    CROSS REFERENCE TO RELATED APPLICATION This application is related to co-pending U.S. Patent Application Serial No. 13 / 872,488 (Attorney Docket No. 267,927-1; GEEN-0485), filed concurrently with this application on April 29, 2013.
    Field of the Invention The subject matter disclosed herein relates to turbomachinery systems. In particular, the subject matter disclosed herein relates to lubricating oil in turbomachinery systems, e.g. Gas turbine or steam turbomachinery.
    Background to the Invention Turbomachinery, e.g. Gas turbines and / or steam turbines use a lubricating oil to reduce the coefficient of friction between machine components. While many turbomachinery are supplied and installed by a manufacturing and / or sales company, these turbomachinery are often maintained (throughout their life) by the customer purchasing the turbomachinery. To ensure that the lubricating oil in the turbomachine maintains a sufficient level of quality to achieve lubrication, the customer typically takes a sample of the oil and sends it to a laboratory for testing. However, some customers inappropriately take the oil samples, which can affect the accuracy of the tests. Others do not sample enough times to properly monitor the condition of the oil.
    In other industries, e.g. In the automotive industry, lubricating oil quality is estimated based on performance parameters of an automobile using empirical data associated with expected life of the oil. In these cases, a monitoring system of the motor vehicle monitors the performance of the vehicle, e.g. speed, acceleration, braking performance, etc., and estimates based on the performance of the vehicle a time when the lubricating oil will deteriorate in quality. However, these automotive systems do not test the lubricating oil to determine its quality.
    Due to the shortcomings in the above-mentioned methods for monitoring the lubricating oil quality, it is difficult to accurately judge the quality of the lubricating oil in a turbomachine.

