Abstract: The use of recycled materials can have significant economic value. With the increasing quantity of recycled material used in viscoelastic materials, especially asphalt mixture, understanding how they interact with original materials to produce a mixture that performs successfully, becomes critical. Currently, the technology to determine the effect of additives on the performance of asphalt mixture is lacking. The present invention relates to a new unified methodology for mechanical testing of asphalt mixture and other viscoelastic materials that improves the current practice in speed, convenience, and accuracy. A new improved specimen mounting method on Dynamic Shear Rheometer (DSR), a new recovery method for fine portion of asphalt mixture, and three new tests for the performance of recovered material using DSR is disclosed. The new methods provide performance grading of asphalt mixtures that is new to the industry and provide necessary tools for determining the effect of recycled materials on performance.

Abstract: Settling unconverted pitch from a SHC reactor effluent before fractionation improves efficiency of fractionation of slurry hydrocracked products. The recycle of soft pitch to the SHC reactor results in improved reactor operation by avoiding the recycle of lighter products which vaporize in the reactor to occupy reactor space and the recycle of hard pitch which will not convert. The settling step facilitated by mixing with a solvent can achieve a separation between soft pitch and hard pitch not achievable in a fractionation column.

Abstract: Production of bitumen from bitumen froth can include separating the froth into a solvent diluted tailings and solvent diluted bitumen, and then the diluted tailings can be treated to recover solvent for reuse in the froth separation. The solvent recovery from tailings can employ a distributor for use in a tailings solvent recovery unit (TSRU). The distributor can include slot-shaped pressure let-down apertures and a closed curved end portion to introduce the tailings into a separation vessel. The distributor construction can have various advantages, such as facilitating manufacturing as well as effective mitigation of pre-flashing and solids segregation issues, for enhanced bitumen production and solvent recovery operations.

Abstract: An asphalt recovery system may include an extractor, a desolventizer, and an evaporator. During operation, the extractor may receive a solvent and roofing waste and extract asphalt from the roofing waste with the solvent. The desolventizer may receive a solvent-wet solids stream from the extractor and vaporize solvent from the solvent-wet solids stream to yield desolventized solids. The evaporator may receive an asphalt-rich solvent stream from the extractor and vaporize solvent from the stream to produce a solvent stream and an asphalt stream. By configuring the evaporator to operate at a pressure above atmospheric pressure, the boiling point in the evaporator may increase as compared to operating the evaporator at a pressure below atmospheric pressure. In turn, this may keep the viscosity of asphalt within the evaporator less than 500 centipoise, which may improve heat transfer to the asphalt and prevent that asphalt from plugging the evaporator.

Abstract: A method of delivering feed, for example a paraffinic solvent treated bitumen froth, to a separation vessel, for example a froth separation unit (FSU). The feed is delivered from one or more side inlets that may be substantially normal to, and flush with, the wall of the vessel. In contrast to certain conventional feed systems used in gravity separators which use a distributor plate to widely distribute the feed with a vessel, the feed is delivered such that it flows down the inside wall of the vessel. This feed delivery is characterized by a Richardson number of greater than 1.0. Such feed delivery is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The gentle flow serves to mitigate the upward flux of the smaller particles, for example mineral solids, by being trapped below the larger particles, for example precipitated asphaltene aggregates.
