Sparging is the process of adding gas as fine bubbles to a process liquid in order to increase the rate of biological or chemical reaction by improving the available surface area between the two phases. Stripping is the process of adding gas as fine bubbles to a process liquid in order to adsorb a component from the liquid.
Carbon dioxide is used in sparging applications such as waste water pH control, and Linde's patented pulp washing technology. Nitrogen is used in stripping applications such as removing oxygen from oil or waste water to promote anaerobic activity, or in sparging applications such as wine production.
Linde's proprietary fine bubble diffusion sparger allows one to introduce gas into their process with the convenience and flexibility of being able to remove the sparger from the process at any time without bringing the process down. |
