This paper studied the preparation of chemical raw materials–methanol using blast furnace gas obtained from steel production process. The energy saving and emission reduction effect and the economic benefit brought by the co-hydrogenation process of a mixture of CO and CO2 (CHP) has been compared with those brought by the respective hydrogenation process of CO and CO2 (RHP). The result shows that the CHP brings more economic benefit than the RHP, and the CHP brings more energy saving and emission reduction effect than the RHP.

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflect the energy-saving and emission reduction effect of coal combustion power plant overall. For example, the same coal combustion unit, the coal consumption rate is difference when desulfuration system is operating or not; the coal consumption rate of the unit with SCR will be increased; the coal consumption rate of the air-cooled unit is higher than water-cooled unit; etc.. This paper considers synthetically coal consumption rate, pollution emission, water resource wastage, etc., establishes a integrated evaluation system, adopts factor analysis method, gets the integrated evaluation system and index of energy-saving and emission reduction of coal combustion power generation, evaluates energy-saving and emission reduction effect of 5 power plants reasonable. The results show that the index can reflect the energy-saving and emission reduction level of coal combustion power generation.

Industrial Symbiosis

The biggest challenge for our society, in order to foster the sustainable circular economy, is the efficient recycling of wastes from industrial, commercial, domestic and other streams. The transition to a circular economy is the goal of the European Commission’s Circular Economy Action, which was first launched in 2015. In 2020 the above action plan announced initiatives along the entire life cycle of the product, with the aim to make sustainable products the norm in the EU. Therefore, it is anticipated that the above action will result in an increase in Europe’s economic competitiveness, sustainability, resource efficiency and resource security. Within this context, the suitability of ferroalumina as a raw material in the blast furnace is investigated. Ferroalumina is the product of the high-pressure filter press dewatering process of the Greek red mud generated during the production of alumina by means of the Bayer cycle. Ferroalumina is a low-cost raw material and its possible charging in the blast furnace and/or steelmaking aggregates is a step towards industrial symbiosis, where the wastes, namely by-products, of an industry or an industrial process, become the raw materials for another. In the present work the effect of ferroalumina addition as a raw material was examined by smelting ferroalumina, blast furnace-slag, lime and scrap at 1550°C in a graphite crucible and a constant slag basicity. The increase of the alumina content in the slag improves the desulfurization capacity. Moreover, the silicon exchange between slag and metal was examined. The results indicate that the alkalis’ capacity of the slag increases with the addition of ferroalumina. The analysis of the finally obtained slag suggests that it could be suitable for utilization in slag-cement production.

Blast Furnace Gas

To combat global warming, industry needs to find ways to reduce its carbon footprint. One way this can be done is by re-use of industrial flue gasses to produce value-added chemicals. Prime example feedstocks for the chemical industry are the three flue gasses produced during conventional steel production: blast furnace gas (BFG), basic oxygen furnace gas (BOFG), and coke oven gas (COG), due to their relatively high CO, CO2, or H2 content, allowing the production of carbon-based chemicals such as methanol or polymers. It is essential to know for decision-makers if using steel mill gas as a feedstock is more economically favorable and offers a lower global warming impact than benchmark CO and H2. Also, crucial information is which of the three steel mill gasses is the most favorable and under what conditions. This study presents a method for the estimation of the economic value and global warming impact of steel mill gasses, depending on the amount of steel mill gas being utilized by the steel production plant for different purposes at a given time and the economic cost and greenhouse gas (GHG) emissions required to replace these usages. Furthermore, this paper investigates storage solutions for steel mill gas. Replacement cost per ton of CO is found to be less than the benchmark for both BFG (50–70 €/ton) and BOFG (100–130 €/ton), and replacement cost per ton of H2 (1800–2100 €/ton) is slightly less than the benchmark for COG. Of the three kinds of steel mill gas, blast furnace gas is found to be the most economically favorable while also requiring the least emissions to replace per ton of CO and CO2. The GHG emissions replacement required to use BFG (0.43–0.55 tons-CO2-eq./ton CO) is less than for conventional processes to produce CO and CO2, and therefore BFG, in particular, is a potentially desirable chemical feedstock. The method used by this model could also easily be used to determine the value of flue gasses from other industrial plants.

Two kinds of alkynoxymethyl benzyl quaternary ammonium salt (ABQAS) were synthesized by raw materials of paraformaldehyde, propiolic alcohol, organic amine, benzyl chloride and ethanol under nitrogen protection, toluene as carrying agent. The products were characterized by FTIR. According to the characteristics of blast furnace gas pipeline, quaternary ammonium salt type compound corrosion inhibitor formulas were designed, and their corrosion inhibition performance were evaluated by weight-loss method and electrochemical method. The results showed that the products were synthesized as expected, the two kinds of products had excellent inhibition performance to the cathode electrochemical process of A3 carbon steel, and the corrosion inhibition efficiency in simulative blast furnace gas reached to 100%.
