Abstract:
A process for drying fine tailings is provided. The process, which may use a pipeline reactor system, comprises providing an in-line flow of the fine tailings; continuously introducing a flocculent solution to cause dispersion and commence flocculation of the fine tailings and may comprise rapid turbulent mixing; subjecting the fine tailings to flocculation and water release conditioning in-line to cause formation and rearrangement of floes and increasing the yield shear stress to form flocculated fine tailings while avoiding over-shearing of the flocs; and depositing the fine tailings to allow the release of water, formation of a non-flowing fine tailings deposit and drying of the non-flowing fine tailings deposit. The process enables effective in-line dispersion, flocculation and water release, resulting in reliable deposition and drying of the fine tailings deposit.
Abstract:
An herbicide composition available as a concentrate for dilution with water or a ready-to-use oil-in-water emulsion which has a significantly reduced amount of active ingredient of a broadleaf herbicide. The composition combines the reduced amount of herbicide in a mixture of oil and emulsifier.
Abstract:
Fungicidal compositions comprising a paraffinic oil and 2-chloro-N-(4′-chloro[1,1′-biphenyl]-2-yl)-3-pyridinecarboxamide (boscalid) are provided. The fungicidal compositions may further comprise a pigment. The fungicidal compositions may be provided as oil-in-water (O/W) emulsions which may be used for controlling fungal disease, such as dollar spot or bentgrass dead spot or bermudagrass dead spot, in plants, such as turfgrasses. Methods of applying the fungicidal compositions are also provided.
Abstract:
A paraffinic spray oil and a method of using the spray oil for controlling turfgrass pests is disclosed. The spray oil comprises paraffinic oil and a quick break emulsifier, which is formulated as an oil-in-water (O/W) emulsion for use. The paraffinic oil and emulsifier are present in a weight ratio ranging from about 95:5 to about 99.95:0.05, and preferably from about 98.5:1.5 to about 99.9:0.1. When applied to turfgrass, the O/W emulsion quickly releases the oil phase upon application to the turfgrass to contact pests thereon. When provided at sufficient paraffinic oil dosages, generally at least about 0.5 gal oil/acre and preferably in the range of about 0.5 gal/acre to about 60 gal/acre, the spray oil is effective in controlling a variety of turfgrass pests, particularly insect and fungal pests, with little or no phytotoxic effects. Further, use of the spray oil as indicated for controlling turfgrass pests also enhances the growth of turfgrass.
Abstract:
In various aspects, the invention provides for processing a hydrocarbon feed having hydrocarbon and emulsified aqueous components demulsifying into hydrocarbon and aqueous phases over an initial demulsification time, with an active agent to form a treated feed. The active agent has an active agent solubility in the hydrocarbon component and in the aqueous component, the aqueous component has an aqueous component solubility in the hydrocarbon component. The active agent solubility in the hydrocarbon component is greater than the aqueous component solubility in the hydrocarbon component. The active agent solubility in the aqueous component is greater than the active agent solubility in the hydrocarbon component. The active agent solubility in the aqueous component is greater than the active agent solubility in the hydrocarbon component. A treated demulsified hydrocarbon phase separates from the active agent and the aqueous component in a modified demulsification time that is shorter than the initial demulsification time.
Abstract:
This disclosure features a method for promoting the health of a plant (controlling diseases caused by fungal infection) which comprises applying a composition comprising a paraffinic oil to the root tissue of the plant. The composition also comprises an emulsifier and optionally a pigment, a silicone surfactant, an anti-settling agent as well as a conventional chemical fungicide.
Abstract:
An apparatus and a method for operating a process line for processing mined oil sand ore into a bitumen-containing slurry. The method may include: collecting, at least at one location, a plurality of measurements from one or more sensors; computing at a central controller a calculated value based on at least one of the plurality of measurements; and, applying an adjustment to an operating variable of a component of the process line to override a target set-point of a regulatory controller for that component based on the calculated value and a target value for the calculated value. The method and apparatus may receive measurement values in at least one step, and apply a correction to future measurement values in another step.
Abstract:
A drilling fluid is provided which results in an enhanced rate of penetration, and more particularly, a drilling mud composition is provided with a reduced ester content which maintains an enhanced rate of penetration.

Abstract:
A system for wireless process control comprises at least a first wireless network, which is used to communicate real-time instructions and data between one or more pieces of mobile equipment to at least one other piece of mobile equipment. In one variant, a second wireless network is provided, using a different radio frequency band, to concurrently communicate the same or substantially the same real-time instructions and data as are communicated over the first wireless network.
