Description

Technical Field

[0001] This invention belongs to the field of phosphate ester fire-resistant oil technology, and relates to a correlation evaluation method based on the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil. Background Technology

[0002] Phosphate ester fire-resistant oils, as high-performance synthetic lubricants, are widely used in power systems (such as steam turbine electro-hydraulic control systems), aviation hydraulic systems, and high-temperature industrial equipment due to their excellent fire resistance, thermal stability, and oxidation stability. However, during long-term operation, phosphate ester fire-resistant oils are susceptible to hydrolysis or oxidation reactions caused by factors such as moisture, oxygen, and metal catalysts, leading to an increase in acid value. An increased acid value not only accelerates oil aging but also causes corrosion of system components, sludge formation, and a decline in electrical properties (such as reduced resistivity), which can, in severe cases, jeopardize the safe operation of equipment.

[0003] To delay oil aging and restore oil performance, industrial processes often employ deacidification techniques using adsorbents and ion exchange resins to regenerate phosphate ester fire-resistant oils. The core objective of deacidification is to reduce acid value; however, current technologies often focus on a single evaluation of deacidification efficiency (such as deacidification rate), neglecting the impact of the deacidification process on other key performance indicators of the oil. For example, some deacidifying agents, while removing acidic substances, may adsorb additives or introduce impurities into the oil, leading to decreased resistivity, increased water content, or deteriorated foaming properties. These implicit changes directly affect the oil's insulation properties, demulsibility, and air release properties, thereby reducing its overall performance.

[0004] Currently, the evaluation methods for the deacidification effect of phosphate ester fire-resistant oils are relatively simple, usually judging the treatment effect only by changes in acid value or deacidification rate, lacking a systematic analysis of the synergistic changes in multiple performance indicators of the oil. Existing technologies have not yet established a correlation evaluation model between the deacidification effect and key parameters such as oil resistivity, moisture content, and foaming characteristics, resulting in an inability to comprehensively assess the applicability and safety of the deacidification process. In practical applications, contradictory situations may arise where the deacidification rate meets the standard, but the overall performance of the oil deteriorates, posing potential risks to the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a correlation evaluation method for the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil, so as to solve the technical problem that the existing deacidification effect evaluation methods are singular and cannot fully reflect the impact of deacidification treatment on the comprehensive performance of oil products.

[0006] To achieve the above objectives, the present invention employs the following technical solution: In a first aspect, the present invention provides a correlation evaluation method based on the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil, comprising the following steps: Obtain initial data for the phosphate ester fire-resistant oil to be processed, including initial acid value, initial resistivity, initial moisture content, and initial foaming characteristics; The phosphate ester fire-resistant oil was subjected to deacidification treatment, and intermediate data corresponding to the phosphate ester fire-resistant oil at each time point were measured. The intermediate data included acid value, resistivity, moisture content and foam characteristics. For each time point, the deacidification rate, resistivity change rate, moisture content change value, and foaming characteristic change value of the phosphate ester fire-resistant oil are calculated based on the initial and intermediate data. With the deacidification rate on the x-axis and the resistivity change rate, moisture content change, and foam characteristics change on the y-axis, three correlation evaluation curves were plotted. Based on the trend and key points of the correlation evaluation curve, the impact of deacidification treatment on the overall performance of phosphate ester fire-resistant oil is evaluated.

[0007] Preferably, the formula for calculating the deacidification rate is:

[0008] In the formula, for Deacidification rate of phosphate ester fire-resistant oil at any time; The initial acid value of phosphate ester fire-resistant oil; for The acid value of phosphate ester fire-resistant oil at any given time.

[0009] Preferably, the formula for calculating the rate of change of resistivity is:

[0010] In the formula, for The rate of change of resistivity of phosphate ester fire-resistant oil at any given time; The initial resistivity of phosphate ester fire-resistant oil; for The resistivity of phosphate ester fire-resistant oil at any given time.

[0011] Preferably, the formula for calculating the change in moisture content is:

[0012] In the formula, for Changes in moisture content of phosphate ester fire-resistant oil at any given time; The initial moisture content of phosphate ester fire-resistant oil; for Moisture content of phosphate ester fire-resistant oil at any given time.

[0013] Preferably, the formula for calculating the change value of foam characteristics is:

[0014] In the formula, for Changes in the foaming properties of phosphate ester fire-resistant oil at any given time; The initial foaming properties of phosphate ester fire-resistant oil; for Foaming properties of phosphate ester fire-resistant oil.

[0015] Preferably, the key points of the correlation evaluation curve include: the inflection point of the deacidification rate change, the critical point where the resistivity change rate turns from positive to negative, and the points where the change values ​​of moisture content and foam characteristics exceed their corresponding preset thresholds.

