flanges, valves etc. or depressurizing releases during blow down in pressure vessels or oil production wells). Gas processing plants in Croatia are producing significant amount of CO2 which after purification could be used for Enhanced Oil Recovery (EOR). In order to review the options for CO2 emission reduction during upstream (and part of mid-stream) operations it should be considered that burning 1 m3 of diesel will result in about 2.5 tonnes of CO2 and that flaring of 1 m3 of gas (at standard conditions) generates around 2 kg of CO2. Possible strategy that oil and gas companies can use to deal with challenges from climate change regulations was analyzed in this work. Additionally, results of case study of CO2 emissions for a different gas composition burned at flaring system in Croatia, and amounts of CO2 at gas processing plants that could be reduced were analyzed. Also, economic analysis with net present value of different technological investments was conducted.
