“…Their so-called thermo-environomic design explores trade-offs not only in environmental (eco-indicators) and economic objectives (profit) but also in thermodynamic objectives (thermodynamic efficiency). They found that neither objective alone is sufficient for a balanced process design by applying their framework to CO 2 mitigation in chemical processes and oil and gas plants (105)(106)(107). Pavão et al (108) also chose a derivative-free optimization approach, using a meta-heuristic approach with simulated annealing and particle swarm optimization, to synthesize a heat-exchanger network with minimum cost and environmental impacts.…”

Design in the chemical industry increasingly aims not only at economic but also at environmental targets. Environmental targets are usually best quantified using the standardized, holistic method of life cycle assessment (LCA). The resulting life cycle perspective poses a major challenge to chemical engineering design because the design scope is expanded to include process, product, and supply chain. Here, we first provide a brief tutorial highlighting key elements of LCA. Methods to fill data gaps in LCA are discussed, as capturing the full life cycle is data intensive. On this basis, we review recent methods for integrating LCA into the design of chemical processes, products, and supply chains. Whereas adding LCA as a posteriori tool for decision support can be regarded as established, the integration of LCA into the design process is an active field of research. We present recent advances and derive future challenges for LCA-based design. 203 Annu. Rev. Chem. Biomol. Eng. 2020.11:203-233.

“…Therefore, the ORC and the boiler constitute a heat recovery system of hierarchy, and the higher temperature (from 400 • C to 500 • C) and the lower temperature (from 160 • C to 220 • C) heat can be recovered simultaneously. Moreover, a two-level CO 2 capture unit proposed in [1] for an oil platform is used to mitigate the emissions. The first level is a Pre-CO 2 capture unit with the structure presented in [30], where natural gas is converted into hydrogen.…”

“…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].…”

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.

“…On the Norwegian continental shelf only three such projects were developed [15], as concerns regarding the additional weight, the complexity of the power cycle, and the cost prevailed. A number of other options were more recently proposed and investigated, involving the power plant [16] as well as the processing plant [17]. A way to decarbonize the offshore operation without deeply modifying the power generation system could be to introduce a carbon capture process [18].…”

“…Technical and economic analyses of offshore electrification have been presented [25]. The environmental performance of electrification tends to be analysed with a simplistic approach, for instance associating average values of CO 2 emissions to the power sent offshore [17]. However, the power system is a very integrated system that is predicted to change deeply in the upcoming years.…”

An Integrated Assessment of the Environmental and Economic Impact of Offshore Oil Platform Electrification

et al. 2019

Electrification of offshore oil and gas installations on the Norwegian continental shelf is one of several options to decrease the CO2 emitted from these installations. However, there is an ongoing debate regarding how the increased electricity consumption will influence the CO2 emissions in the power market, both in the short-run and in the long-run. This paper aims to address the issue and investigate the feasibility of the electrification of a large offshore area in the North Sea in comparison to standard concepts to supply energy offshore. A novel integrated model was developed for the purpose that includes and combines a process model of the offshore power generation units and a model of the European power system. The integration of the two models allows to simultaneously simulate the behavior of the offshore energy conversion systems and the effect of electrification on the onshore power system. The outcomes of the analysis show that the environmental performance of electrification is strongly affected by the selected approach to quantify the CO2 emissions associated with power from shore. Taking standard methods to supply offshore energy as basis for comparison, the marginal effect of electrification would result in increased CO2 emissions (+40%), while the average effect would entail large reductions in CO2 emissions (−48% to −90%), the extent of which depends on the geographical scope selected. An analysis on the economics of electrification indicates that its economic viability would be challenging and would not be favoured by a strong European commitment towards environmental policies since the expected increase of power price will outbalance the gains for the reduced emission costs.
