[0045] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0046] The inventor found in actual work that configuration software is a software tool for creating and managing industrial automation systems. It has a graphical user interface and can configure and monitor devices, collect and process real-time data, generate reports and trends, etc. At the same time, due to the fact that the existing oil refining devices mostly classify data control in a single-point manner, lacking overall and centralized management, in view of the above technical problems, a real-time monitoring method and device for corrosion data of an oil refining device based on configuration software are proposed in the embodiments of the present invention.

[0047] Refer to Figure 1 As shown, in the embodiments of the present invention, a real-time monitoring method for corrosion data of an oil refining device based on configuration software is provided, and the method may include the following steps:

[0048] Step S11: Based on the process flow and corrosion mechanism of the oil refining device, establish an initial corrosion flow chart of the oil refining device.

[0049] In the specific implementation of this step, based on the process flow of the oil refining device, according to similar operating conditions and working media, devices or subsystems with the same or similar corrosion mechanisms and the same equipment materials are divided into an independent corrosion loop to establish an initial corrosion flow chart of the oil refining device.

[0050] Refer to Figure 2 As shown in the example, in the embodiments of the present invention, an oil refining device of the reaction system of a 3 million tons / year diesel hydrogenation unit is taken as an example for illustration. Among them, Figure 2 is the process flow chart of the oil refining device. Based on the above process flow chart and corrosion mechanism, an initial corrosion flow chart as shown in Figure 3 is established.

[0051] Step S12: Based on the initial corrosion flow chart, determine the monitoring and detection points and the types of monitoring and detection parameters associated with the monitoring and detection points.

[0052] This step is based on the initial corrosion flow chart to determine the monitoring and detection points in the initial corrosion flow chart and the types of monitoring and detection parameters associated with the monitoring and detection points. In this step, the monitoring and detection points include monitoring point positions and detection point positions. The monitoring points are for implementing online data, and the detection points are for offline detection data.

[0053] Among them, the above monitoring and detection points may include: key process operation parameter points, equipment corrosion detection points, and / or equipment locations; the types of monitoring and detection parameters associated with the above monitoring and detection points may include: pressure, temperature, flow rate, on-line probe, on-line thickness, and chemical analysis results. The on-line probe in this step is a way to detect the corrosion thickness.

[0054] Step S13: Based on the initial corrosion flow chart, the determined monitoring and detection points, and the types of detection parameters associated with the monitoring and detection points, use configuration software to generate a final corrosion flow chart, and classify and mark the relevant corrosion data points and corrosion mechanisms on the final corrosion flow chart.

[0055] In this step, using the configuration software to generate the final corrosion flow chart may specifically include: using the configuration software to draw the equipment and pipelines included in the refinery unit to generate the final corrosion flow chart based on the monitoring and detection points and the types of detection parameters associated with the monitoring and detection points.

[0056] Refer to Figure 4 As shown, use the configuration software to draw the equipment and pipelines and form the final corrosion flow chart, and mark the pressure, temperature, flow rate, on-line probe, on-line thickness measurement, chemical analysis (sulfur content, nitrogen content, chlorine content, etc.), equipment attribute points, and the corrosion mechanism of each point (high-temperature hydrogen, hydrogen sulfide corrosion, low-temperature NH3-HCl-H2S-H2O corrosion, NH4CL salting, NH4HS salting corrosion, heating furnace flue gas dew point corrosion, etc.), as shown in Table 1 below:

[0057] Table 1 List of points on the corrosion flow chart

[0058]

[0059]

[0060] Step S14: Based on the configuration software, perform variable parameter definition and configuration for the types of monitoring and detection parameters associated with the monitoring and detection points in the final corrosion flow chart.

[0061] In this step, based on the configuration software, perform variable parameter definition and configuration for the key process operation parameters, corrosion monitoring and detection data, and equipment operation status data in the final corrosion flow chart. Configure variables such as pressure, temperature, raw material chemical analysis, on-line probe, on-line thickness measurement, etc., as shown in Table 2 below:

[0062] Table 2 List of defined variables

[0063]

[0064]

[0065]

[0066] Step S15: Based on the configuration software, perform device communication configuration on the defined and configured variables to associate relevant detection devices or data interfaces.

[0067] This step is to perform device configuration, that is, to associate relevant sensors, instruments or custom data interfaces, and define communication protocols, data sources, acquisition frequencies, alarm logics, etc. As shown in Table 3 below:

[0068] Table 3 Custom Interface List

[0069]

[0070] Step S16: Bind the monitoring points and corresponding variable parameters in the final corrosion flow chart.

[0071] After Steps S13, S14, and S15 are completed, this step binds the points marked in the corrosion flow chart (mainly variable data) to the corresponding variables. For example, for the actual temperature of the heating furnace, bind the defined variable "Actual Operating Temperature of Heating Furnace F101" to the variable at the corresponding point in the corrosion flow chart, as shown in Table 4 below:

[0072] Table 4 Point-Variable Association Table

[0073]

[0074]

[0075] Step S17: Run the final corrosion flow chart to perform real-time monitoring of the corrosion data of the refinery unit.

[0076] After all variable bindings in the corrosion flow chart are completed in Step S16, deploy the corrosion flow chart; then open the running version of the corrosion flow chart to monitor the corrosion data in real time. Refer to Figure 5 as shown, the final corrosion flow chart completes real-time monitoring.

[0077] Based on the process flow and corrosion mechanism of the refinery unit, the present invention uses configuration software to configure on-site device sensors, instruments or custom data interfaces, collect and process corrosion data, and finally centrally, uniformly and real-time monitor the device corrosion factor data in the form of a corrosion flow chart, supplemented by corrosion mechanism and alarm configuration, to achieve visual monitoring and analysis of the device corrosion data, improve the device corrosion control level, and reduce the device corrosion risk.

[0078] Furthermore, this method uses configuration software to centrally, visually and real-time monitor the corrosion factor data in the form of a corrosion flow chart, solves the problem of discrete distribution of corrosion data, improves the corrosion monitoring efficiency, and enhances the corrosion alarm and analysis capabilities.

[0079] Furthermore, based on the process flow and corrosion mechanism of the refinery unit, a corrosion flow chart is drawn and corrosion data is marked, realizing visual real-time monitoring of corrosion data in a "surface" manner instead of a "point" manner. Furthermore, by associating the corrosion mechanism and configuring an alarm strategy in the corrosion flow chart, real-time control of corrosion alarms is achieved.
