Current State of Gas Resource Utilization and Countermeasures of Energy Saving for Integrated Iron and Steel Works in China

摘要

Gas is an important secondary energy in integrated iron and steel works. In this paper we proposed the reasons for low gas utilization by analyzing the characteristics and recycling situation of gas resource. One is the relatively backward idea, the other is that the ways and means of optimizing gas utilization are also backward, then we come up with the countermeasures to improve gas resource utilization. First of all we should promote energy conservation of enterprise system, optimize comprehensive utilization of gas and improve the energy structure. Second is putting more investment in new technology development and take active use of new technology and new process, such as high temperature air combustion technology, combined cycle power plant technology, enriched technology of blast furnace gas and so on. Last is developing gas deep processing to promote co-products of steel and chemical industry. The high added-value chemical products can be obtained by technologies such as production of hydrogen and methyl alcohol with coke oven gas, synthesis of methanol and dimethyl ether with converter gas and so on.
