  • Patent number: 11933159
    Abstract: A method and system for estimating wax or hydrate deposits is desirable for the oil industry and important for assuring flow conditions and production, avoiding downtime, and reducing or preventing costly interventions. The method and system disclosed herein use artificial intelligence and machine learning techniques combined with oil well historical operational sensor data and historical operational event records (such as diesel hot flush, slick line, coil tubing, etc.) to build an oil well model. The method and system enable oil well practitioners to test and validate the built model and deploy the model online to estimate and/or detect wax or hydrate deposition status. By using one or more such models in operating an oil well, users can monitor and/or detect the status of wax of hydrate deposits in an oil well and can optimize production, maintenance, and planning for oil wells.

  • Publication number: 20240004355
    Abstract: Embodiments control and optimize batch processes. An embodiment obtains and standardizes historical operating data from a plurality of batch production runs of an industrial process. For each batch production run, the standardized operating data corresponding to the batch is partitioned into one or more stages and one or more signature for each stage is determined using the partitioned standardized data. Each determined signature is associated with a class label based upon whether output of a batch run corresponding to the signature conforms or does not conform with operational standards. A model is trained, with at least a subset of the signatures as inputs and associated class labels as outputs, to predict, based on operating data from a real-world batch process, whether output of the process will conform or not conform with the operational standards. Online predictions can be automatically or manually applied to control and optimize a batch production run.

  • Patent number: 11761427
    Abstract: Systems and methods for building predictive and prescriptive analytics of wind turbines generate a historical operational dataset by loading historical operational SCADA data of one or more wind turbines. Each sensor measurement is associated with an engineering tag and at least one component of a wind turbine. The system creates one or more performance indicators corresponding to one or more sensor measurements, and applies at least one data clustering algorithm onto the dataset to identify and label normal operation data clusters. The system builds a normal operation model using normal operational data clusters with Efficiency of Wind-To-Power (EWTP) and defines a statistical confidence range around the normal operation model as criterion for monitoring wind turbine performance. As real-time SCADA data is received by the system, the system can detect an anomalous event, and issue an alert notification and prescriptive early-action recommendations to a user, such as a turbine operator, technician or manager.

  • Patent number: 11348018
    Abstract: A system that provides an improved approach for detecting and predicting failures in a plant or equipment process. The approach may facilitate failure-model building and deployment from historical plant data of a formidable number of measurements. The system implements methods that generate a dataset containing recorded measurements for variables of the process. The methods reduce the dataset by cleansing bad quality data segments and measurements for uninformative process variables from the dataset. The methods then enrich the dataset by applying nonlinear transforms, engineering calculations and statistical measurements. The methods identify highly correlated input by performing a cross-correlation analysis on the cleansed and enriched dataset, and reduce the dataset by removing less-contributing input using a two-step feature selection procedure. The methods use the reduced dataset to build and train a failure model, which is deployed online to detect and predict failures in real-time plant operations.

  • Patent number: 10127334
    Abstract: Process engineering software applications have respective proprietary in nature and disconnected model representations of a manufacturing or processing facility. The invention method and apparatus extract from the various applications topology of equipment and streams for a facility. From the extracted data, a convertor or adapter of the invention system derives a common canonical model. To support the common canonical model (e.g., a Flowsheet object in embodiments), the converter/adapter maps or associates one or more physical assets to a logical asset, and arranges a working hierarchy of assets that can be navigated, queried and filtered.

  • Patent number: 10018273
    Abstract: A seal protection system includes a housing located on a dry side of a seal and adjacent to the frame of a pump. The housing, in part, defines a cooling chamber adjacent to the seal in which a cooling liquid may be circulated. The cooling liquid may be contained within the chamber or within a reservoir removed from the chamber. The cooling liquid circulates within the chamber to keep the seal cool even if the pump is operating under dry conditions.

  • Publication number: 20140263751
    Abstract: A foaming nozzle assembly and method of forming a foaming nozzle useable with pressure washing systems that includes a tube and a cover that cooperates with the tube. An interior surface of the tube defines a fluid path having by a first restriction, a second restriction, and an expansion chamber between the restrictions. An air path is defined between the cover and tube and fluidly connects the expansion chamber to atmosphere for introducing air to fluid associated with the fluid path. An atomizer is disposed downstream of the restrictions and expansion chamber and mixes the fluid and air to generate foam upon discharge of the mixture from the nozzle assembly.

  • Publication number: 20140263707
    Abstract: A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly that is usable with pressure washing systems includes a first body and a second body that are positionally secured relative to one another. The first body includes a fixed shaped orifice that defines the exit of a fluid spray from the nozzle assembly. The second body is disposed upstream of the first body and includes a pressure dependent variable shape orifice. The second body is formed of a resilient material that allows flexure of the second body in response to pressure of the fluid flow. Flexure of the second body manipulates the shape of the variable shape orifice and thereby allows the nozzle assembly to provide various spray patterns without user manipulation of the nozzle assembly.

  • Publication number: 20140263710
    Abstract: A pressure washer unloader valve assembly having a movable operator that manipulates an orientation of a valve body to manipulate the flow pressure is communicated downstream of the valve assembly. A cam and follower interface is formed between the operator and the valve body such that the movable operator is movable within less than 360 radial degrees to effectuate manipulation the valve assembly between a fully open and a fully closed configuration. Preferably, the valve assembly is configured to achieve the fully open or fully closed orientations of the valve assembly during a single wrist rotation of a user during interaction with the movable operator either remotely or at a pump.

  • Publication number: 20140252138
    Abstract: A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly includes a mount body, a nozzle body, and a collar that movably cooperates with the mount body. The mount body is constructed to cooperate with a discharge end of a wand and such that the nozzle body can be captured between the mount body and the collar. The nozzle body defines an uninterruptible fluid flow path through the nozzle assembly. The nozzle assembly includes an interruptible fluid flow path that is defined by a positional relationship between the nozzle body and the collar. The collar movably cooperates with the mount body to allow the selective combination of flows associated with the uninterruptible and interruptible flow paths to manipulate the spray pattern generated by the nozzle assembly.

The wand includes a trigger and a nozzle that are exposed to the pressurized fluid path. The wand includes a treatment fluid path that is isolated from the pump pressurized fluid path. A reservoir configured to receive a treatment agent is disposed in the treatment fluid path and is connected between the water source and an outlet proximate the nozzle. A control is connected to the wand proximate the trigger to allow selective introduction of treatment agent contained in the reservoir to be introduced into the pressurized fluid flow downstream of the nozzle.
