Abstract

The Industrial Emission Directive (IED) requires industrial establishments to apply the best available techniques (BATs), and competent environmental authorities to set permit conditions based on the emission levels associated with BATs. However, the Directive provides no tools for the assessment of BATs leading to the determination of BAT at the installation level. This study applies the cross-media effects assessment methodology to assess BATs at the installation level, applicable to all industrial sectors. The methodology considers cross-media impacts, economic evaluations such as initial and operation and maintenance cost, and cost-effectiveness as the assessment criteria and relies on emission data both from the local level and operating installations. As an example of application, the methodology was applied to the BAT selection for reducing dust emissions from the sintering process of the iron and steel production. The BAT options of the integrated bag filter system (BFS) and advanced electrostatic precipitator (ESP) were compared. The results suggested that ESP has lower impacts in the impact categories of acidification potential, photochemical ozone creation potential, and eutrophication potential than BFS. In contrast, BFS has lower impacts on the other categories. However, the results from the economic analyses revealed a remarkable advantage of ESP over BFS. With these findings, it was concluded that the identification of the best abatement option for dust emissions with a particular reference to BAT is a complex issue. Industrial establishments and the competent environmental authorities must consider not only the environmental impacts and economic evaluations but also legal obligations in developing their approach to emission control.

基于跨媒体效应和经济分析的减少烧结矿粉尘排放的评估技术

摘要

《工业排放指令》（IED）要求工业企业采用最佳可行技术（BAT），并由主管的环境主管部门根据与BAT相关的排放水平设置许可条件。但是，该指令未提供评估BAT的工具，因此无法在安装级别确定BAT。本研究采用跨媒体效果评估方法来评估适用于所有工业部门的安装级别的最佳可行技术。该方法将跨媒体影响，经济评估（例如初始和运营与维护成本以及成本效益）作为评估标准，并依赖于本地和运营设施的排放数据。以应用为例 该方法被应用于最佳可行技术的选择，以减少钢铁生产烧结过程中产生的粉尘排放。比较了集成袋式除尘器系统（BFS）和高级静电除尘器（ESP）的BAT选项。结果表明，与BFS相比，ESP在酸化潜力，光化学臭氧产生潜力和富营养化潜力方面的影响较小。相反，BFS对其他类别的影响较小。然而，经济分析的结果表明，ESP优于BFS。根据这些发现，可以得出结论，确定最佳的粉尘排放减排方案，特别是最佳可行技术，是一个复杂的问题。
