  • Chemical Decomposition of High Pressure SF6/N2 (5:95

    In order to comply with this aim, one of the solutions adopted by the manufacturers and the users of some of these equipments, consists in reducing the quantity of SF 6 used by mixing it with zero (or very much lower) risk gases.For instance, as SF 6 /N 2 mixtures with SF 6 concentrations lying between 5 and 15% realise a satisfactory compromise between dielectric performances and cost, Electricité de France plans to use these mixtures to fill its future gas-insulated lines 2.

    Executive SummaryIntroductionNature of Industrial Heat Demand and UseThe Difficult Nature of Industrial Markets and PoliciesBackground and DataOptions For Low-Carbon HeatGeneric Cost Estimation: Analysis and ComparisonAdditional Indirect (System) CostsLife-Cycle Assessment ConcernsConsiderations of Specific Industrial ApplicationsRecent studies indicate there is an urgent need to dramatically reduce the greenhouse gas emissions from heavy industrial applications (including cement, steel, petrochemicals, glass and ceramics, and refining). Heavy industry produces roughly 22 percent of global CO₂ emissions. Of these, roughly 40 percent (about 10 percent of total emissions) is the direct consequence of combustion to produce high-quality heat, almost entirely from the combustion of fossil fuels. This is chiefly because these fuels are relatively cheap, are widely available in large volumes, and produce high-temperature heat in great amounts. Many industrial processes require very large amounts of thermal energy at very high temperatures (more than 300°C and often more than 800°C). For example, conventional steel blast furnaces operate at about 1,100°C, and conventional cement kilns operate at about 1,400°C. In addition, many commercial industrial facilities require continuous operation or operation on demand. The...
