摘要

The World Steel Association, along with the OECD, agreed to jointly organise a workshop on Future Priorities for the Global Steel Industry. This is a report of the contribution to be presented by the Russian Federation on greenhouse gas emissions. THE Russian State scientific centre TSNIIchermet (named after I P Bardin) has estimated greenhouse gas (GHG) emissions from steelmaking in Russia for 1990-2009 (estimated using the standard principles of the World Steel Association). The value calculated is 1.639tCO_2eq per tonne of hot metal. This figure for 2009 is down 17.4% on 1990 (Table 1). During the period 1990-2009 considerable work was undertaken to re-structure inefficient steelmaking capacities to improve energy efficiency in the steel sector and decrease GHG emissions. In particular, in 2009, in comparison with 1990, the share of converter steelmaking plus electric arc steelmaking increased from 46.6% to 91.4%, ie doubled in its contribution, while the share of OHF steelmaking decreased from 53.4% to 8.6%, ie a six-fold decrease (Fig 1). The share of continuous cast steel for this period increased from 23.1% to 81.0%, ie an increase of 3.5 times. As a result, in 2009 absolute CO_2 emissions compared with 1990 levels decreased from 177.6Mt to 97.0Mt a reduction of about 45%. Of this, 34.0% was due to a reduction in the volume of output of crude steel and 11.4% due to structural reorganisation of the sector. Specific CO_2 emissions per metric tonne of crude steels have decreased from 1.983t in 1990 to 1.639t or by 17.4% in 2009.

Bardin命名)估计了1990-2009年俄罗斯炼钢的温室气体排放量(使用世界钢铁协会的标准原则估算)。计算得出的值为每吨铁水1.639tCO_2eq。 2009年的这一数字比1990年下降了17.4%(表1)。在1990年至2009年期间,为重组低效的炼钢能力进行了大量工作,以提高钢铁行业的能源效率并减少温室气体排放。特别是,2009年与1990年相比,转炉炼钢和电弧炼钢的份额从46.6%增加到91.4%,即贡献了两倍,而OHF炼钢的份额从53.4%下降到8.6%,即减少了六倍(图1)。在此期间,连续铸钢的份额从23.1%增加到81.0%,即增加了3.5倍。结果,与1990年相比,2009年的绝对CO_2排放量从177.6Mt减少到97.0Mt,减少了约45%。其中,34.0%是由于粗钢产量减少而11.4%是由于该行业的结构重组。每公吨粗钢的特定CO_2排放量已从1990年的1.983吨减少到1.639吨,到2009年减少了17.4%。
