Therefore, it is possible to perform training corresponding to various types of operation states regardless of the state of the actual plant or the state of the alternative fluid circulating in the actual plant. In addition, training at the actual operating speed of the actual plant results in very inefficient training, but by changing the simulator calculation speed, the reproduction time of each operating situation can be adjusted arbitrarily, and the simulator calculation speed can be reduced.

According to this plant training apparatus, although the level of the alternative fluid stored in the vessel and the actual processing fluid is different due to the difference between the alternative fluid and the actual processing fluid, the simulator calculated the level of the alternative fluid stored in the vessel. Since it is increased or decreased according to the level of the actual processing fluid, the field charge training can be performed more practically.

  Furthermore, when a field operation is performed in the actual plant, the simulator preferably calculates the operation status of the actual plant reflecting the field operation.

Regardless of the state of the alternative fluid circulated in the actual plant, it is possible to perform training corresponding to various types of operating conditions. Also, training at the actual speed of the actual plant results in very inefficient training, but by changing the simulator calculation speed, the reproduction time of each operating situation can be arbitrarily adjusted, and the simulator calculation speed increases. Therefore, efficient training can be performed.

As shown in FIG. 2, in the light oil desulfurization plant 100, in order to purify light oil containing impurities such as sulfur, first, the raw material light oil is heated in a heating furnace 20, reacted with hydrogen in a reaction tower 30, and then subjected to high pressure separation. Gas and liquid are separated by the vessel 40 and the low pressure separation vessel 50. Thereafter, the gas is separated by the stripper 60 and the separated gas is refluxed from the tower top separation vessel 70 to the stripper, whereby a refined light oil can be produced. The high-pressure separation vessel 40, the low-pressure separation vessel 50, the stripper 60, and the tower top separation vessel 70 function as a vessel that stores the actual processing fluid and the alternative fluid.

To be prevented.

  The auxiliary pipe S bypasses the alternative fluid from the heating furnace 20 and the reaction tower 30 and adjusts the level of the alternative fluid stored in the high pressure separation vessel 40, the low pressure separation vessel 50, the stripper 60, and the tower top separation vessel 70. It is. For this reason, the auxiliary pipe S supplies the alternative fluid bypassing the heating furnace 20 and the reaction tower 30 to the top of the high-pressure separation vessel 40, and supplies the alternative fluid to the high-pressure separation vessel 40 and the high-pressure separation vessel.

In addition, when lowering the level of the alternative fluid stored in the tower top separation vessel 70, the substitute fluid is discharged from the tower top separation vessel 70 using the piping for the actual processing fluid.

  During the training, the alternative fluid is circulated through these auxiliary pipes S, so that the alternative fluid bypasses the heating furnace 20 and the reaction tower 30, and the high-pressure separation vessel 40, the low-pressure separation vessel 50, the stripper 60, and the top of the tower. The level of the separation vessel 70 is adjusted.

  In addition, although detailed description is abbreviate | omitted, in the light oil desulfurization plant 100, the various auxiliary piping required in order to circulate alternative fluid and to perform training other than the auxiliary piping S mentioned above is provided.

  Further, in the light oil desulfurization plant 100, as shown in FIGS. 1 and 2, a plurality of flow meters f for detecting the flow rate of the main processing fluid or the alternative fluid flowing in the pipe, and the temperature of the main processing fluid or the alternative fluid are set.

In the pressurizing device g, the pump pressurizes and sends out liquids such as light oil and water, and the compressor pressurizes (compresses) and sends out gases such as hydrogen and nitrogen.

  The flow meter f, the thermometer t, and the pressure gauge p are each equipped with a display that displays the detected flow rate, temperature, and pressure of the processing fluid or alternative fluid. For this reason, the flow meter f, the thermometer t, and the pressure gauge p also function as a display device that displays the state quantities (flow rate, temperature, and pressure) of the main processing fluid or the alternative fluid that is the operating state of the light oil desulfurization plant 100. .

  The valve v is opened / closed by the operation control of the DCS 300 and the valve v is opened / closed by a field operation in charge of the field. The valve v that is opened and closed by the field operation is, for example, a valve v for adjusting the level of the vessel when the alternative fluid is circulated through the light oil desulfurization plant 100. A dummy valve v for training is attached to the valve v on which this field operation is performed. These valves v are attached with a display for displaying the valve opening degree of the valve v opened and closed by the operation control of the DCS 300 or the field operation. For this reason, the valve v also functions as a display device that displays the state quantity (opening degree) of the valve v that is the operating state of the light oil desulfurization plant 100. In the present embodiment, only the valve v is described as being controlled by the operation control of the DCS 300, but various devices are actually controlled by the operation control of the DCS 300.

