a technical economic and environmental assessment of amine based co2 capture technology for power plant greenhouse gas Control
Environmental Science & Technology, 2002Co-Authors: Edward S RubinAbstract:Capture and sequestration of CO 2 from fossil fuel power plants is gaining widespread interest as a potential method of Controlling greenhouse gas emissions. Performance and cost models of an amine (MEA)-based CO 2 absorption system for postcombustion flue gas applications have been developed and integrated with an existing power plant modeling framework that includes Multipollutant Control technologies for other regulated emissions. The integrated model has been applied to study the feasibility and cost of carbon capture and sequestration at both new and existing coal-burning power plants. The cost of carbon avoidance was shown to depend strongly on assumptions about the reference plant design, details of the CO 2 capture system design, interactions with other pollution Control systems, and method of CO 2 storage. The CO 2 avoidance cost for retrofit systems was found to be generally higher than for new plants, mainly because of the higher energy penalty resulting from less efficient heat integration as well as site-specific difficulties typically encountered in retrofit applications. For all cases, a small reduction in CO 2 capture cost was afforded by the SO 2 emission trading credits generated by amine-based capture systems. Efforts are underway to model a broader suite of carbon capture and sequestration technologies for more comprehensive assessments in the context of Multipollutant environmental management.

designing a hierarchical decentralized system for distributing large scale cross sector and Multipollutant Control accountabilities
IEEE Systems Journal, 2017Co-Authors: Chialin ChenAbstract:Distributing large-scale, cross-sector, and Multipollutant Control accountabilities for meeting the emission reduction targets in accordance with international agreements, such as the Kyoto Protocol and the Convention on Long-Range Transboundary Air Pollution, is a critical emerging issue in sustainable development today. In this paper, we present an innovative hierarchical system design for distributing the centrally optimal cross-sector Multipollutant Control accountabilities. We show that a decentralized hierarchical system can be designed with a bilevel planning structure to induce different industries to “voluntarily” make the centrally optimal abatement choices to meet the national or international Multipollutant emission targets without using the traditional command-and-Control mechanism. We also show the equivalence between the solutions to the two problems as well as the detailed steps to create a globally optimal sharing and coordinating system enabled by industries' endogenous abatement choices according to their own cost structures and technology capabilities. Based on the empirical data from Chinese industries for meeting the national emission targets of multiple pollutants specified in the 11th Five-Year Plan of China, we analyze and compare the economic and environmental performances of the proposed hierarchical system and the status-quo command-and-Control system. The advantages of the proposed hierarchical system in implementation and flexibility are also discussed.

mercury Control technologies for coal combustion and gasification systems
Fuel, 2010Co-Authors: John H Pavlish, Lucinda L Hamre, Ye ZhuangAbstract:Development and testing of mercury Control technologies have largely focused on coal-fired combustion systems, with less emphasis on advanced power systems. Mercury Control is influenced by coal properties and chemistry, plant configuration, pollution Control devices, flue gas conditions, and plant operations, which differ between combustion and gasification systems. Sorbents such as treated activated carbons have shown promising results in low-temperature environments; however, elevated temperature and reducing environments of many advanced systems remain challenging, requiring research and development to obtain acceptable mercury Control levels. Concurrent pollutant/Multipollutant Control strategies that include CO2 Control are critically needed for both conventional and advanced power systems.

mercury emission Control in coal fired plants the role of wet scrubbers
Fuel Processing Technology, 2007Co-Authors: Mercedes Dίazsomoano, S Unterberger, K R G HeinAbstract:When coal is combusted, the combination of the elevated temperature and the volatility of mercury and its compounds results in the presence of gaseous elemental mercury and mercury compounds in the combustion flue gas. In January 2005, the European Commission adopted a mercury strategy that envisages a number of measures to reduce mercury levels in the environment and human exposure. A number of options for mercury removal from coal-fired power plants have been investigated. However, more effort is needed to achieve an efficient and cost-effective technology. The main objective of this work is to investigate the influence of scrubber parameters on mercury removal efficiency to establish effective measures for mercury Control. In order to attain these objectives, theoretical predictions based on thermodynamical equilibrium data and lab-scale experimental tests were carried out. The results obtained point to pH and slurry concentration as the most critical parameters for converting FGD (Flue Gas Desulphurization unit) into a Multipollutant Control technology.

emission limit oriented strategy to Control atmospheric mercury emissions in coal fired power plants toward the implementation of the minamata convention
Environmental Science & Technology, 2018Co-Authors: Shuxiao Wang, Kaiyun Liu, Ji-ming HaoAbstract:Emission limit is a significant index of pollution Control in most countries. However, the determination of a reasonable limit value and corresponding supported technical paths is always a challenge during the implementation procedure. In this study, we developed an emission-limit-oriented strategy which links the emission limit with reduction amount via technical paths, so as to Control the Hg emissions in the coal-fired power plants in China. Results indicate that tightening the emission limit does not always guarantee the reduction of Hg amounts, especially when coal consumptions keep increasing during the economic growth period. By comprehensively considering the feasibility of different technical paths, the emission limit of 5 μg/m3 is recommended to be executed in 2025. Under the guidance of this limit, the reduction amount of emitted Hg will reach as large as 63 t during 2015-2025 by primarily using Multipollutant Control measures. During 2025-2030, both alternative energy measures and specific Hg removal measures will be applied to achieve the emission limit of 1 μg/m3 in 2030. The assessment method developed in this study can be used to establish the emission-limit-oriented Control strategies in other countries or industries, which will assist the success of the Minamata Convention on Mercury.

Mitigation Options of Atmospheric Hg Emissions in China
2018Co-Authors: Shuxiao Wang, Kaiyun Liu, Ji-ming HaoAbstract:As the Minamata Convention on Mercury comes into effect, Controlling atmospheric mercury (Hg) emissions has become a compulsory goal. This study determined the mitigation options for the five Convention specified sources by considering their reduction potential of Hg emissions and the impact of future technology changes on emitted Hg forms and cross-media releases. Hg emissions will be reduced from 371 t in 2015 to 242 t in 2020 mainly by applying Multipollutant Control measures. Hg emissions will be reduced to 71 t in 2030 mainly with alternative measures and specific Hg removal measures (SMR). Alternative measures are effective for the studied sources except waste incineration (WI). SMR is preferentially recommended in cement clinker production due to the benefit of sectoral emissions and local deposition. Stringent requirements of Hg emission Control will promote the use of SMR in WI. In case of nonferrous metal smelting (NFMS), only 8.7 t of Hg emissions will be reduced by SMR. However, the cobenefit of Hg reduction in sulfuric acid and local deposition will increase the relevance. On the contrary, applying SMR in coal-fired power plants (CFPPs) and coal-fired industrial boilers (CFIBs) requires comprehensive evaluation in terms of cost benefit and cross-media effect
