Oil sands treatment system and process
Oil sands ore containing bitumen is treated in a reactor chamber by ultrasonic oscillations impact such that cavitation of ore molecules occurs. The disintegration of the pulsating bubbles in the cavitation results in the separation of the oil, water, sand and air fractions of the oil sands. The oil fraction may be continuously extracted for subsequent refining processes.
1. A system of treatment of oil sands ore comprising,
a receiver bunker operative for mixing said oil sands ore in a crushed state with a predetermined amount of water to form a pulp mixture,
a reactor chamber having an inlet port connected to said receiver bunker,
a vortex jet located at said inlet port and operative to inject said pulp mixture in a spray form into an active zone in said reactor chamber,
ultrasonic oscillations transducers located in said active zone in said reactor chamber, said ultrasonic oscillations transducers emitting two ultrasonic oscillation frequencies interfering with one another to produce intense concentrated resonant ultrasonic oscillations to impact on molecules of said spray form of pulp mixture in said active zone for causing cavitation to occur in said molecules of said pulp mixture in said spray form for separating oil, water and sand fractions of said pulp mixture,
a separation tower connected to said reactor chamber and operative for separating oil fraction of said pulp mixture after having subjected to cavitation in said reactor chamber.
2. A system of treatment of oil sands according to claim 1 including mechanically operative blenders located in said reactor chamber, said blenders being operative for passing said pulp mixture a plurality of times repeatedly through said active zone of said reactor chamber.
3. A system of treatment of oil sands ore according to claim 2 wherein said resonant ultrasonic oscillations impose an intense impact of an ultrasonic field energy density of more than 40 to 60 W/cm 2 on said pulp mixture.
4. A system of treatment of oil sands according to claim 3 including a collection tank connected to said separation tower and operative for receiving said oil fraction from said separation tower for subsequent refining process.
5. A system of treatment of oil sands according to claim 4 including a water tank connected to a lower portion of said separation tower and operative for receiving a water fraction from said pulp mixture in said separation tower.
6. A system of treatment of oil sands according to claim 5 including a conveyor connected to a bottom part of said separation tower and operative for receiving and conveying sand and solid fractions of said pulp mixture from said separation tower.
