[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system used in a refinery for refining petroleum, and more particularly, to an integrated production system that achieves further cost reduction and increased profit by realizing efficiency improvement in the whole factory. About.

[0002]

2. Description of the Related Art In a petroleum refining company, a manufacturing execution computer for integrating management information and process control information is disclosed, for example, in Japanese Patent Publication No. Hei 9-503325.
However, such systems have not provided optimal information for each of the diverse personnel operating the factory. For example, personnel operating a factory are classified into managers who need management information, operators who are in charge of operating actual equipment, and production planners who mediate between management information and operation information.

FIG. 5 is an explanatory diagram of information transmission between a conventional management information zone, a process control zone, and a process information zone. The management information zone includes planning, sales and marketing information, engineering information, and maintenance information necessary for management. In the process control zone, control information on various processes constituting a refinery such as a reaction furnace, a combustion furnace, a tank, and piping is present. This control information includes, for example, information on the detection end such as the flow rate, the pressure, and the temperature, and information on the operation end such as the opening degree of the valve. The process information zone includes environmental information such as process operation monitoring and nitrogen oxide emissions.

In such information transmission, when a plan is prepared in the management information zone, it is transmitted as a set value to the process control zone. In the process control zone, plant operation is performed according to the set value. Therefore, the operation data is collected and returned to the management information zone. In the management information zone, the plan is revised based on the operation data. In this way, the process control is performed in a format dependent on the management information. And in such information transmission, many people are doing translation work.

FIG. 6 is an explanatory view of a tank existing in a refinery. For managers, capacity, weight, leakage (g
ive-away), product code, payment of excise tax, etc.
The operator can adjust the tank level, tank temperature, oil type (servic
e), full tank status (status), scheduled sampling date (S
ample Due). The process engineer reads the tank level tag name, tank temperature tag name, oil type tag name,
Tag name of minimum filling level (MinFillHeight), contents (Contai
ned Equipment) ,

[0006]

However, in the conventional information system, information is not smoothly transmitted between the management information zone, the process control zone, and the process information zone, and the entire refinery is optimized. There was a problem that it was difficult to be.

An object of the present invention is to provide an integrated refinery production system in which information is smoothly transmitted between a management information zone, a process control zone, and a process information zone.

According to claim 1 of the present invention, the management information zone carries out information processing suitable for grasping the business state from order information from the sales department and shipping / sales information from the shipping department. The process control zone is in charge of controlling various reaction towers and piping existing in the refinery. The production execution zone issues a command such as scheduling to the process control zone so as to optimally fulfill the order from the management information zone, and informs the management information zone of the production status of the process control zone. The object-oriented database unit is commonly used in the management information zone, the process control zone, and the production execution zone.

According to a second aspect of the present invention, the production execution zone is provided on-site / off-site of the refinery based on order information sent from a management information zone, inventory information and production capacity information in an object-oriented database unit. If the operation schedule 31 is determined and sent to the process control zone, the operation schedule becomes optimal for processing the order with respect to the equipment capacity. Here, as in claim 3, the operation schedule is based on the shift plan 42 of the worker.
If it is configured to include, the consistency with the labor plan is obtained.

According to a fourth aspect of the present invention, the production execution zone is obtained from information on the arrival of crude oil sent from a management information zone and inventory information on an object-oriented database unit.
If the blending / oil transfer operation schedule 32 of the refinery is determined and sent to the process control zone, an optimal blending plan and an oil transfer operation for performing the same can be realized. Further, when the inventory information is configured to include the type and amount of the crude oil for the tanks of the refinery, the transportation of the oil between the tanks can be easily determined.

The absorber delivers the C2 gas such as methane and ethane to the gas plant using the distillation gas sent from the compressor and the hydrogenated gas. The butane distillation column (debutaniser) extracts gasoline that is heavier than the butane fraction, and the propane distillation column (depro
The butane / butylene is separated in a paniser and the lighter components than propane are sent to a wax cracking tower (dewaxer).

In such a facility, the manager manages target values, current values, daily production amounts, etc. of nitrogen oxides, sulfur oxides, carbon monoxide and the like generated in the regeneration tower in the product summary window 51. .

In the apparatus configured as described above, the information used in the management information system 10, the process control system 20, and the manufacturing execution system 30 is integratedly managed using the integrated object-oriented database unit 40. Information that the user wants to use can be obtained at any time. In addition, since the amount of goods that fluctuates every moment due to orders, shipments, manufacturing conditions, and the like is reflected in the integrated object-oriented database unit 40, the operating state of the entire refinery can be easily grasped.

In the above embodiment, the case of a relatively large-scale refinery installed on a single site is shown, but the present invention is not limited to this. For example, when there is a factory in charge of manufacturing each compound such as styrene and polyethylene as in the petrochemical industry, the integrated object-oriented database unit 40, the management information system 10, the process control system 20, and the A production execution system 30 may be provided. Alternatively, when a plant for producing a plurality of compounds is organically connected as in a petrochemical complex, the integrated object-oriented database unit 40 and management information
A system 10 is provided to provide a process control system for each compound.
The system 20 and the production execution system 30 may be distributed.
