Stainless steel reactor thermal oil reactor matters needing attention

### Precautions for Stainless Steel and Thermal Oil Reactors

#### **Thermal Oil Reactors**

1. **Avoid Contamination:**

- Ensure no water, acids, alkalis, or impurities mix with the thermal oil during operation.

2. **Initial Cleaning:**

- Remove impurities and rust particles introduced during installation to maintain heat transfer efficiency and extend thermal oil life.

3. **Leak Prevention:**

- Use high-temperature gaskets in the heating circulation system to prevent thermal oil leakage.

4. **Heating Rate:**

- Heat the thermal oil gradually, not exceeding 20°C per hour.

- Hold the temperature at 105–120°C and 180–200°C to remove light components.

5. **Oil Quality Monitoring:**

- If the thermal oil shows signs of deterioration (e.g., discoloration or failure to meet heating standards), stop heating, test the oil, and decide whether to replace or replenish it.

#### **Stainless Steel Reactors**

1. **Mechanical Seal Installation:**

- Inspect the dynamic and static rings for scratches and clean the O-rings.

- Check the levelness of the static ring and the verticality of the stirring shaft, adjusting as needed.

- Ensure the mechanical seal is evenly stressed and tightly connected.

2. **Balance Tank and Sealing:**

- If a balance tank is installed, connect the sealing liquid inlet and outlet pipes, nitrogen bottle, and pressure reducer.

- Perform a static pressure test before connecting the water jacket for cooling.

3. **Cooling Requirements:**

- For medium temperatures below 80°C, use oil with high heat of vaporization, minimal impurities, and good lubrication properties for cooling.

- For temperatures above 80°C, use circulating water for cooling the bottom jacket and tank.

### Additional Guidelines

- **Thermal Oil Quality:**

- Replace or replenish oil if it no longer meets heating standards after prolonged use.

- **Coating and Cleaning:**

- Follow specific formulas and procedures for coatings like "cotton-scented" egg coatings or white oil-based paints to ensure quality and efficiency.

- **General Maintenance:**

- Regularly inspect and clean reactor components, including circulation piping, electrical cabinets, and heating elements, to prevent operational issues.

By adhering to these precautions, reactors can operate safely, efficiently, and with minimal downtime.