[0016] Preferably, the preset threshold corresponding to the change in moisture content is no more than 50 mg / kg; and the preset threshold corresponding to the change in foam properties is no more than 50 mL.

[0017] Preferably, the method for evaluating the impact of deacidification treatment on the overall performance of phosphate ester fire-resistant oil, based on the trend and key points of the correlation evaluation curve, includes: When the deacidification rate increases, and the resistivity change rate remains positive or turns from negative to positive, while the change values ​​of moisture content and foam characteristics do not exceed their corresponding preset thresholds, it is determined that the deacidification treatment has no negative impact on the overall performance of phosphate ester fire-resistant oil or has an improving effect while improving the deacidification effect. When the deacidification rate increases to an inflection point and then tends to stabilize, but the resistivity change rate turns from positive to negative and reaches a critical point, and / or at least one of the moisture content change value and foam characteristic change value exceeds its corresponding preset threshold, it is determined that the deacidification treatment has a negative impact on the overall performance of phosphate ester fire-resistant oil.

[0018] Secondly, the present invention provides a correlation evaluation system based on the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil, comprising: Initial performance testing module: used to acquire initial data of the phosphate ester fire-resistant oil to be processed, including initial acid value, initial resistivity, initial moisture content and initial foaming characteristics; Process dynamic monitoring module: used to deacidify the phosphate ester fire-resistant oil and measure the intermediate data corresponding to the phosphate ester fire-resistant oil at each time point, including acid value, resistivity, moisture content and foam characteristics; Performance change calculation module: used to calculate the deacidification rate, resistivity change rate, moisture content change value and foam characteristic change value of phosphate ester fire-resistant oil at each time point based on the initial data and intermediate data; The correlation curve plotting module is used to plot three correlation evaluation curves with the deacidification rate on the horizontal axis and the resistivity change rate, moisture content change value, and foam characteristic change value on the vertical axis, respectively. Comprehensive performance evaluation module: used to evaluate the impact of deacidification treatment on the comprehensive performance of phosphate ester fire-resistant oil based on the trend and key points of the correlation evaluation curve.

[0019] Thirdly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method as described in any one of claims 1-8.

[0020] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves a multi-dimensional comprehensive evaluation of the deacidification process by establishing dynamic correlation curves between the deacidification rate and the rates of change in resistivity, moisture content, and foam characteristics. This method breaks through the traditional single-evaluation model that only focuses on deacidification efficiency. By capturing the synergistic changes in key performance parameters during the deacidification process, it can clearly reveal the potential impact of deacidification treatment on the oil's insulation properties, hydrolytic stability, and air release properties. Based on the evaluation mechanism of curve trends and key points, it can not only scientifically determine the optimal operating range of the deacidification process but also provide early warnings of potential oil performance degradation risks, thus providing a reliable decision-making basis for optimizing deacidification process parameters and ensuring the comprehensive performance of fire-resistant oil.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] In the description of the embodiments of the present invention, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings: The first objective of this invention is to provide a correlation evaluation method based on the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil, such as... Figure 1 As shown, it includes the following steps: Obtain initial data for the phosphate ester fire-resistant oil to be processed, including initial acid value, initial resistivity, initial moisture content, and initial foaming characteristics; The phosphate ester fire-resistant oil was deacidified, and intermediate data corresponding to the phosphate ester fire-resistant oil at each time point were measured. The intermediate data included acid value, resistivity, moisture content and foam characteristics. For each time point, the deacidification rate, resistivity change rate, moisture content change value, and foaming property change value of phosphate ester fire-resistant oil were calculated based on initial and intermediate data. With the deacidification rate on the x-axis and the resistivity change rate, moisture content change, and foam characteristics change on the y-axis, three correlation evaluation curves were plotted. The impact of deacidification treatment on the overall performance of phosphate ester fire-resistant oil was evaluated based on the trend and key points of the correlation evaluation curve.

[0030] The evaluation method provided by this invention effectively overcomes the limitations of traditional single-index evaluation by establishing a dynamic correlation between the deacidification process and multiple key performance indicators. This method first comprehensively acquires baseline data on the initial state of phosphate ester fire-resistant oil before deacidification, laying the foundation for subsequent change analysis. By synchronously tracking and measuring performance indicators at different time points during the treatment process, the timeliness and completeness of data acquisition are ensured. Furthermore, by calculating the rate or amount of change of each performance parameter relative to its initial value, absolute measurements are transformed into comparable relative trends, enhancing the comparability between different indicators. Simultaneously, this invention uses the deacidification rate, a core process indicator, as a unified abscissa, and plots its relationship curves with resistivity, moisture content, and foam characteristics, thereby intuitively linking the deacidification effect with the three key comprehensive performance characteristics of the oil: electrical properties, cleanliness, and stability. Ultimately, by comprehensively analyzing the overall trend, inflection points, and plateau periods of these correlation curves, we can scientifically assess the synergistic or potential negative impacts of the deacidification process on the overall performance of oil products while increasing acid value. This provides crucial decision-making basis for optimizing deacidification process parameters and maximizing or improving the comprehensive performance of oil products while ensuring deacidification efficiency.

