SUMMARY:Decarbonization in iron & steel industry: Advanced flue gas cleaning, CO2 separation and waste heat recovery
DESCRIPTION:With the goal of reducing greenhouse gases to prevent global warming above 2 °C, industry is facing an unprecedented challenge. In this context, the reduction of CO2, as the main driver of global warming, represents a sensible and sustainable solution from many points of view. On the one hand, there is increasing national and international pressure regarding energy and CO2 saving solutions. On the other hand, there is also an opportunity to reduce operating costs in long term by a new sustainable orientation. Particularly in the context of sharply rising certificate costs for CO2, a trend is emerging that a decisive step must be taken in the direction of sustainable and ecological industrial processes.

The iron & steel industry is well aware of these issues; many plants have already taken the first step to energy and decarbonization optimization. A much-discussed approach is to substitute coke or natural gas with hydrogen, preferably produced climate-neutral, for the reduction of iron ore. 

Despite these process optimizations, the direct emission of CO2 should still be avoided. Chemical absorption by means of amine solution has become established as a commercially proven downstream solution. The absorption process requires a very low content of residual impurities in the off gas, which can be ensured by using advanced gas cleaning technologies.

In addition to indirect CO2 reduction, direct heat recovery from the energy-rich process is particularly well suited here for solvent regeneration, whereby surpluses can still be used to cover the company's own electricity consumption and / or compressed air generation. 

In this context, an overview of the sustainability goals described above is given to focus on the expanded importance of emission control.