  The simulator 200 is a dynamic simulator that simulates the operation state of the entire diesel oil desulfurization plant 100 when the actual processing fluid is circulated through the diesel oil desulfurization plant 100. The simulator 200 is mainly composed of a computer such as a CPU and a memory, and performs simulation according to a predetermined program. Then, the simulator 200 performs simulation based on the board operation of the DCS 300, the field operation of the light oil desulfurization plant 100, and the like, and shows the operation state of the light oil desulfurization plant 100. Various state quantities such as the valve opening degree of the valve v attached to each pipe, the level of the actual processing fluid stored in the high pressure separation vessel 40, the low pressure separation vessel 50, the stripper 60, and the tower top separation vessel 70, Output as simulation results (calculation results).

  The DCS 300 is a control device that performs operation control of the light oil desulfurization plant 100. For this reason, the DCS 30 is provided with a training DCS board 310 operated by a person in charge of the training, an operation DCS board 320 operated by the trainer, and a DCS controller 330 that controls the operation of the light oil desulfurization plant 100. .

  The training DCS board 310 is communicably connected to the simulator 200 and is an operation panel that virtually controls the operation of the light oil desulfurization plant 100 using the simulator 200. The training DCS board 310 is provided with an input device (not shown) for receiving an operation input in charge of the board and a display device (not shown) for displaying various state quantities as simulation results of the simulator 200. When an operation control instruction for controlling the operation of the light oil desulfurization plant 100 is performed by operating the DCS board 310 for training, the operation state of the light oil desulfurization plant 100 is simulated by the simulator 200 based on the operation control instruction. Instead of the various state quantities of the plant 100, various state quantities that are simulation results of the simulator 200 are displayed on the training DCS board 310. That is, various state quantities when the diesel oil desulfurization plant 100 is virtually controlled by the simulator 200 are displayed on the training DCS board 310. Note that the diesel oil desulfurization plant 100 cannot be directly operated and controlled from the training DCS board 310.

  The operation DCS board 320 is connected to the DCS controller 330 so as to be communicable, and is an operation panel for controlling the operation of the light oil desulfurization plant 100 by the DCS controller 330. The DCS board 320 for operation is provided with an input device (not shown) that receives an operation input of the trainer, and a display device (not shown) that displays various state quantities of the light oil desulfurization plant 100 and various state quantities of the simulation results. It has been. When an operation control instruction for controlling the operation of the light oil desulfurization plant 100 is performed by operating the DCS board 320 for operation, the operation control of the light oil desulfurization plant 100 is performed by the DCS controller 330 based on the operation control instruction. The DCS board 320 displays various state quantities of the light oil desulfurization plant 100 and various state quantities obtained as a result of simulation.

  The DCS controller 330 is a control unit that controls the operation of the light oil desulfurization plant 100. The DCS controller 330 is communicably connected to the driving DCS board 320 and the simulator 200. Then, the DCS controller 330 performs operation control of the light oil desulfurization plant 100 based on the operation control instruction from the operation DCS board 320.

  The DCS controller 330 is communicably connected to a flow meter f, a thermometer t, a pressure gauge p, a valve v, and a pumping device g provided in the light oil desulfurization plant 100, and is also connected to the operation DCS board 320 and the simulator 200. Is communicably connected. When the valve opening and the state of the pumping device g which are various state quantities of the light oil desulfurization plant 100 are detected in the valve v and the pumping device g, the DCS controller 330 detects these various states from the valve v and the pumping device g. Get the quantity. These various state quantities can be acquired by wire or wireless using a mobile PC (Personal Computer) or the like. Then, the DCS controller 330 transmits various state quantities acquired from the light oil desulfurization plant 100 to the operation DCS board 320 and the simulator 200.

  Further, when the simulation result is output from the simulator 200, the DCS controller 330 controls the operation of the light oil desulfurization plant 100 so that the various state quantities of the light oil desulfurization plant 100 match the various state quantities of the simulation result. Various control setting values such as opening and closing v, starting and stopping of the pressure feeding device g, and flow rate are changed. At this time, the DCS controller 330 matches only the state quantity that can be matched with the simulation result, such as the flow rate of the alternative fluid, with the simulation result. Note that the DCS controller 330 partially opens and closes the valve v, starts and stops the pumping device g, and changes various control setting values such as the flow rate based on the operation of the operation DCS board 320.

