This study describes the evaluation of the mixed metal non-supported and supported ion exchanged sorbents for hot gas desulfurization capable of withstanding a wide temperature range and multiple sulfidation-regeneration cycles. Copper-cobalt, copper-cerium mixed metal oxide and mixed metal oxide...

Bitumen froth is an intermediate product of bitumen upgrading which must be treated to remove solids and water. De-mineralization and de-watering occur through a settling operation in which the addition of a diluent and a demulsifier are crucial to its success. This work explores the effect of...

Chong, Jeng Yi

The impact of mixing on water removal from diluted bitumen and bitumen froth is studied, with the goal of maximizing demulsifier performance. The relative effects of bulk concentration, mixing intensity, mixing time and injection concentration on the demulsifier performance are evaluated. A...
