Methanol is a common industrial chemical used in the production of formaldehyde, acrylic ester and other chemical products. In the process of production and storage and transportation, methanol horizontal storage tank is one of the commonly used storage equipment. However, as methanol is a flammable and explosive dangerous goods, the maintenance of storage tanks needs to be extra cautious. The following are the precautions for the maintenance of methanol horizontal storage tanks.

1. Safety investigation: Before maintenance, safety investigation must be carried out on the storage tank and its surrounding environment to ensure that there are no dangerous factors such as open flame and static electricity accumulation. At the same time, eliminate toxic and harmful gases to ensure the safety of operators.

2. Ventilation: Ventilation shall be carried out on the storage tank before maintenance to ensure that there is no harmful gas residue in the storage tank. The ventilation time is generally not less than 24 hours, and it is strictly prohibited to enter the storage tank for maintenance operations before the ventilation is completely completed.

3. Grounding on the ground: Before the maintenance work, the storage tank must be grounded on the ground to prevent fire accidents caused by static electricity.

4. Fire prevention measures: the maintenance site must be equipped with sufficient fire extinguishing equipment, operators should be familiar with the use of fire extinguishers, and be ready to deal with fire emergency at any time.

5. Personnel protection: All personnel involved in maintenance operations must wear protective equipment that meets the standards, including chemical protective clothing, safety helmet, gas mask, etc.

6. Thermal control: In the maintenance process, the temperature in the storage tank should be strictly controlled to prevent fire caused by excessive temperature.

7. Mechanical equipment inspection: Before maintenance, it is necessary to conduct a comprehensive inspection of relevant mechanical equipment to ensure that the equipment operates normally and there is no hidden trouble.

8. Environmental protection: The waste generated during the overhaul must be classified and treated in accordance with regulations to protect the environment.

methanol horizontal tank maintenance work needs to attach great importance to safety, strict implementation of operating procedures to ensure the safety of operators and equipment. As employees, we should always pay attention to safe production and take preventive and control measures. I hope everyone can keep these maintenance precautions in mind to ensure production safety and avoid accidents.
