In the chemical industry, maintaining the purity and integrity of process chemicals is crucial. One of the most effective ways to achieve this is through the use of deaeration. Deaeration is the process of removing dissolved gases, primarily oxygen and carbon dioxide, from water. This process is essential for preventing corrosion and ensuring the purity of process chemicals. A well-designed deaerator system, including a deaerator storage tank, plays a vital role in safeguarding industrial processes.

Understanding Deaeration

Deaeration involves the removal of dissolved gases from water, which can cause corrosion and contamination in chemical processes. The presence of oxygen and carbon dioxide in process water can lead to the formation of corrosive acids and rust, compromising the integrity of equipment and the quality of products. By using a deaerator system, industries can effectively eliminate these gases and protect their processes.

The Role of a Deaerator System

A deaerator system consists of a deaerator and a deaerator storage tank. The deaerator is designed to remove dissolved gases from water by heating it and causing the gases to escape. The deaerator storage tank holds the deaerated water, ensuring a continuous supply for industrial processes.

  1. Deaerator: The deaerator works by heating the water to a temperature where dissolved gases become less soluble and are released. This is typically achieved through a combination of steam heating and mechanical agitation. The released gases are then vented out of the system, leaving behind deaerated water.
  2. Deaerator Storage Tank: Once the water has been deaerated, it is stored in a deaerator storage tank. This tank ensures that a steady supply of deaerated water is available for various industrial processes. The storage tank also helps in maintaining the temperature and pressure of the deaerated water, preventing the re-absorption of gases.

Importance of Deaeration in the Chemical Industry

Preventing Corrosion

Corrosion is a significant concern in the chemical industry, as it can lead to equipment failure, product contamination, and costly downtime. Dissolved oxygen and carbon dioxide are primary culprits in causing corrosion. Oxygen reacts with metals to form oxides (rust), while carbon dioxide forms carbonic acid, which further accelerates the corrosion process.

  1. Equipment Protection: By removing dissolved gases, a deaerator system protects critical equipment such as boilers, heat exchangers, and pipelines from corrosion. This extends the lifespan of the equipment and reduces maintenance costs.
  2. Process Integrity: Preventing corrosion ensures that the integrity of the chemical process is maintained. This is particularly important in applications where even minor contamination can affect product quality and safety.

Ensuring the Purity of Process Chemicals

The purity of process chemicals is paramount in chemical manufacturing. Contaminants introduced by dissolved gases can alter chemical reactions, leading to off-spec products and reduced yields.

  1. Product Quality: Deaerated water is free from dissolved gases that can cause contamination. This ensures that the chemical reactions proceed as intended, resulting in high-quality products.
  2. Consistent Results: Using deaerated water ensures that the chemical processes are consistent and reliable. This is crucial for maintaining product standards and meeting regulatory requirements.

Benefits of a Deaerator System

Implementing a deaerator system offers several benefits to the chemical industry:

  1. Improved Equipment Efficiency: By preventing corrosion, a deaerator system ensures that equipment operates at peak efficiency. This reduces energy consumption and operational costs.
  2. Reduced Maintenance Costs: Protecting equipment from corrosion minimizes the need for frequent repairs and replacements, leading to significant cost savings.
  3. Enhanced Safety: Corrosion can compromise the safety of industrial processes. By eliminating dissolved gases, a deaerator system enhances the overall safety of the facility.
  4. Optimized Process Performance: Deaerated water ensures that chemical reactions occur under optimal conditions, improving the performance and yield of industrial processes.

Choosing the Right Deaerator System

When selecting a deaerator system for your facility, consider the following factors:

  1. Capacity: Ensure that the deaerator system can handle the required volume of water for your processes. The deaerator storage tank should be appropriately sized to provide a continuous supply of deaerated water.
  2. Efficiency: Look for a deaerator system with high efficiency in removing dissolved gases. Advanced designs and technologies can enhance the performance of the system.
  3. Material: The materials used in constructing the deaerator and storage tank should be resistant to corrosion and suitable for the specific chemicals used in your processes.
  4. Maintenance: Choose a system that is easy to maintain and has a track record of reliability. Regular maintenance is essential to ensure the long-term effectiveness of the deaerator system.


The importance of deaeration in the chemical industry cannot be overstated. A well-designed deaerator system, including a deaerator storage tank, is essential for preventing corrosion and ensuring the purity of process chemicals. By investing in an efficient deaerator system, chemical manufacturers can protect their equipment, maintain product quality, and optimize their processes. Safeguarding your processes with deaeration is a critical step towards achieving efficiency, reliability, and excellence in the chemical industry.