[0031] The formula for calculating the deacidification rate is as follows:

[0032] In the formula, for Deacidification rate of phosphate ester fire-resistant oil at any time; The initial acid value of phosphate ester fire-resistant oil; for The acid value of phosphate ester fire-resistant oil at any given time.

[0033] The formula for calculating the rate of change of resistivity is:

[0034] In the formula, for The rate of change of resistivity of phosphate ester fire-resistant oil at any given time; The initial resistivity of phosphate ester fire-resistant oil; for The resistivity of phosphate ester fire-resistant oil at any given time.

[0035] The formula for calculating the change in moisture content is:

[0036] In the formula, for Changes in moisture content of phosphate ester fire-resistant oil at any given time; The initial moisture content of phosphate ester fire-resistant oil; for Moisture content of phosphate ester fire-resistant oil at any given time.

[0037] The formula for calculating the change in foam properties is:

[0038] In the formula, for Changes in the foaming properties of phosphate ester fire-resistant oil at any given time; The initial foaming properties of phosphate ester fire-resistant oil; for Foaming properties of phosphate ester fire-resistant oil.

[0039] This invention, by accurately calculating four core indicators—deacidification rate, resistivity change rate, moisture content change value, and foam characteristic change value—can not only clearly and objectively reflect the dynamic changes of oil in various aspects such as acid value control, insulation performance, dryness, and foam stability, but also achieve a holistic evaluation of the treatment process efficiency.

[0040] For example, key points in the correlation evaluation curve include: the inflection point of the deacidification rate change, the critical point where the resistivity change rate turns from positive to negative, and the points where the changes in moisture content and foam characteristics exceed their respective preset thresholds. The inflection point of the deacidification rate indicates a significant change in deacidification efficiency, signifying the completion of the main reaction or the onset of side reactions; the resistivity critical point reveals the depletion of the deacidifying agent's potential or the beginning of the precipitation of harmful substances; and the exceeding of thresholds for moisture and foam characteristics directly reflects the acceptable limits of oil cleanliness and stability. The effect of this multi-dimensional key point analysis is that it transforms the abstract curve trend into specific, operable process control nodes, thereby enabling precise diagnosis of the optimal endpoint of the deacidification process. By monitoring the sequence and interrelationships of these key points, the mechanism of deacidification treatment can be deeply analyzed. This not only avoids secondary problems such as decreased resistivity or deterioration of foam characteristics caused by overtreatment, but also provides scientific early warning and decision-making basis for achieving the optimal balance between deacidification effect and overall performance maintenance.

[0041] For example, methods for evaluating the impact of deacidification treatment on the overall performance of phosphate ester fire-resistant oil, based on the trend and key points of the correlation evaluation curve, include: When the deacidification rate increases, and the resistivity change rate remains positive or turns from negative to positive, while the change values ​​of moisture content and foam characteristics do not exceed their corresponding preset thresholds, it is determined that the deacidification treatment has no negative impact on the overall performance of phosphate ester fire-resistant oil or has an improving effect while improving the deacidification effect. When the deacidification rate increases to an inflection point and then tends to stabilize, but the resistivity change rate turns from positive to negative and reaches a critical point, and / or at least one of the moisture content change value and foam characteristic change value exceeds its corresponding preset threshold, it is determined that the deacidification treatment has a negative impact on the overall performance of phosphate ester fire-resistant oil.

[0042] By establishing a discriminant logic for the synergistic changes of multiple parameters, the comprehensive effects of the deacidification process are analyzed dialectically. The core of this approach lies in identifying the synergy or divergence between deacidification efficiency and changes in various key performance indicators: when an increase in the deacidification rate is accompanied by a stabilization or improvement in resistivity, and moisture and foam characteristics remain within thresholds, it indicates that the deacidification process has synergistically promoted the electrical properties, cleanliness, and stability of the oil, and is considered an ideal effect. Conversely, if resistivity deteriorates or other indicators exceed thresholds after the deacidification rate reaches a plateau, it reveals that the deacidification treatment has caused side effects such as changes in composition, introduction of impurities, or decreased system stability, and is considered to have a negative impact. This invention achieves a shift from solely pursuing deacidification efficiency to comprehensively evaluating process safety and oil suitability, providing a scientific basis for accurately determining the endpoint of the deacidification process and avoiding performance risks caused by overtreatment, ensuring the comprehensiveness and reliability of the evaluation conclusions.

