Abrégé

A system and method for treating a feed gas to be subjected to a carbon capture process is provided, having a particulate removal stage configured to receive and remove particulates from the feed gas and output a feed gas substantially free of particulates to be transported to the carbon capture process and a particulate stream for disposal. The system and method can also have a contaminant removal stage for removing contaminants such as sulphur dioxide and other sulphur oxides from the feed gas. Removing the particulates from the feed gas prior to the contaminant removal stage simplifies the feed gas treatment process and results in a reduced footprint, as the used water from the contaminant removal stage dose not require clarification or other processing before being used in other processes or disposed of.

There are provided systems, methods, and processor-readable media for monitoring an electrical submersible pump (ESP) system to classify a type of ESP electrical failure event. According to examples, following the detection of a suspected ESP electrical failure event, a voltage imbalance ratio for the ESP system is computed based on a neutral output voltage (NOV) representative of a voltage imbalance during normal ESP operations and a NOV representative of a voltage imbalance following the suspected ESP electrical failure event. In examples, the voltage imbalance ratio can then be compared to a voltage imbalance threshold value to automatically classify the ESP electrical failure event as a feedthrough failure or an ESP failure. In examples, the automatic classification of the ESP electrical failure event can be incorporated into hydrocarbon production operations to minimize costs and downtime associated with diagnosing the source of the ESP electrical failure.

The present disclosure relates to mitigating intergranular stress corrosion cracking (IGSCC) in ferritic steel pipes and vessels under mineral wool insulation, used applications in oil and gas or other industries, e.g., refining, upgrading, distribution, chemical plants, food processing plants, and other light and heavy industries, where mineral wool is being used, by leveraging the use of an interference material that can be foil or mesh composed, for example, of aluminum. Pipes or vessels composed of bare ferritic steel having residual stresses and where water ingress occurs into the mineral wool insulation and operating between 70 C and 200 C are at higher risk of IGSCC and thus the interference material located in between the ferritic steel and the insulation can help mitigate such challenges.

The technology described herein concerns nozzles configured to expel a liquid in a cone-shaped spray pattern. The nozzles can be used for various purposes, including in a rotary breaker for discharging an aqueous liquid, such as process water, as a sparge nozzle. The use of a cone-shaped nozzle as a sparge nozzle can provide a larger fluid dispersion area, which can lessen the momentum of the expelled fluid and thus the resultant force of the expelled fluid on the interior of the rotary breaker. By providing a larger fluid dispersion area, the nozzles described herein reduce the risk of erosion on the interior surface of the rotary breaker.

Water samples from an in situ recovery operation can be pre-treated using filtration, acidification, extraction, heating and neutralization prior to colourmetric or spectrophotometric analysis to obtain data regarding analytes, such as hardness, that can be used for process control of the in situ recovery operation. For example, in a SAGD surface facility, boiler feed water (BFW) can be sampled and pre-treated to remove interference species. The pre-treated sample is then suitable for colourmetric or spectrophotometric analysis which provides trendable hardness values that can be used to identify upset conditions and react accordingly, such as by adjusting BFW quality.

A solvent based in situ recovery process can have a surface facility for recovering solvent that includes separate process trains for gas and production fluid. Casing gas and other gas streams high in NCG and containing solvent is processed in a first process train that includes a purification tower to produce fuel gas and recovered solvent for reinjection downhole. The production fluid that includes mainly oil, water and solvent is processed in a second process train using flash separation stages to produce an oil product and recovered solvent for reinjection. The production fluid is subjected to degassing prior to flashing and water removal. Mechanical vapour recompression (MVR) may be used to condense a flashed stream and preheat the feed to a flashing stage. The processes can enhance heat use and inhibit NCG contamination of the solvent, which may be a paraffinic solvent such as butane used for bitumen recovery.

A non-aqueous extraction process for producing a bitumen product from an oil sands material that includes an ablation stage is provided. The ablation stage can include adding an ablation solvent to an oil sands material to achieve a solvent-to-ore ratio of less than about 10, mixing the ablation solvent and the oil sands material to reduce the size of the oil sands material and produce ablated ore that includes ablated ore fragments having a diameter of less than about 2 inches, and retrieving the ablated ore as a single stream. The ablated ore can be subjected to a reject separation stage to separate reject material therefrom. The reject material can also be subjected to a wash reject stage. The ablated ore can then be subjected to an extraction stage. Examples of ablators are also described, which can include for instance a conveyor, or can be a rotary screen ablator.

Process implementations for upgrading an asphaltenic feedstock, such as a bitumen feedstock: the asphaltenic feedstock is subjected to solvent deasphalting to produce a deasphalted oil and an asphaltene-rich component, and a feedstream including the asphaltene-rich component is subjected to slurry-phase hydrocracking to produce a gas-liquid mixture. The feedstream can have a resin-to-asphaltenes ratio of at least 1.4. The liquid component of the gas-liquid mixture includes a naphtha fraction, a middle distillates fraction and a gasoil fraction. The naphtha fraction can be hydrotreated to produce a hydrotreated naphtha fraction that is supplied as diluent to the deasphalted oil to form a partially upgraded product that is transportable via pipeline. The gasoil fraction can be recycled into the asphaltene-rich component to form part of the feedstream. The middle distillates fraction can be hydrotreated and recovered as a sweet fraction including diesel for valorisation thereof.

A process and system for solvent deasphalting a bitumen-containing feedstock are described. The process can include solvent deasphalting the bitumen-containing feedstock, which can include contacting the bitumen-containing feedstock with a deasphalting solvent to induce precipitation of asphaltenes and produce a diluted bitumen stream comprising deasphalted oil and asphaltene precipitates, and subjecting the diluted bitumen stream to centrifugal separation to recover an overflow stream comprising diluted deasphalted oil and an underflow stream comprising the asphaltene precipitates and residual deasphalting solvent. The process can also include subjecting the underflow stream to separation in a clarifying column to produce a solvent fraction enriched in solvent and depleted in asphaltene precipitates, and an asphaltenes fraction enriched in asphaltene precipitates. Also described is a process for producing a diluent- derived deasphalting solvent from deasphalted oil, and a mixing device for contacting a bitumen- containing feedstock stream with a deasphalting solvent stream to produce a diluted bitumen stream.
