SYNTHESIS GAS PRODUCTION IN THE BLAST FURNACE - FEASIBILITY STUDY. DEMONSTRATION PROJECT
This is the final report of a feasibility study carried out in the framework of the European Commission Energy Demonstration Programme. The aim of the study was twofold: to determine whether the conversion of a blast furnace into a gas generator is technically feasible, and to evaluate the approximate cost price of the synthesis gas produced. It has been shown that the existing technique of injecting coal at the level of the tuyeres is directly applicable to coal gasification in the blast furnace. Several operating scenarios have been studied, particularly in the light of the need to maintain an efficient circulation of fluids in the blastfurnace. From the economic viewpoint, the principal advantage of the process is that the capital investment required to convert the blastfurnace into a coal gasifier is relatively small compared to the cost of a conventional gas generator. The former has been estimated at around 20 millions ECU for a production capacity of 80,000 Nm3 per hour (CO f5 H2). If the estimates are confirmed by largescale testing, the cost price of the gas will be 60 % of the cost price, per gigajoule, of gas from normal coal gasification, 67 % of the price of gas from the reforming of natural gas and 64 % of the price of gas from liquid hydrocarbons. A large part of the study deals with the analysis of the potential end uses of the huge quantities of syngas that would have to be used should this technology be applied.
