Abstract: Techniques for dewatering thick fine tailings may include one or more pre-treatment steps, such as pre-shearing to reduce the yield stress prior to flocculation, hydrocarbon removal below a threshold to improve flocculation and dewatering, flocculant dosing on a clay basis, and providing certain properties of the thick fine tailings related to coarse and fine particle sizes and/or chemistry such as divalent cation content. Various advantages may result from pre-treatments based on thick fine tailings properties, such as reduced flocculant dosage requirements, improved dispersion of flocculant into the thick fine tailings and/or enhanced dewatering, for example. One or more of the pre-treatments may be performed.

Abstract: There is provided a method for inhibiting growth of a microbial pathogen of a plant. The method includes applying to the plant a combination including a nitrogen-bearing macrocyclic compound which is a singlet oxygen photosensitizer selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and a chelating agent to increase permeability of the microbial pathogen to the nitrogen-bearing macrocyclic compound; and exposing the plant to light to activate the nitrogen-bearing macrocyclic compound and generate reactive singlet oxygen species.

Abstract: A method and apparatus for analyzing a bitumen-containing process stream and controlling a process. The method including directing a beam of infrared light at the bitumen-containing process stream, capturing light corresponding to the infrared light after interaction with the bitumen-containing process stream, and analyzing the captured light to obtain a spectrum. A composition estimate can be generated based on the spectrum and a calibrated model. A controller is operative to adjust a setpoint of the process in response to the composition estimate.

Abstract: Implementations of the present disclosure relate to a blind flange and a method of installing same for isolating hazardous energy in order to provide a safe environment for workers to conduct maintenance or repair work on a facility. The blind flange has a body that defines one or more modified bores. The one or more modified bores are alignable with flanged-connection apertures of one side of a flanged connection. The one or more modified bores are configured to receive and releasably hold a connection member therein, so as to connect to only one side of the flanged connection. The modified bores allow a blind flanged-connection to be disassembled and reassemble in less time than known blind flanged-connections when one side of the blind flanged-connection is disconnected from the blind flanged-connection. Furthermore, the blind flange of the present disclosure allows the blind flange to remain connected to one side of a flanged connection while the other side is disconnected.

Abstract: A process for operating a thermal or catalytic cracking unit is described, The process entails generating a product that includes cracked hydrocarbon vapor and solid coke-particles from a heavy hydrocarbon input. The product is communicated towards a fractionator and a quench liquid is introduced into the product for creating a two-phase flow of cracked hydrocarbon vapor and the quench liquid with solid coke-particles entrained in the quench liquid. The two-phase flow is introduced into the fractionator and the cracked hydrocarbon vapor are separated from the quench liquid and the solid coke-particles entrained therein by gravity separation. The two-phase flow can reduce or remove the requirement of a wash zone within the fractionator. A recirculation loop is included in a wash-zone circulation system. The recirculation loop bypasses one or more spray headers of the wash zone and returns to a first end of the wash-zone circulation system.

Abstract: Apparatus is provided featuring a signal processor or processing module configured at least to: a signal processor configured to: receive signaling containing information about at least one rheological parameter related to a fluid containing Mature Fine Tailings (MFTs) flowing through a process pipe; and determine a dosing of a polymer to the fluid so as to cause a polymer induced agglomeration of the MFTs in the fluid, based at least partly on the signaling received. The signal processor may be configured to provide corresponding signaling to control the dosing of the polymer to cause the polymer induced fine agglomeration of the MFTs in the fluid.

Abstract: Provided is a system for transporting an oil sand slurry, comprising a pump, upstream and downstream lines, a shaft connectable to the pump, a driving mechanism driving the pump and a regulator for regulating the torque applied to the shaft between positive and negative torque modes, to pump the slurry at higher or lower flow rates. Also provided is a method comprising pumping the slurry through a pipeline using a pump driven by a motorized shaft and adjusting the flow rate of the slurry by varying the torque applied to the motorized shaft between positive and negative torque modes. The oil sand slurry transportation system and method enable positive head (regular pump action) for normal and high flow rates and negative head (pump brake action) for low flow rates, which reduces system energy loss, pipeline wear, vapor breakout and sanding off.

Abstract: A system and method are provided for recovering bitumen from a bitumen reserve. The method includes recovering bitumen from an alternative pay region in the bitumen reserve via gravity drainage using an inclined horizontally drilled well drilled from a drainage pit upwardly into the bitumen reserve. The drainage pit has been excavated into an area of an underlying formation that is, at least in part, adjacent to and underlying the bitumen reserve. The alternative pay region includes a region unsuitable for recovering bitumen by surface mining or by in situ recovery using wells that produce bitumen to ground level above the alternative pay region.

Abstract: A method of increasing a dwell time of a slurry facility at a given ore processing location by using a mobile oil sands mining system. The method involves coordinating the operation of at least two mining conveyors to facilitate mining at least one arc-shaped sector of ore that otherwise would not be within operational reach of the slurry facility at the ore processing location. The method increases the slurry facility's operational time at the ore processing location before relocation thereof is required to keep the slurry facility within operational reach of at least one receding mine face.
