APPLICATIONS

Sparging and Stripping

Sparging and stripping are processes used to remove dissolved gases or volatile compounds from liquids, commonly employed in water treatment, chemical processing, and beverage manufacturing. Sparging injects gas into a liquid to create bubbles that remove contaminants, while stripping uses gas to drive off volatile organic compounds. Air is frequently used for its availability and cost-effectiveness, nitrogen for creating an inert atmosphere, carbon dioxide for adjusting carbonation in beverages, and helium for its inert properties and effectiveness in specialized applications. These gases enhance the efficiency and effectiveness of these processes, ensuring the desired purity and quality of the treated liquids.

Sparging and stripping FAQs

Learn more about our Sparging and Stripping gases and services.

What is sparging in industrial applications?

Sparging involves injecting a gas into a liquid to facilitate the removal of dissolved gases or volatile compounds. It is used to purify liquids by transferring contaminants from the liquid phase to the gas phase.

What is stripping in industrial processes?

Stripping is a method used to remove volatile compounds from a liquid by introducing a gas that strips these compounds out of the liquid. This process is commonly used for water treatment, chemical processing, and pollution control.

Which industrial gases are commonly used for sparging and stripping?

Nitrogen is often used due to its inert nature, which prevents unwanted chemical reactions during the sparging or stripping process. It is commonly used to remove oxygen or volatile organic compounds (VOCs) from liquids.

How does carbon dioxide function in sparging and stripping processes?

Carbon dioxide is used in applications where pH control is also required. It can help remove dissolved gases and adjust the acidity of the liquid, making it useful in processes like wastewater treatment and beverage carbonation.

What are the benefits of using industrial gases for sparging and stripping?

Benefits include improved efficiency in removing contaminants, enhanced process control, prevention of oxidation and other unwanted reactions, and the ability to target specific compounds for removal.

What industries commonly use sparging and stripping?

Industries include water and wastewater treatment, food and beverage, pharmaceuticals, chemical manufacturing, and petrochemicals. These processes help in purifying liquids, recovering valuable compounds, and meeting regulatory standards.

How does sparging improve the quality of liquids?

Sparging helps remove unwanted dissolved gases and volatile compounds, improving the purity and quality of liquids. This is essential in industries like pharmaceuticals and food and beverage, where product quality is critical.

How is nitrogen used in sparging and stripping?

Nitrogen is often used due to its inert nature, which prevents unwanted chemical reactions during the sparging or stripping process. It is commonly used to remove oxygen or volatile organic compounds (VOCs) from liquids.
