Latest Patents

Stevens holds a patent for a "Static deaeration conditioner for processing of bitumen froth." This invention discloses an apparatus and method designed to deaerate and condition bitumen froth obtained from a primary tar sands bitumen extraction process. The apparatus comprises a vessel containing a plurality of inclined plates, known as a static deaeration conditioner. These plates are substantially equidistantly spaced and inclined at an angle to the horizontal, forming multiple channels for the froth to flow through. The design promotes a gravity-induced froth flow rate that exhibits lamella effect characteristics, enhancing the creation of a water-enriched froth region near the lower plate of the channel. Additionally, a braking pump can be utilized at the outlet port of the vessel to control the flow rate of the froth being processed.