  Then, the DCS controller 330 displays various state quantities of the simulation result on the flow meter f, the thermometer t, the pressure gauge p, and the valve v of the light oil desulfurization plant 100. That is, the DCS controller 330 controls the operation of the light oil desulfurization plant 100 based on the simulation result of the simulator 200, but the simulation result of the simulator 200 is used as the flow meter f, temperature regardless of the actual state quantity in the light oil desulfurization plant 100. Display on meter t, pressure gauge p and valve v.

  Further, when the field operator performs the opening / closing operation of the valve v and the start / stop operation of the pumping device g, the DCS controller 330 displays the valve opening degree and the state of the pumping device g, which are the field operation results, as a simulator. 200 is reflected in the simulation of the light oil desulfurization plant 100 by 200. The field operation result may be reflected in the simulation by transmitting it directly to the simulator 200 without going through the DCS controller 330.

  Next, the operation of the plant training apparatus 1 and the training method will be described.

  First, in order to perform the operation control training of the light oil desulfurization plant 100, when the board person in charge performs the board operation of the training DCS board 310, the training DCS board 310 transmits an operation control instruction to the simulator 200. Then, the simulator 200 simulates the operation state of the light oil desulfurization plant 100 based on this operation control instruction, and calculates various state quantities such as flow rate, temperature, pressure, and valve opening as simulation results. The simulator 200 transmits the simulation result to the training DCS board 310 and also to the DCS controller 330. Then, the training DCS board 310 displays the simulation result transmitted from the simulator 200 on the display. In this way, the board person in charge performs operation control of the virtual diesel oil desulfurization plant 100 using the simulator 200 by performing the board operation of the training DCS board 310 while monitoring the simulation result displayed on the display device. Because it can be done, practical training can be done.

  On the other hand, the DCS controller 330 obtains the valve opening and the state of the pumping device g, which are various state quantities of the light oil desulfurization plant 100, from the valve v and the pumping apparatus g, and the simulation results of the various state quantities transmitted from the simulator 200. To get. Then, the operation DCS board 320 displays various state quantities of the light oil desulfurization plant 100 acquired by the DCS controller 330 and various state quantities of the simulation result.

  Then, when the trainer performs the board operation of the operation DCS board 320 while viewing these displays, the operation DCS board 320 transmits an operation control instruction to the DCS controller 330 to operate the light oil desulfurization plant 100, and the DCS. The controller 330 performs operation control of the light oil desulfurization plant 100 based on this operation control instruction. Then, in the light oil desulfurization plant 100, operation is controlled by the DCS controller 330, and an alternative fluid is circulated instead of the actual processing fluid, and the alternative fluid is used as the heating furnace 20, the reaction tower 30, the high-pressure separation vessel 40, and the low-pressure separation vessel. 50, the stripper 60, the top separation vessel 70, and the like.

  Further, the DCS controller 330 performs display control of the flow meter f, the thermometer t, the pressure gauge p, and the valve v based on the simulation result transmitted from the simulator 200, and the flow meter f, the thermometer t, and the pressure gauge p. And the valve v display the flow rate, temperature, pressure, and valve opening state as simulation results of various state quantities. As a result, the flow meter f, the thermometer t, the pressure gauge p, and the valve v display various state quantities similar to the actual processing fluid circulated in the light oil desulfurization plant 100. More practical training can be performed by monitoring the meter f, the thermometer t, the pressure gauge p, and the valve v.

  Further, the DCS controller 330 adjusts various state quantities of the light oil desulfurization plant 100 to the simulation result of the simulator 200 based on the simulation result transmitted from the simulator 200 or from the operation DCS board 320 based on the simulation result. On the basis of the operation control instruction, the operation control of the light oil desulfurization plant 100 is performed, and the valve v is opened and closed and the pumping device g is started and stopped. At this time, in the high pressure separation vessel 40, the low pressure separation vessel 50, the stripper 60, and the top separation vessel 70, the level of the alternative fluid is different from the level of the actual processing fluid. Therefore, the DCS controller 330 performs operation control of the light oil desulfurization plant 100 based on the simulation result transmitted from the simulator 200 or based on the operation control instruction from the operation DCS board 320 based on the simulation result. The valve v attached to the auxiliary pipe S is opened and closed. Then, by appropriately flowing an alternative fluid (water) through each auxiliary pipe S, the levels of the high-pressure separation vessel 40, the low-pressure separation vessel 50, the stripper 60, and the tower top separation vessel 70 become the same level as the simulation result level. Adjust as follows. Thereby, in the light oil desulfurization plant 100, since the alternative fluid is circulated in the same manner as the actual processing fluid, the field person can experience the same atmosphere and feeling as when the actual processing fluid is circulated in the piping of the light oil desulfurization plant 100. Can do.

