“…Even during the production stage, greenhouse gas emissions are significant. In 2013, the carbon dioxide emissions during oil production and processing were estimated to be 130 kg CO 2 per Ton of Oil Equivalent (TOE) [30,31]. For each ton of hydrocarbon production, there would be release of 1 kg of methane, and 0.4 kg of nitrogen oxides [30].…”

Though refineries and petrochemical industries meet society's energy demands and produce a range of useful chemicals, they can also affect air quality. The World Health Organization (WHO) has identified polluted air as the single largest environmental risk, and hence it is necessary to strive for and maintain good air quality. To manage potential health impacts, it is important to implement proper air quality management by understanding the link between specific pollutant sources and resulting population exposures. These industries release pollutants such as Volatile Organic Compounds, greenhouse gases and particulate matter, from various parts of their operations. Air quality should be monitored and controlled more meticulously in developing nations where increased energy demands, industrialization and overpopulation has led to more emissions and lower air quality. This paper presents a review of findings and highlights from various studies on air quality impacts of petroleum refining and petrochemical plants in many regions in the world.

“…We use e CO 2 ¼ 0.65 [kg CO 2 /kW he], which is the average value in the Middle East. 45 Consequently, with the assumption of CO 2 emission penalty, the NPV of the hydrocarbon production system can be modied as follows (F ¼ modied NPV)…”

We suggest alternative objective functions based on the concept of thermoeconomics (or exergoeconomics) that could be used for simultaneous maximization of economics and energy efficiency of oil-production systems. The suggested functions are evaluated for an oil reservoir, where water is injected to improve its recovery factor. We find that life-cycle optimization of water-injection projects in terms of net present value (NPV) and net cumulative exergy (NCE) leads to consistent results.We show that managing reservoirs based on a long-term objective leads to significant reduction in their CO 2 footprint. For oil production by water injection, commitment to reduce CO 2 emission provides an opportunity to maximize the NPV of these projects. The sustainability of water injection into hydrocarbon reservoirs is highly dependent on the volumes of the injected and produced liquids. Above a critical water cut (80% in this study), the energy efficiency of the project decreases dramatically, and its CO 2 footprint increases exponentially.

“…Serious environmental challenges and a plummeting international oil price facing the market, have put the offshore oil industry in a dilemma: how to mitigate the CO 2 emissions from offshore oil projects without increasing the capital expenditure significantly [1]. In Norway, about 62% of the carbon dioxide emissions in 2012 came from offshore oil extraction and processing tasks [2]. As a result, a lot of efforts have been put into developing energy efficient technologies to mitigate the CO 2 emissions in offshore oil facilities.…”

With the introduction of new technologies, such as waste heat recovery units (WHRU), associated gas utilization, the energy flow coupling relationship is further deepened within the energy system of the offshore oil and gas production platform. Besides, the energy system is closely linked with the oil and gas production system, and a closed-loop relationship between energy flow and material flow can be revealed. Uncertainties of energy supply and production process may lead to system-wide fluctuations, which threaten the stable operation of the platform. Therefore, an optimal planning model of integrated energy system for offshore oil and gas production platform is proposed in this paper. Firstly, a generalized energy and material flow model is proposed, three matrixes are defined based on laws of thermodynamics, including energy matrix, process matrix and feedback matrix. Secondly, the energy-material conversion relationship between the energy system and production system of a typical offshore oil and gas platform is quantitatively described, together with the coupling between the input and output of the two systems. Thirdly, considering the energy-material balance constraints and the uncertainties of production system, a multi-objective stochastic planning model for the offshore integrated energy system is established, which takes economics and environmental protection into consideration. A Monte Carlo simulation-based NSGA-II algorithm is proposed to solve the model. Finally, the validity and feasibility of the proposed methodology are demonstrated through an offshore oil and gas platform in Bohai, China. Compared with the traditional planning method, the total cost and CO2 emissions of the proposed method are reduced by 18.9% and 17.3%, respectively.
