Researchers from the University of Birmingham have designed a novel adaptation for existing iron and steel furnaces that could reduce carbon dioxide (CO2<\/sub>) emissions from the steelmaking industry by nearly 90%. <\/p>\n\n\n\n

In a press release<\/a>, the university explained that this radical reduction is achieved through a \u2018closed loop\u2019 carbon recycling system, which could replace 90 percent of the coke typically used in current blast furnace-basic oxygen furnace systems and produces oxygen as a byproduct.<\/p>\n\n\n\n

Devised by Professor Yulong Ding and Dr Harriet Kildahl from the University of Birmingham\u2019s\u00a0School of Chemical Engineering<\/a>, the system is detailed in a\u00a0paper published in the Journal of Cleaner Production<\/a>, which shows that if implemented in the UK alone, it could deliver cost savings of \u00a31.28 billion in 5 years while reducing overall UK emissions by 2.9 percent.<\/p>\n\n\n

Less risk and more savings<\/h2>\n\n\n\n

Professor Ding said: \u201cCurrent proposals for decarbonizing the steel sector rely on phasing out existing plants and introducing electric arc furnaces powered by renewable electricity. However, an electric arc furnace plant can cost over \u00a31 billion to build, which makes this switch economically unfeasible in the time remaining to meet the Paris Climate Agreement. The system we are proposing can be retrofitted to existing plants, which reduces the risk of stranded assets, and both the reduction in CO2<\/sub>, and the cost savings, are seen immediately.\u201d<\/p>\n\n\n\n

Most of the world\u2019s steel is produced via blast furnaces which make iron from iron ore and basic oxygen furnaces which turn that iron into steel.<\/p>\n\n\n\n

The process is inherently carbon-intensive, using metallurgical coke produced by destructive distillation of coal in a coke oven, which reacts with the oxygen in the hot air blast to produce carbon monoxide. This reacts with the iron ore in the furnace to produce CO2<\/sub>. The top gas from the furnace contains mainly nitrogen, CO and CO2<\/sub>, which is burned to raise the air blast temperature up to 1200 to 1350o<\/sup>C in a hot stove before blown to the furnace, with the CO2<\/sub>\u00a0and N2<\/sub>\u00a0(also containing NOx) emitted to the environment.<\/p>\n\n\n

What perovskite does<\/h2>\n\n\n\n

The novel recycling system captures the CO2<\/sub>\u00a0from the top gas and reduces it to CO using a crystalline mineral lattice known as a \u2018perovskite\u2019 material. The material was chosen as the reactions take place within a range of temperatures (700-800o<\/sup>C) that can be powered by renewable energy sources and generated using heat exchangers connected to the blast furnaces.<\/p>\n\n\n\n

Under a high concentration of CO2<\/sub>, the perovskite splits CO2 into oxygen, which is absorbed into the lattice, and CO, which is fed back into the blast furnace. The perovskite can be regenerated to its original form in a chemical reaction that takes place in a low-oxygen environment. The oxygen produced can be used in the basic oxygen furnace to produce steel.<\/p>\n\n\n\n

Iron and steelmaking is the biggest emitter of CO2 <\/sub>of all foundation industrial sectors, accounting for 9% of global emissions. According to the International Renewable Energy Agency (IRENA), it must achieve a 90% reduction in emissions by 2050 to limit global warming to 1.5\u00b0C.<\/p>\n\n\n\n
