Zimbabwe Greenhouse Gas (GHG) Emissions 1970-2021

Total greenhouse gas emissions in kt of CO2 equivalent are composed of CO2 totals excluding short-cycle biomass burning (such as agricultural waste burning and Savannah burning) but including other biomass burning (such as forest fires, post-burn decay, peat fires and decay of drained peatlands), all anthropogenic CH4 sources, N2O sources and F-gases (HFCs, PFCs and Sulfr hexafluoride). Zimbabwe greenhouse gas (ghg) emissions for 2012 was 72,057.80, a 0.69% increase from 2011.

Reduction of greenhouse gas emissions has become a worldwide issue. Two kinds of nonthermal plasmas—DBD and CPC—were used to abate SF 6 molecules emitted from semiconductor manufacturing processes. As much as 91% of SF 6 removal efficiency could be achieved with DBD. Four additives (Ar, O 2,C 2H 4, and H 2O) for enhancing SF 6 abatement also were investigated.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

Semiconductor Industry | Fluorinated Gas Partnership Programs

Emission SourcesMitigation OptionsRelevant LinksSemiconductor manufacturers use a variety of high GWP gases to create intricate circuitry patterns upon silicon wafers and to rapidly clean chemical vapor deposition (CVD) tool chambers. Semiconductor manufacturing processes use high GWP fluorinated compounds including perfluorocarbons (e.g., CF4, C2F6 and C3F8), hydrofluorocarbons (CHF3, CH3F and CH2F2), nitrogen trifluoride (NF3) and sulfur hexafluoride (gaz sf6). Semiconductor manufacturing processes also use fluorinated heat transfer fluids and nitrous oxide (N2O). Although the use of fluorinated GHGs did not begin until the late 1980s, their application facilitated the development of significantly more complex and faster processing semiconductors. The continued availability and use of these gases is considered to be critical to the future success of the industry. Estimating fluorinated GHG emissions from semiconductor manufacture is complicated and has required a significant and coordinated effort by the industry and governments. I...
