Standard for Pressure Control of Nitrogen Sealing System for Butanone Storage Tanks?

Butanone storage tank nitrogen sealing system pressure control standard analysis

With the rapid development of the chemical industry, the safety performance and storage efficiency of storage tanks have become the focus of enterprises. As an important safety facility, nitrogen sealing system plays an irreplaceable role in the storage of flammable and volatile hazardous materials such as butanone. This paper will discuss the pressure control standard of the nitrogen sealing system of butanone storage tank in detail from the principle of the nitrogen sealing system, the pressure control standard and the matters needing attention in the practical application.

1. Butanone Storage Tank Nitrogen Sealing System Working Principle

Butanone is a colorless, flammable liquid with strong volatility. In storage tanks, the volatility of butanone may cause the oxygen content in the air to decrease, thereby causing safety hazards. When the volatilized butanone vapor is mixed with air, an open flame or an electrostatic spark may cause an explosion. Therefore, the safety of the butanone storage tank is particularly important.

The main function of the nitrogen sealing system is to isolate the air and reduce the oxygen concentration in the storage tank through the injection of inert gas (such as nitrogen), so as to prevent the possibility of mixing of butanone vapor and air to reach the explosion limit. Nitrogen is denser than air and can form an air curtain on the top of the tank to reduce the volatilization of butanone.

1. The need for pressure control The pressure control of the nitrogen sealing system is the key to ensure the safe operation of the storage tank. If the pressure is too high, it may cause the nitrogen valve to leak or the internal pressure of the storage tank exceeds the design value, which poses a safety hazard. Conversely, if the pressure is too low, the air cannot be effectively isolated, resulting in safety hazards. Therefore, it is very important to control the pressure range of nitrogen sealing system reasonably.

2. Standard pressure range According to relevant industry standards, the pressure of the nitrogen sealing system of the butanone storage tank is usually controlled at a slight positive pressure (that is, slightly higher than atmospheric pressure). The specific pressure range needs to be determined by the design of the tank, the capacity and the characteristics of the butanone. Generally, the pressure range is between 0.5 kPa and 2 kPa, which can effectively isolate the air and avoid the risk of excessive pressure.

3. Pressure regulation and alarm In order to ensure the stability of the pressure, the nitrogen sealing system needs to be equipped with a pressure regulator and a pressure alarm device. The pressure regulator can automatically adjust the injection volume of nitrogen according to the pressure change in the storage tank to maintain the pressure within the set range. The pressure alarm device can issue an alarm when the pressure is abnormal to remind the operator to deal with it in time.

3. Factors Affecting Butanone Storage Tank Nitrogen Seal System Pressure

1. Physical properties of butanone The volatility of butanone directly affects the working state of the nitrogen sealing system. The volatilization rate of butanone is greatly affected by temperature. The higher the temperature, the faster the volatilization rate and the higher the demand for nitrogen sealing system.

2. Design and material of storage tank The design and material of the storage tank also affects the pressure control of the nitrogen containment system. For example, the better the tightness of the tank, the more stable the pressure control of the nitrogen sealing system; conversely, if the tank has a leak, it may cause pressure fluctuations.

3. Operation and Maintenance The experience of the operator and the timeliness of the maintenance work will also affect the pressure control of the nitrogen sealing system. Regularly checking the pressure regulator and alarm device to ensure its normal operation is an important measure to ensure system safety.

4. summary and suggestion

The pressure control standard of the nitrogen sealing system of the butanone storage tank is a key factor to ensure the safe operation of the storage tank. Reasonable setting of pressure range, equipped with advanced pressure adjustment and alarm devices, and regular inspection and maintenance of the system can effectively reduce safety hazards and ensure the production safety of enterprises.

In practical applications, it is recommended that companies formulate detailed nitrogen sealing system pressure control plans based on their own production conditions and storage tank characteristics, and strictly implement them in accordance with relevant industry standards. Only in this way can we ensure the safety of storage tanks and improve the production efficiency and economic benefits of enterprises.
