How does gas sparging work?

Sparging involves passing finely dispersed gas bubbles through the liquid. This helps to improve mixing and increase the surface area for gas-liquid mass transfer. Consequently, this technique is not just used to strip oxygen from liquids, but also to intensify chemical and biological reactions.

How do you size a sparger?

Sparger sizing is based on the superficial gas exit velocity from the porous sparger surface, expressed in feet per minute (FPM), calculated from actual cubic feet per minute per square foot of sparger surface area (ACFM/Ft. 2).

What is a sparger used for?

Spargers are an industry tool designed to deliver gas into a column flotation cell or leach tank to ensure that bubbles are dispersed evenly throughout the flotation cell or leach tank.

What is sparger system?

A sparger is an aeration system that is placed on the bottom of the pool directly under the diving board or platform. Air is then released to create a cushion of bubbles for the diver to land in on the water surface. Air is then released to create a cushion of bubbles for the diver to land in on the water surface.

What is the effect of the gas sparger design?

The effect of the gas sparger design was studied. Highly viscous liquid phases produce gas holdup curve similar to the one obtained with “coarse” spargers. The shape of the needle sparger was discussed based on the Ledinegg instability. The flow-regime transition-points were compared with correlations reported in the literature.

What’s the best way to design a sparger?

5 Steps to Designing a Sparger 1 Step 2 2: . Determine the ACFM (actual cubic feet per minute) of gas required to be dispersed into the liquid. No need to… 3 Rely on our expertise during the design phase.. Manufacturers in nearly every industry have come to appreciate the… More

Why are gas spargers made of sintered metal?

The sintered metal spargers provide a rugged construction, are temperature and corrosion resistant and have a larger gas-liquid contact area. These spargers provide a consistent and evenly dispersed gas.

Which is better for sparging gas or liquid?

The sintered metal spargers provide a rugged construction, are temperature and corrosion resistant and have a larger gas-liquid contact area. These spargers provide a consistent and evenly dispersed gas. High efficiency sparging is achieved by fine bubble propagation.
