Human health risk characterization of petroleum coke calcining facility emissions

Regulatory Toxicology and Pharmacology, 2015
Calcining processes including handling and storage of raw petroleum coke may result in Particulate Matter (PM) and gaseous emissions. Concerns have been raised over the potential association between particulate and aerosol pollution and adverse respiratory health effects including decrements in lung function.

Effect of the additive concentration on the modification of petroleum coke and anode quality

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Calcined petroleum coke is one of the major raw materials for anode manufacturing, which is used as the carbon source in electrolytic cells for primary aluminium production. It constitutes around 65%–70% of the anode recipe. Therefore, the quality of calcined coke has an important impact on anode quality, which affects the cost, energy ...

Transient thermal modelling of green anode cooling in the aluminium industry

The Canadian Journal of Chemical Engineering, EarlyView.
Summary of the methodology. Abstract Anodes, which are used in electrolytic aluminium production, are made by mixing dry aggregate (petroleum coke, rejected anodes, and butts) with coal tar pitch, compacting the resulting paste (green anode), and baking (baked anode). After compaction, the anodes are cooled to maintain their structural integrity before
