Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

First Operation Results of a Methanol Demonstration Plant With Real Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.A demonstration plant with industrial setup regarding length, diameter, boiling water cooling system and gas recycle was initially operated with cleaned blast furnace gas and compared with earlier experiments with bottle gases. Dynamic disturbances from the steel mill and gas cleaning unit were noticed and could be compensated by the control system ...

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry
Chemie Ingenieur Technik, EarlyView.The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Comparative Assessment of Methanol Production Pathways From Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.This publication reviews the process concepts and assessments for converting steel mill gases into sustainable methanol, focusing on energy efficiency, and the regulatory framework. From an energy perspective, the production of methanol from BOFG and H2 separated from coke oven gas is of particular interest.
