Dual-Stage Industrial Gas Scrubber System

Product Description

Frequently Asked Questions “ Two-Stage Scrubber System

1. What is a Two-Stage Scrubber System?
It is an engineered air pollution control system that combines two stages:

• A pre-scrubber for removing particulates

• A main scrubber (wet or packed bed) for treating gaseous pollutants

2. What pollutants can it remove?
The system is designed to remove:

• Dust and fine particulates

• Acidic or basic gases (e.g., SO, HCl, NH)

• Organic vapors and fumes

• Odorous compounds

3. How does the pre-scrubber work?
The pre-scrubber uses high-velocity spray or venturi action to knock down particulates before they reach the gas-phase scrubber.

4. What type of scrubber is used in the second stage?
The second stage typically includes:

• A wet scrubber for water-soluble gases

• Or a packed bed scrubber for enhanced contact between gas and scrubbing liquid

5. What is included in the full system?
The complete setup consists of:

• Pre-scrubber chamber

• Main scrubber unit

• Centrifugal blower or ID fan

• Interconnecting ducting

• Drainage system

• Exhaust stack

6. What materials are used for construction?
Scrubber systems are built using PP, FRP, SS316, or PVC, based on the chemical nature of the gas stream.

7. Where is this system typically used?
It is ideal for:

• Chemical processing units

• Acid/alkali fume extraction

• Pharmaceutical & fertilizer plants

• Metal finishing lines

• Dye & pigment industries

8. Can it be customized for flow rate and gas type?
Yes. Each system is custom-engineered based on:

• Inlet gas volume (CFM)

• Type of pollutants

• Emission standards required

9. How is treated water or waste handled?
Effluent from the scrubber is routed to a neutralization or treatment tank before discharge, as per local pollution control guidelines.

10. Is maintenance easy?
Yes. The system includes access hatches, spray nozzle cleaning ports, and removable demister pads for simplified inspection and servicing.
