Herein, optimal configuration and microgrid's energy control based on day-ahead planning is proposed. For this purpose, fossil fuel resources are equipped with carbon capture utilization and storage (CCUS) technologies, and INVELOX turbines are proposed in microgrid's planning. The microgrid's overall contamination and cost are considered as objective functions. To encourage the consumers to utilize renewable resources, obtained profit from CCUS is assigned as incentive programs for buying their extra energy. Also, the problem is modeled as a mixed-integer linear programming (MILP), and the epsilon constraint and fuzzy satisfying approach are utilized to tackle and accomplish the best and optimal solution. The outcomes show that overall costs and contamination are

Deriving Economic Potential and GHG Emissions of Steel Mill Gas for Chemical Industry

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.

“…CO 2 methanation was first studied at the beginning of the last century to remove carbon oxides traces, and it has gained renewed interest in relation to the power-tosubstitute natural gas (SNG) technology. [17][18][19] Due to the high exothermicity of the reaction (ΔH 298K = −167 kJ/ mol) some implementation challenges are still to be solved.…”

“…CO 2 methanation has been investigated by several authors, both in terms of kinetics [17] and technoeconomic assessment. [18][19][20] A thorough life-cycle assessment has been carried out by Sternberg et al, [6] who compared CO 2 -based C1 chemicals production processes based on global warming reduction and fossil depletion impacts. However, to the best of our knowledge, a comprehensive comparison of the different pathways from a technological standpoint is still missing, which would be useful to identify the strengths, as well as drawbacks or possible bottlenecks of these syntheses with a focus on mass and energy-related aspects.…”

Carbon dioxide (CO2) conversion by catalytic reaction with hydrogen to produce different C1 chemicals is a promising strategy in view of the development of a sustainable chemical industry. In this work, two CO2 hydrogenation routes are investigated in detail, respectively syngas and formic acid syntheses. Starting from published experimental reaction data, simulation models based on a kinetic analysis were developed and implemented in Aspen Plus process simulator. The two processes are analyzed according to a number of selected technological indicators, comprising CO2 conversion, specific H2 consumption, product yield, energy duties, and carbon emissions. To extend our study, three additional CO2 conversion pathways are considered, respectively methanol, methane, and urea syntheses, whose technological performances were retrieved from similar studies available in the scientific literature. Under the assumption that H2 is available from renewable sources, our results highlight that CO2 conversion routes towards fuel compounds (ie, syngas and methane) look particularly appealing from the energy balance point of view. If non‐renewable energy is used to produce H2, the actual environmental benefits (in terms of net CO2 emissions) strongly depend on the country‐specific carbon intensity for electricity generation.
