2016年10月7日 · Scientists use “PFCs” as an abbreviation for two distinct but related sets of chemicals. Whenever you see the abbreviation, make sure you understand how the author/publisher is using it. “PFCs” can be an abbreviation for either: a subset of perfluorinated chemicals called perfluorocarbons.

Direct HFC emissions occur from sources that are owned or controlled by the company. A step-by-step approach is presented to cover every phase of the calculation process from data gathering to reporting.

Six fully fluorinated compounds (FFCs) and one hydrofluorocarbon are currently widely used by the semiconductor industry: tetrafluoromethane (CF4), hexafluoroethane (C2F6), octafluororopane (C3F8), octafluorobutane (c-C4F8), suflur hexafluoride (SF6) nitrogen trifluoride (NF3) and trifluoromethane (CHF3)2.

2024年4月11日 · Get in-depth insights into Perfluorocarbon (PFC) emissions statistics. Access downloadable reports and interactive data visualizations to explore the impact and solutions. Perfluorocarbons (PFCs) can be produced in the primary aluminium reduction process, during events referred to as anode effects.

2024年10月3日 · EPA has supported the semiconductor industry's voluntary efforts to reduce high GWP greenhouse gas (GHG) emissions. The EPA and the semiconductor industry worked together from 1996 to 2010 through the PFC Reduction Partnership for the Semiconductor Industry to identify a variety of technologies that reduce GHG emissions and …

PFC等はフッ素系温室効果ガス(F-GHG, Fluorinated Greenhouse Gas)とも称されます。 半導体業界と液晶ディスプレイ業界は、同様のプロセス・装置でF-GHGを用いています。

Hydrofluorocarbons (HFCs) and, to a lesser extent, perfluorocarbons (PFCs) are used as substitutes for the regulated ODSs. In addition, some air conditioning and refrigeration systems use non-halogenated refrigerants such as ammonia, carbon …

用于考虑消耗量（潜在排放），此消耗量与包含hfc、pfc和sf6 的产品贸易有关。 如果各国选择开发潜在排放估算，则鼓励这些国家分别跟踪单独的 HFC、PFC 和 SF 6 。

The RAC tool calculates the HFC and PFC emissions from the manufacture, servicing, and/or disposal of RAC equipment. The tool offers three methods: A sales based approach for manufacturers and users; a life cycle stage approach for users; and a basic screening approach that is intended to help companies gauge whether or not their emissions ...

Section 2, describes the physical and chemical characteristics of liquid PFC HTFs for electronic manufacturing. Section 3 presents the history of liquid PFC uses in the electronics sector, which is followed, in Section 4, by detailed descriptions of the current uses, focusing on the quantities used and the factors that govern selection of HTFs.
