Chlor-alkali industry

Jiarui FRP manufactures corrosion-resistant fiberglass reinforced plastic (FRP) equipment for chlor-alkali production plants.

Our FRP tanks, process vessels, scrubbers and piping systems are designed to handle aggressive chemical media including sodium hydroxide, hydrochloric acid, sodium hypochlorite and other corrosive substances.

The chlor-alkali industry is one of the most important basic chemical industries worldwide.

During production, equipment is exposed to strong corrosive chemicals, requiring reliable corrosion-resistant materials

Typical chlor-alkali production processes include:

3.Why FRP Is Widely Used in Chlor-Alkali Industry?

Excellent Resistance to Chemical Corrosion

• Chlor-alkali production involves highly corrosive chemicals.
• FRP equipment provides excellent resistance to acids, alkalis and chemical solutions, making it suitable for demanding chemical environments.

Suitable for Acid and Alkali Applications

• With proper resin selection, FRP equipment can be customized for different chlor-alkali applications.

Long Service Life and Lower Maintenance

• FRP helps reduce corrosion-related maintenance and provides stable performance during long-term operation.

Customized Equipment Design

• FRP equipment can be designed according to:

Chlor-alkali production involves highly corrosive chemical media throughout the manufacturing process.
Equipment used in chlor-alkali plants may face continuous exposure to:

Without suitable material selection, equipment corrosion can lead to:

1.Sodium Hydroxide (NaOH) Corrosion Challenges

Sodium hydroxide, also known as caustic soda, is one of the main products of chlor-alkali production.

During storage and transportation, NaOH solutions may affect equipment depending on:

• Concentration
• Temperature
• Operating conditions

FRP tanks are commonly used for NaOH storage because they provide excellent chemical resistance and can be customized according to concentration and temperature requirements.

2. Hydrochloric Acid (HCl) Corrosion Challenges

Hydrochloric acid is another important chemical involved in chlor-alkali processes.

Due to its strong corrosive characteristics, HCl requires reliable storage and handling equipment.

Traditional metal equipment may suffer from:

• Corrosion damage
• Metal ion contamination
• Frequent maintenance

FRP hydrochloric acid tanks provide a corrosion-resistant alternative for acid storage and processing applications.

3.Sodium Hypochlorite (NaClO) and Chlorine Corrosion

Chlorine-related chemicals are widely used in chlor-alkali plants.

Sodium hypochlorite and chlorine-containing environments may create strong oxidation and corrosion conditions.

Equipment used in these areas requires:

FRP equipment is suitable for :

• Sodium hypochlorite storage
• Chlorine gas absorption systems
• Exhaust gas treatment

4.Limitations of Traditional Metal Equipment

Materials such as carbon steel and stainless steel are widely used in industrial equipment.

However, in chlor-alkali applications, they may face limitations due to aggressive chemical environments.

Common problems include:

5.Why FRP Is an Ideal Solution for Chlor-Alkali Industry