[0043] In addition, the preset threshold for changes in moisture content is no more than 50 mg / kg; the preset threshold for changes in foam characteristics is no more than 50 mL. The moisture threshold is set based on the critical point of hydrolytic stability of phosphate ester oil, aiming to prevent the moisture content from rising to a level that may cause hydrolytic degradation of the oil and irreversible decrease in resistivity; the foam characteristic threshold is based on the safety margin of the oil's anti-foaming ability, used to warn of deterioration of foam stability caused by surface tension imbalance or the introduction of contaminants.

[0044] Example A phosphate ester fire-resistant oil that has been operating for 3 years at a power plant was selected as the treatment target. Its initial performance data are as follows: Initial acid value: 0.32 mg KOH / g; Initial resistivity: 5.8 × 10⁻⁶ 9 Ω cm; Initial moisture content: 220 mg / kg; Initial foaming characteristics (foaming tendency at 24℃): 180mL.

[0045] Ion exchange resin (strong base anion exchange resin) was used for deacidification treatment. Under constant temperature stirring at 65℃, samples were taken at 0.5h, 1h, 2h, 4h, 6h, 10h and 18h ​​respectively, and the acid value, resistivity, moisture content and foam characteristics were measured simultaneously. The data records are shown in Table 1.

[0046] Table 1. Changes in various indicators during the deacidification process.

[0047] Taking 6 hours as an example: Deacidification rate:

[0048] Rate of change of resistivity:

[0049] Changes in moisture content:

[0050] Changes in foam properties:

[0051] Similarly, the performance changes at the remaining time points were calculated and summarized in Table 2: Table 2 Calculation results of performance changes during deacidification process

[0052] Plotting the deacidification rate on the x-axis, we obtained three correlation curves with the rate of change in resistivity, the change in moisture content, and the change in foam characteristics. The results showed that when the deacidification rate increased within the range of 0% to 81.25%, the rate of change in resistivity was negative but the absolute value was small (i.e., resistivity increased slightly or remained relatively stable), the change in moisture content was negative (moisture decreased), and the change in foam characteristics was negative or slightly positive (foam tendency improved or remained relatively stable), indicating that the deacidification treatment was effective and did not negatively impact oil performance. However, when the deacidification rate exceeded 81.25% (e.g., reaching 84.38% and 87.50%), the rate of change in resistivity changed from negative to positive and increased significantly (indicating a significant decrease in resistivity), the change in moisture content changed from negative to positive and exceeded the preset threshold (50 mg / kg), and the change in foam characteristics increased significantly and exceeded the preset threshold (50 mL), indicating that continued deacidification would lead to a decrease in oil resistivity, an increase in moisture content, and a deterioration in foam characteristics.

[0053] In summary, for this ion exchange resin deacidification process, the optimal treatment time should be controlled within 6 hours (with a deacidification rate of approximately 81%). Although exceeding this time point can further improve the deacidification rate, it will lead to a significant decrease in the overall performance of the oil (resistivity, moisture content, and foaming characteristics).

[0054] The second objective of this invention is to provide a correlation evaluation system based on the deacidification effect and comprehensive performance of phosphate ester fire-resistant oil, comprising: Initial performance testing module: used to acquire initial data of the phosphate ester fire-resistant oil to be processed, including initial acid value, initial resistivity, initial moisture content and initial foaming characteristics; Process dynamic monitoring module: used to deacidify phosphate ester fire-resistant oil and measure intermediate data of phosphate ester fire-resistant oil at each time point, including acid value, resistivity, moisture content and foam characteristics; Performance change calculation module: used to calculate the deacidification rate, resistivity change rate, moisture content change value and foam property change value of phosphate ester fire-resistant oil at each time point based on initial data and intermediate data; The correlation curve plotting module is used to plot three correlation evaluation curves with the deacidification rate on the horizontal axis and the resistivity change rate, moisture content change value, and foam characteristic change value on the vertical axis, respectively. Comprehensive performance evaluation module: used to evaluate the impact of deacidification treatment on the comprehensive performance of phosphate ester fire-resistant oil based on the trend and key points of the correlation evaluation curve.

This system transforms complex multi-indicator dynamic correlation analysis into an efficient, standardized, and repeatable operational process, significantly improving the efficiency, consistency, and reliability of evaluation work, and providing powerful standardized tools to support the precise optimization and decision-making of deacidification processes.
