脱硝技术主要分为低NOX燃烧技术和烟气脱硝。烟气脱硝是目前发达国家普遍采用的减少NOX排放的方法,具有很高的脱硝效率,应用较为成熟的有选择性催化还原法(SCR)、选择性非催化还原法(SNCR)、电子束法以及炽热碳还原等技术。SCR(选择性催化还原法)是目前绝对主流的也是商业化最为成功的烟气脱硝技术。 相似文献

大多数企业在其生产活动过程中都不免产生一定量的废气,这些产生的废气直接排放到大气中就不可避免地对空气造成污染,当前的事实是工业生产所产生的废气种类繁多,随着各个国家对环境保护的意识加强,废气治理技术也得以快速地发展,目前针对同一种废气存在着多种治理技术,不同治理技术的性能也会千差万别的。本论文主要介绍了工业废气中有机废气的来源及其危害,并对当前存在的废气治理技术进行了分析,研究不同技术所存在的优势和不足,文章最后对高效率的有机废气处理技术进行了介绍,展望未来有机废气治理技术的前景。 相似文献

本文基于中国除西藏和青海的29个省市区1998~2009年的面板数据,首先利用DEA方法对工业废气治理技术效率及其分解进行测算,然后利用Tobit面板数据模型对工业废气治理纯技术效率和规模效率的影响因素进行分析。研究结果表明,工业废气治理技术效率及其增长率均是西部高于中部,中部高于东部,东部工业废气治理技术效率主要受工业废气治理规模效率的影响。人均GDP等因素对工业废气治理纯技术效率和规模效率都有不同程度的影响。 相似文献

This study examines the Natural Gas Policy Act of 1978 and Federal Energy Regulatory Commission (FERC) policies that culminated
in Order 636 in 1992. The regulatory environment in which natural gas distribution utilities operate was altered. FERC policies
forced local gas distribution utilities into an increasingly competitive environment. Restructuring of the industry may affect
economic efficiency. Data Envelopment Analysis is used to examine the economic efficiency of gas distributors during 1975–94.
Federal policy appears to lead to a reduction in scale due to restructuring and more competition. Reduced scale economies
have not altered the economic efficiency of the utilities. 相似文献

选择性催化还原(SCR)烟气脱硝技术在目前世界上先进的火电厂烟气脱硝主流技术之一。为控制脱硝过程中氨的使用及保护设备,必需监测SCR出口的氨逃逸量。本文通过对氨逃逸在线连续检测技术原理的分析,以某电厂脱硝装置为例,探讨了利用可调谐二极管激光光谱吸收法检测氨逃逸量的在线检测仪表在火电厂SCR脱销的应用。结果表明,采用该测量方法能够准确可靠的检测氨逃逸量,为电厂的安全和高效运行提供保障。 相似文献

Urban-wide gas distribution cost models are developed and estimated, using capital costs, gas market, and population density data over cross-sections of communities served by two different utilities, with a particular emphasis on the multiproduct, multidimensional character of gas distribution: These models are used to clarify such policy issues as the allocation of joint costs through marginal cost pricing, the existence of ecpnomies of scale and density, and the appropriateness of natural monopoly status for gas distribution utilities. 相似文献

The production of shale gas depends not only on shale resources and capital investment but also on having a flexible and stable policy environment. This paper examines whether and how partisan ideology affects the extraction of shale gas. We use panel fixed effects as well as the system–generalized method of moments approach with quarterly panel data from 15 US states over the period 2007−2016. We consider not only the political ideology of the state governor but also the state legislature’s influence on the governor, control over the governorship and the legislature by the same party, the reelection of an incumbent government, and turnover in the political party in power. The results indicate that because the right-leaning party is more likely to support shale gas development, when a member of that party heads the state government, shale gas production performance is higher than when the left-leaning party is in power. Therefore, the production of shale gas rises with a turnover in political control from left to right, reelection of a right-leaning incumbent, and more right-leaning power in the state legislature. We believe our results shed light on the role of partisan ideology in shale gas production, which has implications for environmental regulations. 相似文献
