Role of Caustic Addition in Bitumen-Clay Interactions [PDF]

open access: yes, 2015
Coating of bitumen by clays, known as slime coating, is detrimental to bitumen recovery from oil sands using the warm slurry extn. process. Sodium hydroxide (caustic) is added to the extn.

Combustion of Coal and Coal Slime in Steam-Air Environment and in Slurry Form

open access: yesEnergies, 2022
One of the ways to minimize anthropogenic emissions from coal combustion is to replace conventional schemes used for the introduction of coal dust into the furnaces of power plants through the injection of water-containing fuels. In this research, the three most promising schemes for fuel combustion were implemented: (i) the simultaneous introduction ...

(Re)Pairing With Water: Climate Finance and the Prefigurative Positions of an Ocean Counter‐Politics

open access: yesAntipode, Volume 58, Issue 2, March 2026.
ABSTRACT This paper takes up recent calls to work ‘for and against climate capitalism’ to foreground the possibility of strategic engagements within capitalist structures that could destabilise its long‐standing exploitative dynamics. In doing so, it locates prefigurative positions of an ocean counter‐politics generated through novel blue financial ...
