行业间生态链接协同减排模式与节能效果分析

随着钢铁企业节能环保工作深入推进,钢铁生产流程自身节能减排的潜力已十分有限。而且随着环保要求越来越严格,钢铁企业环保成本压力也越来越大,因此钢铁生产流程排放物资源化、高值化利用的多联产过程协同减排研究越来越受到重视。以钢铁生产流程为核心,以其过程排放物——渣、副产煤气及环保副产物的高值化利用为切入点,构建典型的钢铁-化产-建材多联产过程,分析多联产过程的节能减排效果,为钢铁企业节能减排提供新思路。

Analysis on coordinated emission reduction mode and energy saving effect of ecology chain inter-industry

With the progressing of energy saving and environment protection work in steel entorprises, the energy saving and emission reduction potential of the process itself is limited. While the requirement of environment protection is stricter, the pressure of environment protection cost is higher. Thus, research on coordinated emission reduction of poly-generation process based on reuse and higher value application of waste has become more and more valued. Centered on steel manufactory process, typical metallurgy-building material-chemical engineering poly-generation processes were studied based on the reuse and higher value application of wastes such as slags, gases and by-products of environment protection. The energy saving and emission reduction effect of these poly-generation processes were analyzed, compared with individual processes, poly-generation processes research put forward a new idea for steel enterprise to save energy and reduce emission.