    Detailed Description of the Invention As indicated above, the subject matter disclosed herein relates to turbomachinery systems. In particular, the subject matter disclosed herein relates to lubricating oil in turbomachinery systems, e.g. Gas turbine machines or steam turbo-machines.
    As noted herein, it may be difficult to effectively monitor the quality of lubricating oil in turbomachinery systems, which may lead to undesirable deterioration of the oil and ultimately damage to the turbomachine that relies on this oil for lubrication.
    Unlike conventional approaches, various embodiments of the invention include systems, computer program products, and related methods of analyzing a lubricating oil using test data derived from that oil. In various specific embodiments, a system includes at least one computing device configured to monitor a lubricating oil by performing actions including: determining an initial ideal remaining life for the lubricating oil; Determining a temperature-based remaining life for the lubricating oil based on a temperature measurement of the lubricating oil; Calculating a contamination factor of the lubricating oil based on a contamination sample of the lubricating oil; Determining an updated ideal life remaining for the lubricating oil based on the impurity factor, the ideal remaining life, and the temperature-based remaining life; and determining an actual life remaining for the lubricating oil based on the updated ideal remaining life and a life-loss factor.
    Various other embodiments include a computer program product having program code that, when executed by a computing device, causes the at least one computing device to monitor a lubricating oil by performing actions including: determining an initial ideal remaining life for the lubricating oil; Determining a temperature-based remaining life for the lubricating oil based on a temperature measurement of the lubricating oil; Calculating a contamination factor of the lubricating oil based on a contamination sample of the lubricating oil; Determining an updated ideal life remaining for the lubricating oil based on the impurity factor, the ideal remaining life, and the temperature-based remaining life; and determining an actual life remaining for the lubricating oil based on the updated ideal remaining life and a life-cycle loss factor.
    Various other embodiments of the invention include a system including: at least one computing device configured to analyze a lubricating oil from a turbomachine by performing actions including: predicting an initial ideal remaining life for the lubricating oil ; Determining a temperature-based remaining life of the lubricating oil based on a measured temperature of the lubricating oil; Determining a contamination factor of the lubricating oil based on a measured impurity level of the lubricating oil; Determining a Lifetime Loss Factor of the lubricating oil based on the initial ideal remaining life, the temperature-based remaining life, and the impurity factor; Determining a life loss amount of the lubricating oil based on the life loss factor and a sampling frequency of the lubricating oil; Calculating a refined ideal remaining life for the lubricating oil based on the life loss amount and the initial ideal remaining life; and predicting an actual remaining life of the lubricating oil based on the refined ideal remaining life and the lifetime loss factor.
    Fig. 1 is a flow chart illustrating a process for monitoring a lubricating oil (e.g., a lubricating oil in a turbomachine) according to various embodiments of the invention. These processes can e.g. by at least one computing device as described herein. In other cases, these processes may be performed according to a computer-implemented method for monitoring a lubricating oil. In still other embodiments, these processes may be performed by executing computer program code on at least one computing device, thereby causing the at least one computing device to monitor a lubricating oil. In general, the process may include the following sub-processes: Process P1: Determination of an initial ideal remaining life (L,) for the lubricating oil. In various embodiments, this includes obtaining information about the oil type and calculating Arrhenius Reaction Rate (ARR) for the oil type, assuming that the oil is clean (free of contaminants) and at its design temperature ( under optimal conditions). The initial ideal remaining life is the life expectancy that is expected for the lubricating oil if it were to operate under these optimum conditions for its entire life.
    The ARR is a known technique used to calculate the oxidation lifetime decay (L) in a mineral oil. The ARR may be calculated in certain embodiments according to the following equation:
    (Equation 1) where k = the rate constant of a chemical reaction; T = absolute temperature of the lubricating oil (in Kelvin); A = the pre-exponential factor; Ea = the activation energy of the lubricating oil; and R = the universal gas constant. Alternatively, the universal gas constant (R) can be replaced by the Bolzmann constant (kβ). In the case of a mineral oil simplified, the ARR can be represented by an oxidation lifetime (L) of the oil, the rate constant of the chemical reaction (k-ι) and an ideal rate constant k2 = 4750 as follows:
    (Equation 2) Process P2: Determination of a temperature-based remaining life (LT) for the lubricating oil based on a temperature measurement of the lubricating oil. The temperature-based remaining life may indicate a predicted remaining life of the lubricating oil based on the ARR and a measured temperature of the lubricating oil. This may include obtaining a measurement of the temperature of the lubricating oil. In the case where the lubricating oil comes from a turbomachine, the temperature measurement may be obtained from a temperature sensor in contact with the lubricating oil, either inside the turbomachinery or outside the turbomachine. As with the process P1, the temperature-based remaining life can be calculated according to the ARR.
    Process P3 may include calculating a contamination factor for the lubricating oil based on a (measured) contamination sample of the lubricating oil. In various embodiments, the computation includes using a transfer function to assign a qualitative weighted impurity factor to each of a plurality of measured oil properties as mentioned herein. In various embodiments, a first oil property A is assigned a weighted impurity factor X, while a second oil property B is assigned a different weighted impurity factor of Y x X, where Y is a factor, e.g. 1, 2, 3, 0,1,0,2, 0,3, is a negative factor, a percentage factor, etc. In various embodiments, the contaminant sample may be obtained from a substantially similar sample of the lubricating oil as in the temperature measurement. In various embodiments, the contaminant sample is recovered and analyzed for at least one of the following oil properties: iron particle number, water content, dielectric constant and / or particle level according to the International Organization for Standardization (ISO) to calculate an impurity factor. In some particular cases, the ISO particle level includes an average ISO level particle count calculated by averaging multiple of a plurality of ISO level particle counts for the lubricating oil. In various cases, these may include an ISO-4 level particle number, an ISO-6 level particle number, and an ISO-14 level particle number.
    Process P4 may include determining an updated ideal life remaining for the lubricating oil based on the impurity factor, the ideal remaining life, and the temperature-based remaining life. In various embodiments, the updated ideal life for the lubricating oil is calculated by subtracting an actual life loss (of the lubricating oil) from the initial ideal remaining life. In equation form: Updated ideal remaining life = initial ideal remaining life - actual life loss. The actual life loss can be calculated by multiplying the life loss factor by a sampling frequency of the lubricating oil. In equation form: Actual Lifespan Loss = Lifetime Loss Factor x Leak Detection Frequency of Lubricating Oil. The stitch probing frequency can be obtained by using a look-up table or other reference table, and can be calculated based on a known relationship between the type of oil, the volume of oil in the reservoir, and the time between successive samplings of the oil. In various embodiments, these relationships are predetermined and e.g. stored in a memory or other data memory in at least one memory device (e.g., any computing device illustrated and / or described herein) or accessible to at least one computing device. Based on a known frequency of the oil and the measured volume of oil in the reservoir, the computing device may determine an elapsed time between sampling (e.g., consecutive sample names) of the oil. This elapsed time between sample names may be used to determine a remaining (and / or elapsed) life of the oil.
    Process P5 may include determining an actual remaining life for the lubricating oil based on the updated ideal remaining life and a lifetime loss factor. In various embodiments, the actual remaining life corresponds to the life loss factor multiplied by the frequency of the lubricating oil. In equation form: Actual Lifespan Loss = Lifetime Loss Factor x Leak Detection Frequency of Lubricating Oil. In various embodiments, the life loss factor is calculated by taking the ratio of the initial ideal remaining life to the temperature-based remaining life and multiplying this ratio by the impurity factor. In equation form: Life Loss Factor = [initial ideal remaining life: temperature-based remaining life] x impurity factor.
    In many embodiments, samples of the lubricating oil are obtained at various locations of the turbomachine. In these cases, the sample data is averaged or otherwise normalized to determine a remaining life.
    In some cases, the life loss factor for the first sample data obtained (e.g., temperature data, contaminant data, frequency data, etc.) may be multiplied by the time between samples obtained and the value for the life of the fluid under optimal conditions may be subtracted. As noted, this particular example applies to the case of the first sampled sample (or the first sample taken after the oil has been replaced from the turbo machine and reservoir). After a first sample of data is available, subsequent samples form part of a moving average that includes some or all of the previously obtained samples.
    In certain embodiments, the life loss factor may be calculated as a moving average based on an operating period of the engine containing the lubricating oil (e.g., a turbomachine). In some cases, the Lifetime Loss Factor is a moving average formed over a recent (e.g., recent) period, such as the last 1-3 weeks of operation of the turbomachine.
    In various embodiments, the processes P1-P5 may be iterated (repeated) periodically (e.g., according to a x times per y-period and / or continuous) pattern to monitor the actual remaining life for a lubricating oil. In some cases, the processes P2-P5 may be repeated by e.g. get one or more new samples of the lubricating oil and the associated processes, as described above, are performed. In these cases, the process P1 need not be repeated because the initial ideal remaining life (L) may be substantially unchanged between some test intervals.
    FIG. 2 is a flowchart illustrating a process for analyzing a lubricating oil from a turbomachine according to various particular embodiments of the invention. FIG. These processes can e.g. by at least one computing device as described herein. In other cases, these processes may be performed in accordance with a computer-implemented method for monitoring a lubricating oil from a turbomachine. In still other embodiments, these processes may be performed by executing computer program code on at least one computing device, thereby causing the at least one computing device to monitor a lubricating oil from a turbomachine. In general, the process may include the following sub-processes.
    PA: prediction of an initial ideal remaining life for the lubricating oil; PB: determining a temperature-based remaining life of the lubricating oil based on a measured temperature of the lubricating oil; PC: determining a contamination factor of the lubricating oil based on a measured impurity level of the lubricating oil; PD: determining a life-loss factor of the lubricating oil based on the initial ideal remaining life, the temperature-based remaining life, and the impurity factor; PE: determining a life loss amount of the lubricating oil on the basis of the lifetime loss factor and a sampling frequency of the lubricating oil; PF: calculation of a refined ideal remaining life for the lubricating oil based on the life loss amount and the initial ideal remaining life; and PG: prediction of an actual remaining life of the lubricating oil based on the refined ideal remaining life and the life-loss factor.
    It should be understood that other processes may be performed in the flowcharts illustrated and described herein, although not illustrated, and that the order of processes may be rearranged according to various embodiments. In addition, intermediate processes may be performed between one or more described processes. The flow of processes as illustrated and described herein should not be construed as limiting the various embodiments.

