Beyond the Reports: Cultural Pressures, Unheard Voices and the Climate Accountability Gap in Oil and Gas Sector Governance

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental governance in Nigeria's oil and gas sector remains central to global climate justice debates, yet persistent accountability failures continue to undermine meaningful environmental and social outcomes. Despite extensive regulatory frameworks, accountability in resource‐dependent contexts is frequently reduced to formal reporting ...

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 ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...
