The Future

This article has reviewed the production status, total reductant consumption, raw materials and operation principle indexes of large blast furnaces in China from 2015 to 2016. The developing actuality of Chinese large BFs has been quantitatively analyzed and the existing problems have been proposed clearly. Based on that, maintaining production stable, enhancing the quality of raw materials and improving the operation principles are suggested. Large BFs take advantages of high-quality hot metal, energy saving, cost-cutting, high mechanization and automation levels and are sufficient to meet the challenges of economic crisis, environmental pressure and security risk form the future. Thus, the number of large BFs in China will continue to increase in the future.

Late Nineteenth

This paper measures the growth and relative levels of total factor productivity in the American, British, French, Belgian, and German mineral fuel pig iron industries from 1840 to 1909. The American history was peculiar in that there was little productivity growth betwen 1840 and 1870 and then rapid growth until 1890. Regression models are developed to identify the techniques responsible for the American advance. Much of the American experience is explained by changes in the composition of the available iron ores. An assessment of the international transferability of late-nineteenth-century blast furnace technology is offered.

Physical Absorption

The Corex process is a more environmental-friendly method of pig iron production than the blast-furnace process. Additionally, this technology is accompanied by production of a fuel gas with a LHV twice as high as blast-furnace gas. Corex gas may be a useful fuel in a metallurgical CHP plant including a combined gas-and-steam cycle. The utilization of Corex gas contributes also to a decrease of CO2 emissions, which is an advantage from the viewpoint of the greenhouse effect. Moreover removing CO2 from the gas before its consumption can allow a further reduction of greenhouse issues. The paper considers the application of two methods of CO2 removal, namely “physical absorption (Selexol solvent)” and “cryogenic gas separation”. The effect of CO2 removal on the operation of CHP plants has been investigated. The removal of CO2 affects first of all the quality of fuel gas in comparison with the raw Corex gas. However, the CO2-removal installation is characterized by a considerable power consumption. Thus the net power and the efficiency of the CHP plant are reduced. Comparing the two considered methods of CO2 removal the cryogenic separation method requires more input energy, but in some cases liquefied CO2 may be an attractive agent. The paper contains the results of a quantitative analysis of the application of these two CO2-removal methods in the Corex technology and their effect on the exploitation characteristics of CHP plants fired with Corex gas.
