Title: Antony H Leung: Innovator and Patent Holder

Introduction:

Antony H Leung is an esteemed innovator and patent holder based in Sherwood Park, CA. With an impressive portfolio of three patents, Leung has made significant contributions to the field of oil-sand extraction and separation processes. Through his ingenious inventions, he has enhanced the efficiency and effectiveness of the hot water process for extracting bitumen from mined oil sand.

Latest Patents:

One of Leung's latest patents is the "Pipeline Conditioning Process for Mined Oil-Sand." This unique process involves mixing as-mined, naturally water-wet oil sand with hot water and NaOH to create a slurry containing entrained air. By pumping this slurry through a pipeline of considerable length, coalescence and aeration of bitumen occur. When subsequently brought to a gravity separation vessel, a viable amount of bitumen floats and forms froth, which can be recovered efficiently.

Another remarkable innovation by Antony H Leung is the "Microbubble Flotation Process for the Separation of Bitumen from an Oil." This improvement to the existing hot water process involves producing microbubbles of air. These microbubbles, with diameters less than about 100 microns, are injected into the diluted aqueous tar sand slurry after the conditioning step and prior to the slurry's introduction into the flotation/settling step. This method significantly enhances bitumen recovery, further optimizing the extraction process.

Career Highlights:

Throughout his career, Antony H Leung has worked with prominent companies in the energy sector.
