Abstract: A system for automatic detection of a defect in equipment may include a binary classification model trained to classify laboratory analysis results of an oil sample according to a gradient boosting algorithm, and to output a classification indicator of “good” or “defective” for the laboratory analysis results of the oil sample. The system may include a first multiclass classification model trained to classify the laboratory analysis results according to the gradient boosting algorithm if the laboratory analysis results are classified as “defective,” and to output a predicted defect type for the defect in equipment. The system may include a second multiclass classification model trained to classify the laboratory analysis results according to the gradient boosting algorithm and the predicted defect type, and to output a predicted corrective action pertaining to the equipment based on the predicted defect type for the defect in equipment.

Abstract: Techniques for managing a lubricant fluid include storing a lubricant fluid that includes liquid water in an interior volume of a reservoir, which includes a vapor space above the lubricant fluid that encloses water vapor; circulating, with a blower, a first airflow from the vapor space to an ambient environment to remove at least a portion of the water vapor to the ambient environment; circulating a second airflow to a heater in fluid communication with the vapor space within the interior volume of the reservoir; heating the second airflow with the heater; circulating the heated airflow into the vapor space to reduce a relative humidity of the vapor space; and releasing at least a portion of the liquid water from the interior volume of the reservoir through a control valve coupled to the reservoir.

Abstract: Systems and methods for automatic maintenance of lube oil quality include a storage tank for storing fresh lube oil, a lube oil reservoir containing a volume of operational lube oil, and an oil disposal tank. A first controllable flow system transports lube oil from the reservoir to the oil disposal tank, and a second controllable flow system transports fresh lube oil from the storage tank to the reservoir. Provided are a level transmitter to measure a level of lube oil within the reservoir and an antioxidant sensor to measure a concentration of antioxidant level inside the lube oil reservoir. A control system activates and deactivates the first controllable flow system based upon the concentration of antioxidant measured by the antioxidant sensor, and activates and deactivates the second controllable flow system based upon the level of lube oil measured by the level transmitter.

Abstract: A lubricating oil system includes a reservoir configured to enclose a lubricant oil; a filter assembly that includes at least one filter and is positioned in the reservoir to separate the reservoir into a first oil tank and a second oil tank, where the first oil tank fluidly is coupled to the rotating machine through an oil return line; a system pump fluidly coupled to the reservoir and configured to circulate the lubricant oil from the second oil tank to the rotating machine through an oil supply line; and a circulating pump assembly. The circulating pump assembly includes a conduit that fluidly couples the first oil tank to the second oil tank external to the reservoir, a circulating pump coupled within the conduit and including a suction coupled to the first oil tank and a discharge coupled to the second oil tank, and a media filter coupled within the conduit and between the first oil tank and the second oil tank.

Abstract: A vacuum dehydrator for removing water from lube oil including a vacuum chamber having a contaminated lube oil contact zone, a lube oil inlet for introducing a water contaminated lube oil into the contact zone, a hot air inlet for introducing a heated air stream into the contact zone, a decontaminated oil outlet fluidly connected to the decontaminated oil collection zone, and a wet air outlet fluidly connected to the disengagement zone. The lube oil inlet and the hot air inlet are configured to introduce and contact the water contaminated lube oil and the hot air in the contact zone, producing a dehydrated oil received into the decontaminated oil collection zone and a wet air stream containing entrained oil droplets received into the disengagement zone. The disengagement zone includes a tortuous divergent flow path traversing from a disengagement zone inlet to the wet air outlet.
