一项新的国际条约，水稻田公约，将汞(Hg)确定为对人类健康的全球威胁，并寻求控制其排放和排放。燃煤发电厂是全球汞污染的主要来源，预计将成为中国会议根据水稻田公约解决的第一个关键部门。以决策树和每个技术选择的成本效益的形式制定了采用最佳可用技术(BAT)的模型。共同受益控制技术及其与配煤/换煤和注入卤素(HI)的强化可以提供早期措施，帮助中国履行《水稻田公约》的义务。我们预测未来的能源和政策情景，以模拟中国潜在的国家汞减排目标，并估计每种情景下控制措施的成本。相当于美国汞和空气有毒物质标准(MATS)规则的目标的“水稻田中型”方案，要求分别在30%和20%的发电厂上应用活性碳注入(ACI)和HI。相应的总成本为25亿美元，大约是美国成本的四分之一。2030年的排放限值为3微克/立方米(3)，被确定为中国遵守水稻田公约的可行政策选项。(C)2015爱思唯尔有限公司。保留所有权利。
A new international treaty, Minamata Convention, identifies mercury (Hg) as a global threat to human health and seeks to control its releases and emissions. Coal-fired power plants are a major source of mercury pollution worldwide and are expected to be the first key sector to be addressed in China under Minamata Convention. A best available technique (BAT) adoption model was developed in the form of a decision tree and cost-effectiveness for each technological option. Co-benefit control technologies and their enhancement with coal blending/switching and halogen injection (HI) can provide early measures to help China meet the Minamata Convention obligations. We project future energy and policy scenarios to simulate potential national mercury reduction goals for China and estimate costs of the control measures for each scenario. The "Minamata Medium" scenario, equivalent to the goal of the US Mercury and Air Toxics Standards (MATS) rule, requires the application of activated carbon injection (ACI) and HI on 30% and 20% of power plants, respectively. The corresponding total costs would be $2.5 billion, approximately one-fourth the costs in the US. An emission limit of 3 mu g/m(3) in 2030 was identified as a feasible policy option for China to comply with Minamata Convention. (C) 2015 Elsevier Ltd. All rights reserved.
