Title: The Innovations of Frederick C. Stuchberry
Introduction
Frederick C. Stuchberry is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of bitumen recovery, particularly in the extraction processes from tar sands. With a total of 3 patents to his name, Stuchberry's work has had a lasting impact on the oil industry.
Latest Patents
Stuchberry's latest patents include a process for the recovery of bitumen from a bituminous froth. This improved method is particularly applicable in the hot water separation of tar sands. The process involves slurrying comminuted tar sand in hot water, followed by gravity separation to isolate a bituminous froth. This froth, which contains water and mineral matter, is then diluted with a liquid hydrocarbon solvent and subjected to a two-stage centrifugation to recover substantially water and mineral-free bitumen. In this improved process, the dilution of bituminous froth with liquid hydrocarbon solvent is staged to ensure that no more than about 90% of the total hydrocarbon solvent is added prior to the first centrifuging stage.
Another significant patent is the design of a tar sands conditioning drum. This rotating drum type muller is used for the initial conditioning of mined tar sands by the hot water method for separation of bitumen. The drum facilitates the ablation of mined tar sand lumps into pulp through the addition of hot water, steam, and caustic. The design includes a horizontally disposed cylindrical drum with axial openings for the introduction of materials and a grated peripheral opening for the discharge of tar sand pulp.
