  • Halocarbons: Ozone Depletion and Global Warming Overview
    National Aeronautics and Space Administration Principal Center for Clean Air Act Regulations Halocarbons: Ozone Depletion and Global Warming Overview Halocarbons are chemical compounds containing carbon, one or more halogens, and sometimes hydrogen. Some halocarbons (“ozone depleting substances,” or ODSs) deplete the ozone layer, while others (“greenhouse gases,” or GHGs) are thought to contribute to global warming. Many halocarbons are considered to belong to both categories. Ozone Depleting Substances Stratospheric ozone is constantly being created and destroyed through natural cycles. Various ODSs, however, accelerate the destruction processes, resulting in lower-than-normal ozone levels. The ozone depletion potential (ODP) is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of chlorofluorocarbon (CFC) 11. Class I ODSs typically have an ODP of greater than 0.1 and include CFCs, halons, carbon tetrachloride, methyl chloroform, methyl bromide, hydrobromofluorocarbons (HBFCs), and chlorobromomethane. Class II ODSs are hydrochlorofluorocarbons (HCFCs). They deplete stratospheric ozone, but to a lesser extent than most Class I ODSs. HCFCs generally have ODPs of 0.1 or less. Selected timeline elements for ODS phase-out are shown in Exhibit 1. EXHIBIT 1 ODS Phase-out Timeline United States Montreal Protocol ODS US HCFC Consumption Allowed Date No Production or Importation of: Date Class ODP-weighted Metric Tons (OMT) 1/1/1994 Halons I CFCs, carbon tetrachloride, methyl chloroform, HBFCs (some 1/1/1996

  • Liquid Level Sensor AKS 4100/4100U
    MAKING MODERN LIVING POSSIBLE Technical brochure Liquid Level Sensor AKS 4100/4100U The AKS 4100/4100U liquid level sensor is designed AKS 4100/4100U - Cable Version AKS 4100/4100U - Coaxial Version specifically to measure liquid levels in a wide range of refrigeration applications. The AKS 4100/4100U liquid level sensor is based on a proven techhology called Time Domain Reflectometry (TDR) or Guided Micro Wave. AKS 4100/4100U liquid level sensor can be used to measure the liquid level of many different refrigerants in vessels, accumulators, receivers, standpipes, etc. The electrical output is a 2-wired, loop powered 4-20 mA output signal, which is proportional to the refrigerant liquid level. AKS 4100/4100U in a cable version is suitable for most commonly used refrigerants, including R717(ammonia), HCFC, HFC and non corrosive gases/ liquids except CO2, and differing lengths from 800 mm(31.5 in.) and up to 5000 mm (197 in.). The coaxial version of AKS 4100/4100U is designed for use with CO2. It can also be used for all other appoved commonly used refrigerants. The AKS 4100/4100U coaxial version should always be used for marine applications for all refrigerant types. The AKS 4100/4100U cable version should NOT be used for CO2 or marine applications. Dust, foam, vapour, agitated surfaces, boiling surfaces, changes in density or in the dielectric constant , εr, for the liquid have no influence on the AKS 4100/4100U performance. Oil accumulated in the bottom of a standpipe will not disturb the liquid level signal and it is not necessary to remove AKS 4100/4100U for cleaning after oil has been drained out of the standpipe.

However, significant global warming potential (GWP), ⁓23,900 times that despite significant research efforts focused on characterisation of of CO2. A systematic and comprehensive investigation of the the breakdown parameters and properties of complex gas-filled characteristics and parameters of the flashover events across HV systems, the basic mechanisms which underpin the solid-gas interfaces in environmentally friendly gases, and in development of discharges in such solid-gas topologies are not fully gases with low (as compared with SF6) GWP values, is required understood. This lack of knowledge is particularly noticeable in for further understanding, optimisation and coordination of the case of solid-gas interfaces stressed with high voltage impulses. The present study is aimed at the experimental investigation of the dielectric insulation in different practical, gas-filled, HV power breakdown behavior of solid-gas interfaces, formed between solid and pulsed power systems and their elements, [1], [2].

Because of environmental priorities defined by international agreements such as the Kyoto Protocol and Doha Amendment, the restrictions on the use of SF6 make these studies an obligation. Although the number of alternative dielectric gases studied for this purpose is quite high, these gases can be classified under the titles of non-synthetics, hydrocarbons (HCs), fluorocarbons (FCs), hydrofluorocarbons (HFCs), fluoronitriles (FNs), fluoroketones (FKs) and other synthetic gases. In this study, the gases classified under these titles are compared using the dielectric constant relative to SF6, Global Warming Potential (GWP), atmospheric lifetime, boiling point and toxicity parameters used in the comparison of dielectric gases. When compared with these parameters, non-synthetic air, CO2, and N2, C3F7CN from FNs, and C5F10O and C6F12O from FKs stand out among alternative gases to SF6.

Therefore, SF6 remains the highest GWP compound identified to date. For decades, SF6 has been a preferred dielectric gas used in many electrical power applications, including medium Research on insulating gases had continued even after the voltage gas-insulated equipment. However, SF6 has an introduction of SF6. This effort took on greater urgency extremely long atmospheric lifetime and has been after governments in various regions began to establish policies to limit SF emissions beginning in the late 1990s recognized as a potent greenhouse gas. As a result, 6 with its inclusion in the Kyoto Protocol. Identification of a governments have sought to reduce emissions from gas- viable alternative to SF6 is complicated by the unique filled equipment. The electrical power industry has combination of properties required in electric power demonstrated a willingness to respond to this applications. The material needs to be nonflammable and environmental issue. Emission rates from gas-filled low enough in toxicity to allow for handling using equipment have been reduced. Progress has been made practices similar to those currently used within the but complete elimination of emissions will not occur until industry. An alternative compound needs to have very high alternative technologies are implemented for SF6 in dielectric strength, as close to the performance of SF6 as electrical power applications.

  • Emissions of Substitutes for Ozone-Depleting Substances
    Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories EMISSIONS OF SUBSTITUTES FOR OZONE-DEPLETING SUBSTANCES ACKNOWLEDGEMENTS This paper was written by Reynaldo Forte, Jr. (USEPA), Archie McCulloch (ICI Chemicals & Polymers, Ltd.), and Pauline Midgley (M&D Consulting). Several reviewers made valuable comments on draft versions of this paper, including Stephen Seidel (USEPA), Thomas Martinsen (IPCC/OECD/IEA Inventories Programme) and Dina Kruger (USEPA). ABSTRACT Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur hexafluoride (SF6) are emitted from a number of end use sectors in which they substitute for ozone-depleting substances. These include refrigeration, air conditioning, aerosol applications, fire suppression, foam blowing, sterilants, and solvents. Emissions of these gases may occur within a year of sale or gradually over several years depending on the application. Aerosols, open-cell foam blowing, and solvents are typical sectors where the chemical is rapidly emitted, while these emissions may be delayed for decades in refrigeration, fire suppression and closed-cell foam blowing. Recovery, recycling and destruction can further delay or eliminate the release of these gases into the atmosphere. The Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC Guidelines) include two methods: • The Tier 1 or “potential” method estimates emissions as being equal to current chemical consumption, where consumption is defined as chemical production plus imports minus exports and destruction. This method of calculating national emissions is simple to perform and recognises that all material consumed has the potential of being emitted eventually, but it seriously distorts the timing of emission by assuming that it occurs when the chemical is first consumed.
