  • N2/SF6 gas Mixtures — Large Scale Application in Gas

    The application of N 2 /SF 6 gas mixtures with SF 6 -contents between 10 % and 20 % reduces the costs for the insulating gas remarkably. This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance applications of this technique is improved on the user side.

  • Hot Mix Asphalt Facilities: New Source Performance Standards

    Rule SummaryRule HistoryComplianceOn June 11, 1973 (38 FR 15406), pursuant to section 111 of the Clean Air Act, as amended, the Administrator proposed standards of performance for new and modified stationary sources within seven categories of stationary sources: 1. Asphalt concrete plants, 2. petroleum refineries, 3. storage vessels for petroleum liquids, 4. secondary lead smelters, 5. secondary brass and bronze ingot production plants, 6. iron and steel plants, and 7. sewage treatment plants. In the same publication, the Administrator also proposed amendments to subpart A,General Provisions, and to the Appendix, Test Methods, of 40 CFR Part 60. A Hot Mix Asphalt (HMA) plant can be constructed as a permanent plant, a skid-mounted (easily relocated) plant, or a portable plant. All plants can have Reclaimed Asphalt Pavement (RAP) processing capabilities. Virtually all plants being manufactured today have RAP processing capability. Most plants have the capability to use either gaseous fuels (natural gas) or fuel oil. H...
