Description

Technical Field

[0001] This invention belongs to the field of industrial production technology, specifically relating to a material balance management method, system, equipment, and storage medium. Background Technology

[0002] Currently, the material balance accounting method for the entire petrochemical plant is mainly divided into three steps: unit balance, tank area balance, and overall plant balance. Materials are sent from the tank area to the units, and the units generate unit balance reports based on their flow meters, calculating the unit's processing volume, output, and yield. The tank area generates tank area balance reports based on its level gauges and flow meters, calculating the tank area's receipts, dispatches, and inventory. However, there is a measurement discrepancy between the unit's flow meter receipts and the tank area dispatches, which needs to be recalculated. During scheduling and accounting, data from multiple sources needs to be collected for comparison and verification, making the accounting process complex.

[0003] Patent CN 118469059 A discloses a production management method for material balance in petrochemical plants. The method includes: S1: simultaneously inputting basic data and external planning data into an order fulfillment model, which includes a delivery method optimization module, a tank area planning module, and an off-site inventory replenishment module, outputting first data; S2: inputting the first data and basic data from S1 into a port vessel scheduling model, outputting result data; the output result is input to an output port, which includes at least a manual verification and call module for manual verification and adjustment based on external plans to meet actual production scheduling needs, ultimately outputting a production schedule guided by material balance. This prior art has the following drawbacks: lack of a standardized data flow system; isolated data between equipment and tank area systems; no data sharing mechanism; requiring manual cross-system data collection; non-standardized material movement operation procedures; manual accounting process; and lack of clear accounting priorities. These are the shortcomings of the prior art.

[0004] In view of this, it is very necessary to provide a material balance management method, system, device, and storage medium to solve the above-mentioned defects in the prior art. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a material balance management method, system, equipment, and storage medium to solve the above-mentioned technical problems.

[0006] In a first aspect, the present invention provides a material balance management method, comprising the following steps: Step S1: The step of constructing a standardized material flow model, used to establish material standards, location standards, movement standards, material standards for locations, flow meter models, and movement path standards; In the material standard, materials include purchased materials, sold materials, work-in-process, and finished products; The location standard includes equipment, pipelines entering and exiting the equipment, oil tanks, oil receiving and dispatching lines, loading arms, and oil pools; Mobile standards include receiving devices, transmitting devices, external purchases, external sales, oil transfer, compounding, direct supply, and water cutting; The material standards for a location include the materials that can be matched with that location; The flow meter model includes establishing a flow meter ledger related to material metering; The movement path standard includes the source point, destination point, movement type, flow meter tag number or calculation formula.

[0007] Step S2: The step of building a data sharing mechanism for data sharing between the material flow standardization model and external systems; External systems include inbound and outbound metering systems, tank farm inventory management systems, and unit production reports.

[0008] Step S3: The steps for material movement operations, used to standardize the selection of locations and paths for material movement under normal or abnormal conditions; Under normal circumstances, when material movement begins, a location is selected, the corresponding movement path is chosen, and the movement is confirmed to start. The model records the start time and the flow rate at that time. ; When the material movement ends, select a location, select the corresponding moving path, confirm the end of the movement, and the model records the end time and the flow rate at that time. And calculate the cumulative value of tank flow during that time period. Calculate the amount of movement; Among them, the cumulative traffic value The mathematical expression is ; Abnormal situations include operator delays in starting / stopping and operator omissions. When operators delay starting / stopping the tank, the model can adjust the start and end times from existing operation records. By querying historical data, the model can re-obtain the flow rate value at the start time of the tank. Flow rate at the end time Calculate the amount of movement; If an operator misses an operation, the model can directly add a new operation record in the operation log, setting the start and end times, and the model will then re-acquire the flow value at the start time. Flow rate at the end time Calculate the movement amount.

[0009] The mathematical expression for calculating the movement is: ,in, This represents the cumulative flow rate of storage tank 1. This represents the cumulative flow rate of storage tank 2.

[0010] Step S4: The step of summarizing data and performing material balance accounting. The data is summarized, and material balance accounting is performed on each oil tank one by one according to the accounting order.

[0011] The data includes data on external purchases and sales, tank farm inventory, and tank farm receiving and distribution movement data; The accounting order is as follows: Level 1: Purchases and sales; Level 2: Direct delivery to the unit; Level 3: Single tank movement, where the movement amount = tank measurement; Level 4: Multiple tank area movements, where if only one movement amount is not confirmed, that movement amount = tank area measurement - other movement amounts. Level 5: Cross-regional transfer of tank farms, where both parties must confirm the data before it is entered into the system; During the accounting process, the confirmed quantities are used for both the source and destination points of each movement to ensure data consistency and material balance across the entire plant.

[0012] Material balance calculations are performed for each oil tank individually. The model automatically loads all relevant movement records for that oil tank and loads statistical reports from related parties to adjust the movement amount of the records.

[0013] Secondly, the technical solution of the present invention also provides a material balance management system, including a material flow standardization model construction module, a data sharing construction module, a material movement operation module, and a material balance accounting module; The material flow standardization model construction module is used to establish material standards, location standards, movement standards, material standards for locations, flow meter models, and movement path standards. The data sharing module is used for data sharing between the standardized material flow model and external systems. The material movement operation module is used to standardize the selection of points and paths for material movement under normal or abnormal conditions. The material balance accounting module performs material balance accounting for each oil tank one by one based on the accounting order.

[0014] Thirdly, the present invention also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor; when the processor executes the program, it implements the material balance management method as described in the first aspect.

[0015] Fourthly, the present invention also provides a computer-readable storage medium, wherein the computer program, when executed by a processor, implements the material balance management method as described in the first aspect.

[0016] The beneficial effects of the present invention are that the material balance management method, system, equipment and storage medium provided by the present invention provide a unified benchmark for all process data by constructing a standardized material flow model, and realize data interoperability between the material flow standard model and external systems by constructing a data sharing mechanism, thereby reducing the cost of manual data collection, standardizing material movement standards, clarifying accounting priorities and improving the efficiency of material balance accounting.