  Then, when the field operator performs the opening / closing operation of the valve v or the start / stop operation of the pressure feeding device g by the field operation, the valve opening degree, the state of the pressure feeding device g, and the like, which are the field operation results, are transmitted via the DCS controller 330. Or directly transmitted to the simulator 200. When the field operation result is transmitted to the simulator 200, the simulator 200 reflects the valve opening as the field operation result in the simulation and calculates various state quantities of the light oil desulfurization plant 100. When the simulation results of various state quantities are calculated, the DCS controller 330 sends the flow rate, temperature, pressure, and simulation results to the flow meter f, the thermometer t, the pressure gauge p, and the valve v of the light oil desulfurization plant 100. Display the valve opening. Thereby, the person in charge of the field can confirm changes in various state quantities of the light oil desulfurization plant 100 due to the field operation.

  It should be noted that these trainings can be performed only for the board in charge by a combination of the training DCS board 310 and the simulator 200. Moreover, only the field charge can be trained by the combination of the DCS 300 and the light oil desulfurization plant 100. Further, by combining with the simulator 200, the DCS 300, and the light oil desulfurization plant 100, it is possible to perform training only for the field staff or training in cooperation between the board staff and the field staff.

  As described above, according to the plant training apparatus 1 according to the present embodiment, by operating the training DCS board 310, the simulator 200 is used to virtually control the light oil desulfurization plant 100 without operating and controlling the light oil desulfurization plant 100. Therefore, regardless of the state of the alternative fluid circulated in the light oil desulfurization plant 100 or the light oil desulfurization plant 100, training corresponding to various types of operation states can be performed. In addition, if training is performed at the actual operation speed of the light oil desulfurization plant 100, the training becomes very inefficient. However, by changing the simulation speed of the simulator 200, the reproduction time of each operation situation can be arbitrarily adjusted, and the simulation speed is increased. By raising, efficient training can be performed. Furthermore, by controlling the operation of the diesel oil desulfurization plant 100 based on the calculation result of the simulator by operating the DCS board 320 for operation, the person in charge of the board that controls the operation of the diesel oil desulfurization plant 100, and the monitoring and various operations of the diesel oil desulfurization plant 100 are performed. You can conduct training in cooperation with the field personnel who do the above.

  Moreover, according to this plant training apparatus 1, since various state quantities calculated by the simulator 200 are displayed on the flow meter f, the thermometer t, the pressure gauge p, and the valve v of the light oil desulfurization plant 100, the light oil desulfurization plant 100 and the light oil are displayed. Regardless of the state of the alternative fluid circulated through the desulfurization plant 100, the field charge training can be more practical.

  Further, in the high-pressure separation vessel 40, the low-pressure separation vessel 50, the stripper 60, and the tower separation vessel 70, the levels of the stored alternative fluid and the actual processing fluid differ depending on the difference between the alternative fluid and the actual processing fluid, but the high-pressure separation Training in charge of the field is more practiced in order to increase or decrease the level of the alternative fluid stored in the vessel 40, the low pressure separation vessel 50, the stripper 60, and the top separation vessel 70 according to the actual processing fluid level calculated by the simulator 200. Can be done automatically.

  Further, the simulator 200 can calculate changes in various state quantities of the light oil desulfurization plant 100 that change due to the field operation by simulating reflecting the field operation. It is possible to simulate the change of the state quantity.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above embodiment, the light oil desulfurization plant 100 has been described as an example of an actual plant. However, any plant may be used as long as it is dangerous if training is performed by circulating an actual processing fluid.

  In the above embodiment, the simulator 200 has been described as being separate from the DCS 300, but may be incorporated as a function of the DCS 300.

  In the above embodiment, the DCS controller 330 has been described as displaying the simulation result on the flow meter f, the thermometer t, the pressure gauge p, and the valve v. However, the flow rate at which the alternative fluid and the actual processing fluid are equal, etc. For the state quantity, the measured value of the alternative fluid may be displayed.

  In the above-described embodiment, the flow meter f, the thermometer t, the pressure gauge p, and the valve v displayed by the DCS controller 330 on the simulation result are the flow rate, temperature, pressure, and valve opening when the actual processing fluid is circulated.
