Why Chlorine Gas Scrubbers Are Essential in Industries
Chlorine gas is a critical industrial chemical used in water treatment, pharmaceuticals, textiles, and chemical manufacturing. But while it serves essential functions, chlorine is also highly toxic. Even a small leak can expose workers and nearby communities to dangerous concentrations, leading to serious health effects, costly fines, and potential shutdowns.
Regulatory authorities such as the Central Pollution Control Board (CPCB), Occupational Safety and Health Administration (OSHA), and Environmental Protection Agency (EPA) have imposed strict limits on chlorine gas emissions. Industries are now under constant pressure to implement effective control measures like a chlorine gas scrubber system to ensure compliance and protect public safety.
Exposure to chlorine gas at levels as low as 1 to 3 parts per million (ppm) can cause eye and respiratory irritation. At 30 ppm, it can lead to fluid buildup in the lungs. Concentrations above 400 ppm are often fatal within 30 minutes. In a 2022 report by the Chemical Safety Board, 85 percent of chlorine-related industrial accidents were traced back to poor or missing gas scrubber systems.
Installing a scrubber chlorine system is no longer optional, it is essential for any facility that handles chlorine gas. These systems work by drawing contaminated air through a chemical solution, typically alkaline, which neutralizes chlorine into a safe, non-toxic compound. In critical situations such as a leak or equipment failure, an emergency chlorine scrubber automatically activates to prevent hazardous exposure and contain the risk.
Key Reasons to Install a Chlorine Gas Scrubber System
Installing a chlorine gas scrubber system is not just about meeting regulations. It is a strategic investment in safety, operational reliability, and environmental responsibility. Whether your facility handles chlorine in chemical processing, water treatment, or pharmaceuticals, a well-designed scrubber system ensures long-term protection and compliance.

Dry Chlorine Scrubber: Water-Free, Low-Maintenance Gas Control
The dry chlorine scrubber is a waterless solution designed for areas where space, infrastructure, or environmental constraints prevent the use of wet systems. This scrubber uses dry chemical media such as impregnated carbon or reactive pellets to absorb and neutralize chlorine gas effectively.
Suitable for small to mid-scale facilities, retrofitting projects, and water-sensitive locations, this system offers operational simplicity with maximum uptime.
Key Features:
- No water required and zero liquid discharge
- Compact, modular design suitable for tight spaces

- Reliable performance in intermittent gas load conditions
Caustic Scrubber for Chlorine Gas: High-Capacity Chemical Absorption
Envigaurd’s caustic scrubber for chlorine gas is built for large-scale operations where chlorine gas must be handled continuously and safely. Using a recirculating sodium hydroxide (NaOH) solution, this system chemically converts chlorine into safe byproducts through the following reaction:
Cl₂ + 2NaOH → NaCl + NaClO + H₂O
This proven process ensures complete neutralization through optimized contact time, packing design, and real-time monitoring.
Cl₂ + 2NaOH → NaCl + NaClO + H₂O
This proven process ensures complete neutralization through optimized contact time, packing design, and real-time monitoring.
Technical Advantages:

- Continuous pH and ORP monitoring for precise control
- Adjustable media dosing based on chlorine concentration
- Optimized retention time for high absorption efficiency
- Designed to meet site-specific airflow and gas load requirements
How Our Chlorine Scrubber Works
Envigaurd’s chlorine scrubber system is engineered to safely capture and neutralize chlorine gas emissions through a multi-stage chemical absorption process. Each system is custom-designed based on gas load, airflow rate, and emission control standards, delivering high-efficiency performance across industrial applications.
Below is a step-by-step walkthrough of a typical chlorine gas scrubber design.
Below is a step-by-step walkthrough of a typical chlorine gas scrubber design.
1. Contaminated Gas Collection
Chlorine-laden air is drawn from the source (such as storage tanks, process reactors, or dosing areas) using a corrosion-resistant blower or induced draft fan. This ensures steady airflow into the scrubber under controlled pressure and volume.
2. Inlet Chamber and Pre-Filtration
Before entering the main scrubber body, the gas stream passes through an inlet demister or pre-filter. This removes large particulates and moisture droplets that could interfere with downstream scrubbing efficiency.
3. Gas–Liquid Contact Zone (Packed Bed Column)
The gas enters a vertical or horizontal packed bed column filled with structured or random packing materials (such as PP, PVC, or ceramic saddles). Simultaneously, a counter-flowing alkaline scrubbing solution (typically sodium hydroxide, NaOH) is sprayed over the packing via spray nozzles.
- The packing media maximizes surface area and turbulence
- Chlorine gas dissolves into the liquid phase and reacts with NaOH
- Chemical reaction: Cl₂ + 2NaOH → NaCl + NaClO + H₂O
4. Mist Elimination (Demister Pad)
As the gas exits the packed bed, it carries fine liquid droplets. A demister pad or mist eliminator captures these droplets to prevent carryover of the scrubbing solution. This ensures dry and clean air is released.
5. Treated Air Discharge
The neutralized air is then safely vented into the atmosphere or directed into a secondary control unit, depending on the regulatory requirements.

Frequently Asked Questions About Chlorine Gas Scrubbers Manufacturer
Dry scrubbers use solid chemical media (such as impregnated carbon or pellets) to absorb and neutralize chlorine gas without using any liquids. They are ideal for areas where water usage is restricted or where maintenance access is limited.
Wet scrubbers use an alkaline liquid solution (typically NaOH) to chemically react with chlorine gas in a packed tower, converting it into harmless salts and water. Wet systems are preferred for high-volume or continuous gas loads.
Emergency chlorine scrubbers are integrated with chlorine gas sensors placed near potential leak sources. When chlorine concentrations exceed a preset threshold, the system automatically activates fans and scrubbers to capture and neutralize the gas, preventing harmful exposure and environmental release.
Chlorine scrubbers are essential in:
- Chemical manufacturing
- Water and wastewater treatment plants
- Pharmaceutical production and laboratories
- Fertilizer and agrochemical industries
- Pulp and paper mills
Swimming pool chemical dosing systems
Any facility using, storing, or transferring chlorine gas should install a compliant scrubber system.
Media replacement frequency depends on the gas load, operating hours, and type of scrubber:
- Dry scrubbers: Typically every 6 to 12 months or based on pressure drop and breakthrough indicators.
Wet scrubbers: Liquid scrubbing solution is monitored continuously and replenished or neutralized as needed, while packing media may last several years.
