摘要:
Equipment and a process for separating bitumen from oil sand in a process stream are described. The equipment includes several processing vessels and one or more local area radio frequency applicators to selectively heat the process stream in local areas of the equipment. The local area can be adjacent to an input or output of a component of the equipment. Also described is equipment for processing an oil sand—water slurry, including a slurrying vessel, a slurry pipe, and a local area radio frequency applicator. The local area radio frequency applicator is located outside of the slurry pipe, and heats the local area without significantly heating the contents of the slurrying vessel or of the downstream portion of the slurry pipe.

A method of determining a permittivity of a substance may include providing a probe having a planar end surface, providing a signal source and a signal receiver coupled to the probe, and physically contacting the substance with the planar end surface of the probe defining an interface. The method may further include measuring a reflection coefficient of the substance by at least transmitting a signal through the probe to the interface, receiving a reflected signal from the interface, and comparing the transmitted and reflected signals. The method may further include calculating the permittivity of the substance based upon the reflection coefficient.

An aspect of the invention concerns a method of determining the permittivity of a substance using a probe having known dielectric characteristics, a planar end surface normal to the axis of the probe, a signal source, and a signal receiver. In this aspect, the method is carried out by contacting the substance with the planar end surface of said probe to form an interface between the probe and the substance. The method further involves measuring the reflection coefficient of the substance by (1) transmitting a signal through the probe to the interface, (2) receiving the signal reflected from the interface, and (3) comparing said transmitted and reflected signals, and then calculating the permittivity of said substance from the reflection coefficient as so measured. Another aspect of the invention concerns a method of heating a substance, such as bituminous froth, by determining the permittivity of a substance, and providing a radiation source physically and electrically spaced from the substance, with the radiation source having an impedance approximating the complex conjugate impedance of the substance.

A device for processing a hydrocarbon resource may include a radio frequency (RF) source, a first RF conductor, a second RF conductor, and a hybrid coupler assembly coupled to the RF source and the first and second RF conductors. The first and second RF conductors may each having distal ends configured to receive the hydrocarbon resource therebetween and apply RF power from the RF source to the hydrocarbon resource.
摘要:
High power RF energy supplied to a reaction chamber at a resonant frequency is used to break the covalent bonds of a hydrocarbon material without heat. An RF signal generator may be used to supply RF energy to a resonant ring through a four port coupler. The phase of the RF energy passing through the resonant ring may be adjusted to achieve an integral multiple of a resonant wavelength. Wavelength and intensity may be adjusted to sublimate or pyrolyze the hydrocarbon material to yield a useful gaseous product.

Applicant presents an improved manner of modeling and calculating the tongue-and-groove effect in multi-leaf collimators in treatment planning systems and processes. The method is based on subtracting an individualized profile area that is determined for each individual model of MLC. The method also includes how to easily obtain the shape of this non-constant profile based on the tests. The method provides better accuracy, particularly for plans using small MLC gaps.
