“…The (NORDICCS, 2017) project has evaluated the potential of using waste heat from cement industry to cover the reboiler duty of the stripper for an aminebased CO2 capture plant and concluded that utilisation of waste heat is necessary in order to lower the cost of CO2 capture. The CO2stCap project (Skagestad et al, 2017) is in progress in Norway and Sweden to evaluate different possibilities for partial CO2 capture from industrial sources.…”

In order to remove CO2 from power or process industry, a well-known method is absorption in monoethanolamine (MEA) followed by desorption, and this technology has been in operation for decades. The major challenge is the high energy demand for CO2 desorption. In many industrial cases, a limited amount of cheap waste heat is available and this makes partial CO2 capture an interesting option. It is not obvious whether a high removal efficiency from a part of the exhaust or a low removal efficiency from the total exhaust is the optimum solution. In this work, simulations of traditional amine-based CO2 capture processes are performed with full-flow and part-flow of flue gas. The cost of CO2 capture is estimated using a detailed factor method and a Lang factor method. It is found that a full-flow alternative is the energy optimum while a part-flow alternative treating 80% of the exhaust gas is the cost optimum. This work shows that the calculated optimum is dependent both on the criteria used and on the selected method.

“…CCS can be applied to either the silicon and aluminum processes, but in many ways the silicon process is better suited as the concentration of CO 2 in the flue gas around 3-4% [24,25]. This is at the low end for existing carbon capture solutions, so further up-concentration would make this stream more feasible for carbon capture.…”

The world now pushes for a low-carbon future, and international goals for greenhouse gas emission reductions have been set. Industrial processes, including metallurgical processes, make up more than a fifth of the total global emissions, and those have been rising with infrastructure development and the expansion of the middle-class worldwide. This paper focuses on two energy-intensive processes, aluminum production and metallurgical grade silicon production, and how the carbon footprints from these industrial processes have developed in recent decades. The main trend is that the increased demand for these metals has led to expanding primary production for both of them, based on energy with an increasing share of fossil-based electric power. In fact, the average carbon footprint of the energy used in aluminum and silicon production has increased by 38% and 43%, respectively, from 2000 to 2019. The change in energy mix offsets any progress in process efficiencies. This work addresses this and discusses opportunities for improvements. Graphical Abstract

“…The pulp and paper industry is an energy-intensive sector with most of the CO 2 emissions arising from the combustion of biomass onsite . Coupling the pulp and paper production process with CCS could have the potential to provide net removal of atmospheric CO 2 , that is, negative emissions as a bioenergy with CCS (BECCS) technology. , Studies indicate that post-combustion capture of CO 2 from the recovery boiler, and bark boiler flue gases offer the greatest CO 2 reduction potential. − The recovery boiler accounts for as much as 70–80% of the emissions for a pulp mill . Absorption-based CO 2 capture is often considered due to the low CO 2 concentration of 12–13% mol in the flue gases from the recovery boilers, ,, which is similar to coal flue gas (12–14 % mol CO 2 ).…”

As more countries commit to a net-zero GHG emission target, we need a whole energy and industrial system approach to decarbonization rather than focus on individual emitters. This paper presents a techno-economic analysis of monoethanolamine-based post-combustion capture to explore opportunities over a diverse range of power and industrial applications. The following ranges were investigated: feed gas flow rate between 1–1000 kg ·s–1, gas CO2 concentrations of 2–42%mol, capture rates of 70–99%, and interest rates of 2–20%. The economies of scale are evident when the flue gas flow rate is <20 kg ·s–1 and gas concentration is below 20%mol CO2. In most cases, increasing the capture rate from 90 to 95% has a negligible impact on capture cost, thereby reducing CO2 emissions at virtually no additional cost. The majority of the investigated space has an operating cost fraction above 50%. In these instances, reducing the cost of capital (i.e., interest rate) has a minor impact on the capture cost. Instead, it would be more beneficial to reduce steam requirements. We also provide a surrogate model which can evaluate capture cost from inputs of the gas flow rate, CO2 composition, capture rate, interest rate, steam cost, and electricity cost.
