Simulation and multi-objective optimization of liquid hydrocarbons production by coupling Blast Furnace Gas with Coke Oven Gas of steelwork

Hamid Javan-Bari et al.

Summary: In this paper, the recovery of blast furnace gas and coke oven gas is simulated using Aspen HYSYS. By mixing a portion of these gases and injecting into the Fischer-Tropsch reactor, liquid hydrocarbons can be produced. The optimized simulation results show that this process can provide syngas without fuel consumption and significantly reduce CO2 emissions.

Enhancing the production of liquid hydrocarbons by coupling blast furnace gas (BFG) of steelwork with syngas in the GTL process

Rasul Karamlu et al.

Summary: Steelwork is a major contributor to global CO2 emissions. Efforts are being made to mitigate these emissions through unit optimization, carbon capture and storage (CCS), and utilization (CCU). This study focuses on utilizing blast furnace gas (BFG) to improve the efficiency of the gas-to-liquid (GTL) process and reduce CO2 emissions.

Solid waste biomass as a potential feedstock for producing sustainable aviation fuel: A systematic review

Elissavet Emmanouilidou et al.

Summary: The aviation industry contributes 2% of anthropogenic greenhouse gas emissions and sustainable aviation fuels are essential for reducing these emissions. This study investigates the potential of producing sustainable aviation fuel from waste materials using current conversion technologies. The results suggest that catalytic hydro-processing of waste lipid feedstocks is the most commonly used method for bio-jet fuel production. Gasification combined with Fischer-Tropsch and alcohol-to-jet processes show promise for sustainable aviation fuel production. However, further research and development are needed before these technologies can be commercialized.

CO2 utilization for the production of liquid hydrocarbons by coupled steam and dry reforming of bioethanol

Milad Ahmadi et al.

Summary: This study simulates the production of liquid hydrocarbons as synthetic fuels using bioethanol reforming and proposes two different processes. The results show that the H-2/CO ratio of the syngas produced from ESR is 5, and it is modified to 2.5 and 2 in ESR+EDR, which is suitable for the production of liquid hydrocarbons in the gasoline range.

Investigation of steam and CO2 gasification for biochar using a circulating fluidized bed gasifier model in Aspen HYSYS

Furkan Kartal et al.

Summary: Researchers are focusing on renewable energy sources, and biomass gasification and biochar gasification are effective ways to overcome the drawbacks of biomass in gasification operations. However, there is limited research on biochar gasification, especially in the context of Aspen HYSYS simulator. This study developed a unique CFB gasifier model and evaluated the impacts of various operating parameters on syngas.