    FIG. 4 shows an illustrative environment 101 that includes a monitoring system 114 for performing the functions described herein according to various embodiments of the invention. As such, environment 101 includes a computer system 102 that may execute one or more processes described herein to produce a lubricating oil, e.g. from a turbomachine, to monitor. In particular, the computer system 102 is illustrated as including the monitoring system 114, which makes the computer system 102 operable to monitor a lubricating oil by performing any of the processes described herein and implementing any of the embodiments described herein.
    The computer system 102 is illustrated as including a computing device 124 having a processing component 104 (eg, one or more processors), a memory component 106 (eg, a memory hierarchy), an input / output (I / O) component 108 (FIG. eg one or more I / O interfaces and / or devices) and a communication path 110. In general, the processing component 104 executes a program code, such as the monitoring system 114, that is at least partially defined in the memory component 106. While executing the program code, the processing component 104 may process data, which may result in reading and / or writing of transformed data from / to the memory component 106 and / or the I / O component 108 for further processing.

The I / O component 108 may include one or more I / O devices for humans that enable a user (eg, a human and / or a computerized user) 112 with the computer system 102 and / or one or more communication devices to interact to allow the system user 112 to communicate with the computer system 102 using any type of communication link. As such, the monitoring system 114 may handle a set of interfaces (e.g., graphical user interface (s), application program interface, etc.) that enable human and / or system users 112 to interact with the monitoring system 114. Further, the monitoring system 114 may collect data such as oil temperature data 60 (eg, oil temperature data obtained from a sensor system 150), oil contamination data 80 (eg, data on the level of contamination of the oil obtained from the sensor system 150), and / or oil frequency data 90 (eg, data about the frequency measurement of the oil obtained from the sensor system 150) using any solution (eg, store, retrieve, generate, manipulate, organize, present, etc.).

As such, the monitoring system 114 may be embodied as any combination of system software and / or application software. It is further understood that the monitoring system 114 may be implemented in a cloud-based computing environment in which one or more processes are performed on different computing devices (eg, multiple computing devices 24), one or more of these different computing devices being merely some of the components, such as they are illustrated and described with respect to the computing device 124 of FIG. 4.

In this case, a module 132 may allow the computer system 102 to perform a set of tasks used by the monitoring system 114, and may be separately developed and / or implemented along with other portions of the monitoring system 114. As used herein, the term "component" means any hardware configuration, with or without software, that implements the functionality described in connection therewith using any solution, while the term "module" means program code that enables the computer system 102 to implement in conjunction with this described functionality using any solution. When defined in a memory component 106 of a computer system 102 that includes a processing component 104, a module is an integral part of a component that implements the functionality. Independently, it is understood that two or more components, modules, and / or systems may share a portion / entirety of their respective hardware and / or software. Further, it is understood that some of the functionality discussed herein may not be implemented, or that additional functionality may be included as part of the computer system 102.
    When the computer system 102 includes multiple computing devices, all computing devices may include only a portion of the monitoring system 114 (e.g., one or more modules 132) defined thereon. However, it is understood that computer system 102 and monitoring system 114 merely represent various possible equivalent computer systems that may perform a process described herein.
