[0021] The blending unit receives the crude oil stored in the transfer unit and mixes it evenly with a fixed amount of additives to form an oil mixture.

[0022] Storage unit, used to store oils processed by the blending unit.

[0023] Furthermore, the crude oil unit includes a crude oil tank 1, which is equipped with an agitator A2, a temperature sensor A3, a steam regulating valve A4, and a delivery pump A5. The agitator A2 is used to agitate the crude oil in the crude oil tank 1 to prevent crude oil stratification. The temperature sensor A3 is used to monitor the temperature of the crude oil in the crude oil tank 1. The steam regulating valve A4 is connected to an external steam pipe and is used to control the heating of the crude oil in the crude oil tank 1. The delivery pump A5 is used to deliver the crude oil in the crude oil tank 1 out.

[0024] Furthermore, the transfer unit includes a metering tank 6, which is equipped with an inlet valve B7, a flow meter B8, an outlet valve B9, and a level sensor B10. The crude oil output end of the transfer pump A5 is connected to the inlet end of the inlet valve B7. After passing through the inlet valve B7 and the flow meter B8, the crude oil enters the metering tank 6. The outlet valve B9 is used to control the outflow of crude oil from the metering tank 6, and the level sensor B10 is used to monitor the crude oil level in the metering tank 6.

[0025] Furthermore, the mixing unit includes a mixing tank 11, with the metering tank 6 being higher than the mixing tank 11. An outlet valve B9 is located between the metering tank 6 and the mixing tank 11. The mixing tank 11 is equipped with a demineralized water valve C12, a demineralized water flow meter C13, a temperature sensor C14, a level sensor C15, a stirrer C16, a steam regulating valve C17, an antibacterial agent valve C18, an antibacterial agent flow pump C19, and an oil drain valve C20. The demineralized water valve C12 is connected to an external demineralized water pipe. Demineralized water from the demineralized water pipe can enter the mixing tank 11 through the demineralized water valve C12 and the demineralized water flow meter C13. The steam regulating valve C17... 7. Connected to an external steam pipe, steam regulating valve C17 is used to control the heating of the mixed solution in the mixing tank 11. Antibacterial agent flow pump C19 is connected to an external antibacterial agent delivery pipe. The external antibacterial agent enters the mixing tank 11 through antibacterial agent metering pump C and antibacterial agent valve C18. Temperature sensor C14 is used to monitor the temperature of the mixed solution in the mixing tank 11. Liquid level sensor C15 is used to monitor the liquid level of the mixed solution in the mixing tank 11. Stirrer C16 is used to stir the mixed solution in the mixing tank 11. Oil drain valve C20 is used to control the discharge of the blended oil in the mixing tank 11.

[0026] Furthermore, the storage unit includes a high-level tank 21, which is used to store oil. The high-level tank 21 is equipped with a transfer pump D22 and an oil inlet valve D23. The oil inlet valve D23 is connected to the oil outlet valve C20. The oil that has been mixed in the mixing tank 11 can enter the high-level tank 21 through the oil outlet valve C20, the oil inlet valve D23 and the transfer pump D22.

[0027] The oil preparation process includes the following steps:

[0028] 1. The oil drain valve C20 below the mixing tank 11 for draining oil is closed, the demineralized water valve C12 is opened, and 4000 kg of demineralized water is added into the mixing tank 11 according to the set value of the demineralized water flow meter C13. When the demineralized water flow meter C13 reaches the predetermined value, the demineralized water valve C12 is closed, and at the same time the steam regulating valve C17 is opened to heat the solution in the mixing tank 11.

[0029] 2. While opening the demineralized water valve C12, open the inlet valve B7 on the metering tank 6, then zero the flow meter B8, and then turn on the transfer pump A5. The crude oil in the crude oil tank 1 enters the metering tank 6 through the transfer pump A5, the inlet valve B7, and the flow meter B8. When the cumulative flow of the flow meter B8 reaches 500 kg, turn off the transfer pump A5.

[0030] 3. When the temperature of the solution in the mixing tank 11 reaches 35℃, the temperature in the mixing tank 11 is controlled to be maintained within the range of 32℃-35℃ by using the steam regulating valve C17;

[0031] 4. Then open the antibacterial agent valve C18 and the antibacterial agent flow pump C19. Add 500-600 ppm (ppm means adding 500-600 ml of antibacterial agent per million ml of solution in the mixing tank 11) of antibacterial agent from the pipeline into the mixing tank 11 through the antibacterial agent flow pump C19. After adding the predetermined amount of antibacterial agent into the mixing tank 11, close the antibacterial agent flow pump C19 and the antibacterial agent valve C18.

[0032] 5. Stirrer C16 is turned on. Stirrer C16 stirs the mixed solution in mixing tank 11 for 20 minutes. Stirrer C16 stops stirring. At the same time, level sensor B10 monitors whether the crude oil in metering tank 6 is sufficient.

[0033] 6. When the level sensor B10 detects that the crude oil in the metering tank 6 is sufficient, the outlet valve B9 leading from the bottom of the metering tank 6 to the mixing tank 11 opens. Under the action of gravity, the crude oil in the metering tank 6 enters the mixing tank 11 through the outlet valve B9. When the level sensor B10 detects that the crude oil level in the metering tank 6 is 0, the outlet valve B9 closes, and at the same time, the agitator C16 opens to stir the mixed solution in the mixing tank 11 for 90 minutes.

[0034] 7. After the agitator C16 has been stirring for 90 minutes, the agitator C16 stops stirring, the steam regulating valve C17 is closed and heating is stopped, thus completing the preparation of the oil agent.

[0035] 8. After the oil is fully mixed, open the drain valve C20, the inlet valve D23 and the transfer pump D22 to transfer the mixed oil from the mixing tank 11 to the high-level tank 21 for storage.

[0036] All valves, pumps, sensors, and agitators in this system are controlled by a PLC controller. The system can be equipped with multiple blending units. The transfer unit can supply crude oil to different blending units. The drain valves of different blending units have the same function as drain valve C20. If you want to transfer the blended oil from different blending units to the high-level tank 21, you only need to open the drain valve, transfer pump D22, and inlet valve D23 of the specific blending unit to transfer the oil in the blending tank 11 of the specific blending unit to the high-level tank 21. The high-level tank 21 also has a liquid level sensor. If the liquid level in the high-level tank 21 is lower than 20%, the controller can issue a liquid level replenishment command to add the oil from the blending tank 11 to the high-level tank 21.

[0037] The high-level tank 21 is also equipped with a cooling valve, which is connected to an external cooling water pipe to keep the temperature inside the high-level tank 21 below 40°C.

[0038] After the oil preparation is completed, a conductivity sensor is added and a concentration detection instrument is installed inside the preparation tank 11 to detect the concentration online, which is used to control the amount of demineralized water or crude oil to be added, and then stirring continues.

[0039] The crude oil tank 1, metering tank 6, mixing tank 11 and high-level tank 21 are equipped with overcharge prevention interlocks. When the liquid level in each tank approaches the threshold, the liquid inlet is slowed down in advance to ensure the movement of the fluid and the stability of the liquid level, thereby ensuring accurate concentration mixing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
