Gas Scrubber – 20 L to 300 L

The Gas Scrubber is a process pollution-control system designed to remove or reduce suitable acidic gases, chemical vapours, fumes and other soluble gaseous contaminants before an exhaust stream is released or sent for further treatment.

The illustrated unit is available in capacities ranging from approximately 20 litres to 300 litres, allowing configurations for laboratory scale-up, pilot plants and industrial process requirements.

The system primarily consists of a scrubbing vessel, packed column, liquid circulation arrangement, process piping, gas inlet/outlet connections and supporting components.

Contaminated gas enters the scrubber and comes into intimate contact with a suitable scrubbing liquid. The packed column provides a large contact surface between the gas and liquid phases, promoting mass transfer and absorption of the targeted contaminants.

Depending on the gas being treated, the scrubbing liquid may be water or another compatible absorption/neutralization solution selected specifically for the process.

After treatment, the cleaned gas exits through the gas outlet, while the scrubbing solution containing absorbed contaminants is collected for suitable treatment, regeneration or disposal.

Working Principle

1. Contaminated Gas Entry

The process gas containing suitable fumes, vapours or gaseous contaminants enters the scrubber through the designated gas inlet.

2. Scrubbing Liquid Distribution

A suitable scrubbing liquid is introduced and distributed over the packed section of the scrubber.

3. Gas-Liquid Contact

The contaminated gas travels through the packed column while the scrubbing liquid flows across the packing.

The packing provides a large effective surface area for contact between the gas and liquid.

4. Contaminant Absorption

Suitable contaminants transfer from the gas phase into the liquid phase through absorption, dissolution or chemical reaction, depending on the selected scrubbing medium.

5. Treated Gas Discharge

After passing through the scrubbing section, the treated gas exits through the outlet for discharge or additional treatment as required.

6. Scrubbing Liquid Collection

The liquid containing absorbed contaminants is collected in the vessel and may be recirculated, treated or replaced according to process requirements.

Packed Column System

High Gas-Liquid Contact

The packed section is an important part of the scrubber because it increases the surface available for contact between the process gas and scrubbing solution.

Appropriate packing can help provide:

• Improved gas-liquid interaction
• Increased mass transfer
• Better contaminant absorption
• More efficient use of scrubbing liquid
• Controlled pressure drop

Technical Specifications

Final column diameter, packing height, gas flow capacity, scrubbing-liquid circulation rate, construction material and operating conditions should be engineered according to the specific gas stream.

Suitable Gas Treatment Applications

Depending on the selected scrubbing solution and system design, a Gas Scrubber can be configured for suitable treatment of:

• Acidic gases
• Chemical vapours
• Process fumes
• Soluble gas contaminants

The correct scrubbing medium and construction material must be selected according to the specific chemical being handled.
