There is a lot of pressure on the industrial Air Scrubber Manufacturer establishments in Noida as well as the whole of Delhi-NCR to prevent fumes  dust  smells  and hazardous gases from entering the air. One of the best methods to treat contaminated exhaust gases before they are vented into the atmosphere and workplace is through an industrial air scrubber. The Shimi Research Centre offers different types of industrial air pollution control systems.

What Is an Industrial Air Scrubber?

The air scrubber for an industrial process is a pollution control device that serves the purpose of removing any type of contaminants from the exhaust air or process gas. This depends upon the use of the device  which may remove acidic gases  alkaline vapor  chemical fumes  particles  odors  or other types of soluble pollutants.

Wet scrubbers operate on the basis of gas-liquid contact  where the contaminated gas enters the system and comes in contact with the scrubbing liquid  thereby facilitating the transfer of pollutants from the gas phase to the liquid phase.

Why Noida Industries Need Air Scrubbers

Noida has a varied range of industries such as manufacturing industries  laboratories  pharmaceuticals  electronics industry  metal processing industries  and chemical processing industries. Various industries produce emissions and fumes that may be hazardous for workers' health  machine functioning  neighbourhood air pollution  and regulatory standards.

A properly designed air scrubber will assist industries in:

• Avoiding harmful fumes and reducing corrosion effects

• Odor control from emission

• Collecting soluble gas and chemical vapor

• Improving overall plant operation

• Satisfying environmental and occupational requirements

• Protection from corrosion of ducting and nearby equipment

Wet scrubbers have widespread application in chemical manufacturing industry  pharmaceutical industry  metal surface treatment  electroplating  semiconductor manufacture  PCB manufacture  batteries  waste management  laboratories  and petrochemicals industry.

Types of Air Scrubbers

Different pollutants necessitate different designs for the scrubbers. Shimi Research provides different designs to cater to different gas streams  flow rates  and pollutant loads.

Type of Scrubber

Recommended For

Main Advantage

Packed Bed Scrubber

1. Acidic gases  alkaline gases  and soluble chemical fumes

• Gas-liquid contact for absorption is high

Venturi Scrubber

1. Dust  mist  and high particulates in gas stream

• Strong gas-liquid mixing for hard-to-treat emissions

Spray Tower Scrubber

1. Large volume of gas and moderate pollutant load

• Efficient gas cleaning through simple spraying of liquids

CO2 Purification Scrubber

1. CO2 purification and recovery processes

• Suites gas purification needs

In a packed bed scrubber  gas passes through the packing material while scrubbing liquid passes over it  thereby providing a large wet surface area for absorption and reaction. The venturi scrubber has particular relevance for hard-to-treat dust and emission control requirements  and Shimi Research provides such systems.

How a Wet Scrubber Works

Wet scrubbers usually operate in the following manner:

• The contaminated air or process gas enters the scrubber via the inlet duct.

• The air or gas goes through the spray section  packed bed  venturi stage  or other sections where there is a contact between the gas and liquid.

• A recirculating liquid such as water  alkaline mixture  acid mixture  oxidizing agent  or any other appropriate chemical removes or neutralizes the impurities.

• The treated gas passes through the mist eliminator.

• The cleaned air leaves the process through the exhaust stack  while the liquid is disposed off as per the requirements of the process and type of impurities.

For the treatment of acidic gases such as HCl  SO2  HF  and others  an alkaline scrubbing mixture can neutralize the contaminants.

Choosing the Right Scrubber Manufacturer

It is not just about selecting any air scrubber but more of engineering the scrubber around the emission source. The ideal manufacturer would analyze the gas mixture  flow rate  temperature  concentration of contaminants  space available  material properties  and discharge conditions.

Shimi Research Centre has been mentioned as one of the suppliers of cyclone dust collectors  industrial air blowers  and wet scrubbers in India since 2000. Shimi Research Centre offers industrial air scrubbers in several configurations including spray towers  venturi scrubbers  packed bed scrubbers  and CO2 purification scrubbers.

The following criteria should be considered when choosing a supplier in Noida:

• Tailor-made design of the system depending upon the process emissions

• Materials which can withstand corrosion

• Suitable integration of blowers  ducts  and stacks

• Effective circulation and removal of liquid droplets

• Maintenance-friendly design

• Operating instructions

Applications Across Industries

Air scrubbers for industries prove to be quite useful in any case where the exhaust contains gases  fumes  mists  and odor-producing substances. The uses include chemical industries  pharmaceutical industries  metal pickling and surface treating processes  fertilizer factories  battery manufacturing units  waste treatment  incineration  and electronics chemicals processing.

Other industries where they are helpful include laboratories  food processing  wastewater treatment  plastics and polymer manufacture  and metallurgy where acidic vapors or other process emissions are produced.

Conclusion

A good investment for companies based in Noida is that of an efficient industrial air scrubber because this is one way to improve safety and enhance the efficiency of the plant’s operations. For example  if there is a need for a packed bed scrubber for chemical fumes or a venturi scrubber for contaminated exhaust  or a CO2 purification system for your particular application  then you first need to determine the source of emissions.

Shimi Research will help you to select the right equipment for treating industrial gas and fume emissions.
