The conversion of steel mill off‐gases to base chemicals is a promising perspective to improve the financial return of steelmaking in Europe and fight CO2 emissions. In the Carbon2Chem® joint research project, mathematical models are developed to simulate operation scenarios of cross‐industrial networks and chemical plants embedded in a steel mill environment. Methodically, the modeling follows a multilevel approach combining models of different depth and origin in a common simulation framework. Here, the synthesis of methanol is simulated and analyzed for different gas conditioning scenarios.

Steel is a critical material for many aspects of modern life. Transport systems, communications, civil infrastructure, and industrial engineering could not survive without it, yet the steel industry is reported to be responsible for 5 – 7 % of anthropogenic CO2 emissions making it a major contributor to climate change. Efficient utilization of the carbon rich by‐products of steel production in order to avoid CO2 emissions is vital. Traditionally by‐product gases have been used as fuel‐gas for heating applications or for power generation. Alternative chemical applications are now being developed based upon utilization of the gases as raw materials for chemicals production.

“…Uribe‐Soto et al claimed that the steel industry is the main generator of CO 2 among the different industrial sectors, and the thermal use and the recovery of valuable compounds of the byproduct gases may be conducted to improve the energy efficiency of the steelmaking process with subsequent reduction of CO 2 emissions. BOF gas is one of the important byproduct energies in the steelmaking process, which has nearly 34% of the abandoning rate in China's steel companies.…”

It is inevitable to encounter increase in slag thickness, foaming slag, and high iron loss due to excessive formation of titanium carbonitride in blast furnace smelting of full high Cr‐bearing vanadia–titania magnetite (HCVTM). The effects of softening–smelting–dripping properties, the content variation of titanium carbonitride, and mineral element migration process of full HCVTM pellets with abandoned BOF gas (ABOFG) blowing are studied using X‐ray diffraction (XRD), X‐ray fluorescent (XRF), inductively coupled plasma‐atomic emission spectroscopy (ICP‐AES), X‐ray photoelectron spectroscopy (XPS), electron probe microanalysis‐wavelength‐dispersive spectrometer (EPMA‐WDS), and scanning electron microscope‐energy dispersive spectroscopy (SEM‐EDS). ABOFG is a type of neglected byproduct gas resource produced in the steelmaking process with high physical and chemical thermal energies and contains 20–40% CO, 20–30% CO2, 2–5% O2, and 30–50% N2. As the concentration of CO2 in ABOFG increases, the position and height of the cohesive zone decline, and the concentration of titanium carbonitride decreases from 1.424% to 1.035%, which are beneficial to the BF smelting process. In addition, the migration processes of Ti, V, and Cr are also affected, especially Ti tends to enrich in the dripped slag, whereas V and Cr tend to concentrate at the dripped iron.
