铝冶炼厂PFC排放计算结果影响因素探讨

Discussions on factors affecting evaluation results PFC emission from aluminium smelters

PFC是强的温室气体,具有很高的全球变暖潜值,世界铝行业都在努力减少PFC的排放。联合国政府间气候变化专门委员会(IPCC)提供了3个方法来评估铝冶炼过程中产生的温室气体PFC的排放。本文介绍IPCC提供的3个计算PFC排放的方法,并对影响PFC排放计算结果不确定性的因素进行分析。了解影响测试结果准确性的因素,有助于建立更为精确的排放清单。

Perfluorocarbons(PFC),being the powerful greenhouse gases with high Global Warming Potentials(GWPs) and exceptionally long atmospheric lifetimes,has been the list which the whole world s aluminium industry are throwing enormous efforts to reduce.The United Nations Intergovernmental Panel on Climate Change(IPCC) provides three approaches for estimation of greenhouse gases from aluminium production.In this paper approaches for PFC emissions evaluation are described and the factors that could cause uncertainty...
