Gas Sparging

Gas Sparging Introduction

Have you ever thought about using the exhaust gas from a steel mill to produce acetic acid, beverages, and others things? The process requires dealing with frequent gas flow onto the liquid. The porous sintered meta sparger is a practical and must-have element that can generate airflow evenly and diffuse bubbles of a specific size.

Are you feeling excited to explore more? Go through the article: Gas Sparger to acknowledge details and essential information related to the material’s features.

What is Gas Sparging?

Sparging is a technical term that has two different meanings. First, it indicates a process of injecting Gas into a liquid—for example, carbonated beverages and water treatment. Second, when you spray liquid onto a solid, the act refers to sparging technique—for example, making beer.

On the contrary, Gas sparging, also known as gas flushing, refers to injecting a gas through a diffuser into a liquid phase. The technique is involved in passing finely dispersed gas bubbles through the liquid and is used both in stripping oxygen from liquids and intensifying chemical or biological reactions.

Now that you have a clear idea about gas spaying, it’s time to explore some industrial purposes and why the Gas sparging technique is used. Let’s get started!

Types of Gas Sparger

Sparger is a method that introduces Gas into a fermenter where aeration provides sufficient oxygen for the organism. However, fine bubble aerators are an essential part of operating perfectly.

And in the marketplace, different types of spargers are used for various industrial purposes. Below we mention and describe other sparger functionalities and where it is used. Let’s take a quick look!

Porous Sparger

The gas sparger is made of sintered metal. It is helpful to generate airflow uniquely and diffuse bubbles of a specific size (10-100 times larger than pore size). However, the porous gas sparger is used in lab scale-non-agitated vessels; because it effectively transfers Gas to the liquid.

The surface has millions of tiny pores that produce countless tiny gas bubbles essential for reducing gas consumption and optimizing mass transfer.

Orifice Sparger

It is a perforated pipe used in a small stirred fermenter and keeps the impeller in crosses or rings. Different sizes are available in the marketplace, but the suitable impeller diameter size should be ~¾.

The air holes are drilled on the under surfaces, but the size of the holes should be at least 6mm in diameter. Orifice sparger is mainly used in agitation and out agitation in exceptional cases like yeast manufacture, effluent treatment, and production of SCP.

Nozzle Sparger

The sparger nozzle is also classified as an “open tank heater,” a single open/partially closed pipe used on a large scale. The pipe is positioned centrally below the impeller. Nozzle sparger is popular for its high-velocity power. No air is blocked when air is passed through this pipe, and a lower pressure loss occurs.

However, the condensing steam and heated suction liquid can be perfectly mixed in the diffuser. For offering a quiet operation, the nozzle sparger is the best pick; because of its perfect size bubbles and enhances circulation.

External Sparger

An external sparger (static mixer) is made with porous sintered metal and used in the industrial de-inking facility, but a 10mm impeller diameter is suitable for every function. However, the external sparger is helpful in dissolving Gas into liquid where the time and volume are reduced to ensure perfect mixing.

The most part is to increase the surface area of the Gas, and this sparger ensures fast absorption into the liquid by creating small bubbles.

Combined Sparger Agitator

The sparger agitator supplies air via the hallow agitator shaft, and the air is emitted through holes (discs or blades of the agitator). It is useful to minimize the flow of distribution (mixing and mass transfer). The combined sparger agitator offers unique features for utilizing substrate gasses and energy.

However, energy consumption can be easily minimized if the flow distribution of air is controlled by oxygen. And the dual sparging mode is used for mass production in different food chains.

Amazing Benefits of Porous Sintered Gas Sparging

Porous sintered metal as a gas sparging can preserve the quality and longevity of food products; it helps eliminate undesirable substances and inhibit unwanted chemical reactions with oxygen. Do you want to know why you should use porous sintered metal?

For more details, let’s check out below:

  • Porous sintered metal is useful for breaking the Gas into micron-sized bubbles and increasing the oxygen concentration in the fermentation broth.
  • The technique helps reduce pollution and production costs by up to 30%.
  • Ensure a mild environment for the fermentation broth.
  • Porous sintered metal can reduce gas consumption compared to other gas distribution methods.
  • The metal is also helpful in reducing the disturbance of fermentation broth.
  • Porous gas spargers require less energy than mechanical stirring.
  • Ensure enough oxygen for growth and productivity.
  • Help to achieve the highest conversion rate.
  • Under a particular oxygen concentration, Gas sparging ensures a proportional oxygen supply to the fermented exhaust gas.  
  • Increase gas distribution efficiency and bacterial fermentation efficiency.

How to Choose the Right Gas Sparger?

The spargers are responsible for creating smaller and more bubbles in the fermentation tank that ensure more gas/liquid contact surface area by reducing both time and the amount of Gas in the liquid. However, the sparger has thousands of pores on the surface.

Do porous sintered spargers provide a rugged construction that is temperature and corrosion-resistant? Of course, the perfect metal (porous sintered) provides you with all industrial facilities. Let’s take a look below to explore more about how you can choose the right one:

  1. The suitable diameter or size of the sparger for in-tank or vessel sparging can maintain liquid pressure and temperature equally.
  2. Provide you with actual gascompressor capacity.
  3. You can easily handle the perfect gas exit velocity with the perfect spargers.
  4. Offer you frequent and smooth gas flow into the liquid of the fermentation tank.
  5. From a single-element side-mounted type to cross-tank flanged, all varieties are available.
  6. The spargers should come with various end fittings like (a) type a hex nipple sparger element and (b) type g elements for welding purposes.
  7. The fine bubble propagation will be able to provide maximum surface area for “mass transfer.”

What things need to consider before ordering?

Before choosing or confirming the order of gas sparger, pay attention to some crucial factors, including –

  • Pore size (particles size your industry needs to keep out),
  • Pressure drop (the pressure loss that can be occurred gases or liquids flow through the tank or filter),
  • Temperature range (the final products temperature range),
  • Strength of the sparger to deal with the operation successfully,
  • The flow rate (gas bubbles into liquid) through the filter,
  • Operating fluid flow, etc.

However, to order or confirm buying always prefer to order from ISO certificate and many patent awards certificates companies like Shinkaifilter to avoid poor metals and other manufacturing issues.
