AN INTEGRATED BENCHMARKING AND ENERGY SAVINGS TOOL FOR THE IRON AND STEEL INDUSTRY

摘要

Benchmarking can be a useful tool for understanding energy consumption patterns in an industrial facility and for designing policies to improve energy efficiency. Energy benchmarking for industry is a process in which the energy performance of an individual plant is compared against a common metric that represents 'standard' or 'optimal' performance. While benchmarking provides insights into the relative energy performance of the plant, it is also a good skirting point for analysis of further improvement opportunities. In this paper, the development of an integrated benchmarking and energy efficiency evaluation tool, named BEST (Benchmarking and Energy Savings Tool), is described. The tool is based on a process-step benchmarking approach that allows for a wide variety of differences in feedstocks and products to be included in a fair comparison. BEST has been developed to support two Chinese integrated iron and steel plants in designing a strategic energy management program. BEST has been successfully applied to develop strategic energy-efficiency improvement targets. We describe the tool and report on its use.
