Abstract: Various techniques are provided in relation to flocculation and/or dewatering of thick fine tailings, with shear conditioning of flocculated tailings material in accordance with a pre-determined shearing parameter, such as the Camp Number. One example method of treating thick fine tailings including dispersing a flocculant into the thick fine tailings to form a flocculating mixture; shearing the flocculating mixture to increase yield stress and produce a flocculated mixture; shear conditioning the flocculated mixture to decrease the yield stress and break down flocs, the shear conditioning being performed in accordance with the pre-determined shearing parameter to produce conditioned flocculated material within a water release zone where release water separates from the conditioned flocculated material. The conditioned flocculated material can then be subjected to dewatering, for example by depositing, thickening or filtering. The design, construction and/or operation of a flocculation pipeline assembly can be facilitated.

Abstract: A method for controlling insect pests on a plant is provided. The method includes applying to the plant and/or to the insect pests a combination comprising: a nitrogen-bearing macrocyclic compound which is a photosensitizer that generates reactive oxygen species in the presence of light, the photosensitizer being selected from the group consisting of a porphyrin, a reduced porphyrin and a mixture thereof; and a chelating agent which is an aminopolycarboxylic acid compound or an agriculturally acceptable salt thereof; and exposing the plant to light in the presence of the insect pests to activate the nitrogen-bearing macrocyclic compound and generate reactive oxygen species.

Abstract: Implementations of the present disclosure relate to a method of operating a coker unit comprising the steps of: collecting a coker-furnace feed stream; introducing the coker-furnace feed-stream into a coker furnace for producing a coker-drum feed stream; and introducing a hydrogen-donor gas into either or both of the coker-furnace feed stream or the coker-drum feed stream.

Abstract: A process for the treatment of thick fine tailings that include constituents of concern (CoCs) and suspended solids is provided. The process includes subjecting the thick fine tailings to treatments including chemical immobilization of the CoCs, polymer flocculation of the suspended solids, and dewatering. The chemical immobilization can include the addition of compounds enabling the insolubilization of the CoCs. Subjecting the thick fine tailings to chemical immobilization and polymer flocculation can facilitate production of a reclamation-ready material, which can enable disposing of the material as part of a permanent aquatic storage structure (PASS).

Abstract: A method is provided for the treatment of waste streams resulting from the processing of hydrocarbons that contain naphthenic acids, for example desalter brine resulting from the extraction or production of hydrocarbons from an oil sands reservoir. Naphthenic acids can be removed from these streams by removing oil-wet solids from the waste stream prior to conventional waste water processing, and the oil-wet solids can further be independently remediated to reduce naphthenic acid concentration for disposal.

Abstract: An integrated process that is operated to create both a higher value pipelineable crude and a higher value carbon fiber product from a lower value common heavy hydrocarbon feedstock where the feedstock is processed in a thermal reactor followed by a solvent deasphalting unit with the liquids being gathered and processed to reduce olefins for pipeline transport and the solids are processed to generate a marketable carbon fiber product with any gases generated throughout the entire process reused in the process or sold.

Abstract: Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.

Abstract: Implementations of the present disclosure relate to an apparatus and a method for reducing a selenium-content of a fluid-input stream. The present disclosure includes components and steps for performing chemical modifications of a fluid-input stream and further components and steps for performing physical modifications of a chemically-manipulated fluid stream. When the fluid-input stream has a selenium content the chemical modification of the fluid-input stream drives at least a portion of the selenium content into a selenium-containing solids phase. The chemical modifications include at least oxidation, coagulation, chelation and flocculation. The present disclosure also includes components and steps for performing physical modifications that separate and remove some or all of the selenium-containing solids phase from the liquid phase, which reduces the selenium content of the liquid phase.
