The Bio Steel Cycle: 7 Steps to Net-Zero CO2 Emissions Steel Production

Optimization of Syngas Production Systems Subject to Almost Net-Zero CO2 Emissions

This work describes two different configurations of syngas production processes using a combination of steam methane reforming (SMR) and dry reforming of methane (DRM). The ideal SMR+DRM process ensures the maximum product yield, the heat-integrated SMR+DRM process fulfills the maximum heat recovery, and the stand-alone SMR+DRM process effectively suppress net CO2 emissions. Through kinetic mod...

Towards zero CO2 emissions in the production of methanol from switchgrass. CO2 to methanol

In this work an integrated facility is proposed that produces methanol from switchgrass and uses the captured CO2 to enhance the production capacity by 50% via CO2 hydrogenation. The process consists of two sections, biomass processing to syngas and its conversion to methanol, and the electrolytic section where hydrogen is produced to hydrogenate the CO2 that has been captured during syngas cle...

Life cycle assessment of steel production from iron scrap: a case study at a steel plant

Background and Objective: The steel industry is the world's largest consumer of energy. A large amount of iron waste is produced annually, which its use in the steel industry can be economic. The purpose of this study was to investigate the environmental impacts of the steelmaking from iron scrap as a raw material using a life cycle assessment (LCA) method. Materials and Methods: Simapro softw...

Effects on global CO2 emissions when substituting LPG with bio-SNG as fuel in steel industry reheating furnaces: The impact of different perspectives on CO2 assessment

The iron and steel industry is the second largest user of energy in the world industrial sector and is currently highly dependent on fossil fuels and electricity. Substituting fossil fuels with renewable energy in the iron and steel industry would make an important contribution to the efforts to reduce emissions of CO2. However, different approaches to assessing CO2 emissions from biomass and e...
