行业

工业节能数据库涵盖的行业如下:

The chemical and petrochemical sector is the largest industrial energy consumer. Ammonia production is responsible for about 17 percent of the energy consumed in this sector.

水泥是一种胶凝材料,是最常用的人造材料混凝土的主要成份。水泥的需求与经济发展速度有很大关联。水泥制造业是全球第三大能源消耗和二氧化碳排放行业,其在2006年,来源于热能消耗和生产工艺的二氧化碳排放估计为1.9 Gt1 。如果所有水泥厂都采用最佳可获得用技术,则全球能源强度可由目前的平均值3.5 GJ/t-水泥,降低1.1 GJ/t-水泥。这将使二氧化碳排放量减少约119 Mt2

 

钢铁是全球经济的主要产品。自2000年以来,全球粗钢产量增长了75%,2011年1 粗钢产量达到14.9亿吨。钢铁行业是工业二氧化碳排放的最大来源(2006年直接排放量达2.16Gt),也是工业中的第二大能源消费用户(2006年能耗达24EJ)。尽管近几年钢铁行业有了很大的改善,但它仍具备技术潜力,有望进一步将能耗和二氧化碳排放降低约20%,即节省4.7EJ能量以及减少350Mt二氧化碳的排放2

The pulp and paper sector is a significant energy user and currently ranks fourth in the industrial sector for its energy use. In 2006, the sector consumed 6.7 EJ of energy, which represents 6% of global industrial energy use. Despite high energy use, the sector has a low CO2 intensity due to extensive use of biomass as fuel (in 2006, the emissions of the sector reached 184 Mt, representing onlly 3% of global emissions in 20061).

Over the past twenty years, glass demand has grown more quickly than GDP and is still growing at nearly 4% per year. About 0.5 – 0.8 EJ of energy is used for glass production worldwide, and the energy used in the production of container and flat glass results in emissions of about 50 – 601 Mt CO2 per year2.
