Summary:

**The operating procedure for tubular reactors (pipeline reactors) can be summarized as follows, along with relevant precautions**:

### **I. Installation and Inspection**

1. **Device Location**

- The reactor should be installed in a dry, well-ventilated environment, away from heat sources, flammable and explosive materials, and corrosive substances.

- If multiple pieces of equipment are installed, they must be arranged separately. Each operating room shall have a direct exit to the outdoors to ensure adequate ventilation.

2. **Foundation Stability**

- The reactor vessel must be placed on a solid concrete foundation to prevent equipment displacement or damage caused by vibration during operation.

3. **Pipeline Connections**

- Ensure that water, steam, cooling, and other pipelines are properly connected and free of obstructions.

- Check that all valves (such as the inlet valve, outlet valve, and discharge valve) are tightened but not over‑tightened, to avoid damaging the threads.

4. **Electricity Supply**

- Provide stable power, with wattage meeting the equipment’s requirements.

- The controller shall be placed flat on the workbench, with the operating ambient temperature maintained between 10 and 40°C, relative humidity below 85%, and the surrounding environment free of conductive dust and corrosive gases.

### **II. Preparations Before Operation**

1. **Equipment Inspection**

- Inspect the reactor vessel, agitator, rotating components, auxiliary equipment (such as temperature sensors and pressure gauges), safety valves, and piping to ensure they are in good condition.

- Verify that the sealing surfaces are free from dents or damage; apply lubricant to all threaded fasteners. At the joint between the male and female nuts, rotate only the nut itself to prevent relative rotation of the sealing surfaces.

2. **Cleaning and Drying**

- Thoroughly clean the interior of the reactor to remove any residues or contaminants, thereby preventing adverse effects on the reaction.

- Ensure the equipment is dry to prevent residual moisture from causing corrosion or compromising the reaction conditions.

3. **Parameter Settings**

- Set parameters such as temperature, pressure, and reaction time via the control panel.

- For example, set the upper limit for temperature alarms and define the operating temperature range (typically 20°C to 120°C), then calibrate the pressure control system to the desired values.

### **III. Operating Procedures**

1. **Adding Ingredients and Mixing**

- Open the feed valve and slowly add the specified amount of raw material to prevent material surges from damaging the equipment.

- Start the mixer to thoroughly blend the raw materials, ensuring that the reactants are fully in contact.

2. **Heating and Temperature Control**

- Activate the heating device (e.g., electric or steam heating), and gradually increase the temperature to the set point, maintaining a reasonable heating rate (e.g., ≤100°C/h).

- Stir continuously during heating to ensure uniform temperature distribution and prevent localized overheating.

3. **Reaction Process Monitoring**

- Real-time monitoring of parameters such as temperature, pressure, and rotational speed to ensure the reaction proceeds within a safe operating range.

- When using jacketed heating, first open the vent valve and then the inlet valve, gradually increasing the pressure to prevent a sudden pressure surge.

4. **Cooling and Stopping the Reaction**

- Once the reaction has reached the set time or the desired product, stop heating and open the cooling system (e.g., the cooling water valve) to rapidly cool the reaction mixture.

- Continue stirring during the cooling process until the mixture has completely cooled to a safe temperature (e.g., ≤80°C).

### IV. Unloading and Cleaning

1. **Unloading Operation**

- Open the vent valve and slowly release the pressure inside the reactor until it reaches atmospheric pressure (as indicated by the pressure gauge reading zero).

- Open the reactor lid and carefully remove the reaction product, taking care to prevent splashing or damage to the equipment.

2. **Equipment Cleaning**

- Thoroughly clean the interior of the reactor with a neutral detergent to remove any residues and stains.

- Disassemble and clean all components (such as the stirring rod, scraper, etc.) to ensure thorough cleaning with no hard-to-reach areas.

- After cleaning, inspect the seals and electronic components to ensure they are in good condition, preventing damage that could affect future use.

### **V. Maintenance and Care**

1. **Regular Inspections**

- Regularly inspect the equipment’s sealing integrity, agitator, heating/cooling system, and safety devices (such as pressure gauges and safety valves).

- Replace damaged seals or worn parts promptly to ensure the equipment operates properly.

2. **Lubrication and Calibration**

- Regularly apply lubricant to the agitator shaft, nut‑threaded fasteners, and other components to reduce wear.

- Calibrate key parameters such as temperature and pressure to ensure precise control of the reaction process.

3. **Storage Requirements**
