Chlorine (CI2) Scrubber System
What Is Chlorine?
Chlorine (Cl2) is a pale yellow, toxic gas with a strong, suffocating odor. This highly reactive gas is widely used across multiple industries due to its effective disinfecting and bleaching capabilities. It plays a crucial role in disinfecting drinking water, treating wastewater and sanitizing swimming pools. Chlorine is also a vital component in producing plastics such as polyvinyl chloride (PVC), chemical compounds and industrial solvents.
However, despite its widespread use, chlorine is a hazardous substance. Exposure to high levels of chlorine gas can cause respiratory distress, skin irritation and even chemical burns, making it essential to manage chlorine gas emissions carefully.
What Is a Chlorine Gas Scrubber?
A chlorine gas scrubber is a pollution control system that captures and neutralizes chlorine gas from industrial exhaust streams. These systems use chemical absorption, typically with a caustic solution such as sodium hydroxide (NaOH), to convert chlorine into less harmful compounds like sodium hypochlorite (NaOCl) and sodium chloride (NaCl).
The contaminated gas passes through a packed bed within the scrubber, where the chemical reaction occurs, and the neutralized gas is safely released. Chlorine scrubber systems are essential to industrial safety, particularly in facilities where chlorine is a by-product or is used extensively.
In urgent situations, emergency chlorine scrubber systems can be used to rapidly activate and neutralize chlorine gas in the event of a sudden release or leak, providing an extra layer of safety in critical moments.
Benefits of Chlorine Scrubber Systems
MACH Engineering’s scrubber systems offer several key benefits:
- High-efficiency gas removal: Our systems effectively capture and neutralize chlorine gas, promoting compliance with stringent environmental regulations.
- Corrosion-resistant construction: We use materials such as fiberglass-reinforced plastic (FRP) for long-lasting performance in harsh environments.
- Customizable configurations: Each system can be tailored to suit your facility’s operating conditions. Our chlorine scrubber system design process considers factors such as temperature, Cl2 concentration, particulate content and other applicable parameters.
- Multi-stage chemical processes: MACH Engineering’s systems use advanced multi-stage processes to maximize scrubbing efficiency and optimally neutralize harmful gases.
- Improved air quality: Our chlorine scrubber systems enhance air quality in communities near industrial facilities and help to reduce the health risks associated with exposure to chlorine gas.

Frequently Asked Questions About Chlorine Scrubber Systems
Explore these commonly asked questions and answers about Cl2 scrubber systems.
What Is the Best Wet Scrubber for Chlorine Gas Removal?
In many applications, a countercurrent packed bed scrubber using a sodium hydroxide (NaOH) solution is one of the most effective wet scrubber options for chlorine gas removal. NaOH reacts with Cl2 to produce sodium hypochlorite and sodium chloride — both manageable byproducts. This design maximizes gas-liquid contact through a large surface area of internal packing media, helping support reliable, efficient performance when the scrubber is properly sized for factors like Cl2 concentration, gas temperature and flow rate.
How Does a Cl2 Gas Scrubber Work?
A Cl2 scrubber works by drawing chlorine-contaminated gas into a scrubbing tower, where it rises upward through a packed bed while a caustic scrubbing solution flows downward. The gas and liquid meet across the packing media, triggering a chemical reaction that neutralizes the chlorine. The cleaned gas then exits safely through a mist eliminator at the top of the tower.
MACH Engineering’s chlorine scrubber system design process accounts for factors like Cl2 concentration, gas temperature and flow rate to ensure optimal performance for each application.
What Are Some Applications of Chlorine Gas Scrubbers?
Chlorine gas scrubbers are used in facilities that handle, produce, or store Cl2. Common applications include:
- Water and wastewater treatment plants.
- Chemical manufacturing.
- Pulp and paper production.
- Pharmaceutical facilities.
- Semiconductor manufacturing.
- Chlor-alkali processing.
They are also deployed as emergency scrubbers for facilities that store chlorine in bulk, where an accidental release could pose an immediate and serious safety risk to workers and surrounding communities.
Why Is Chlorine Gas Harmful?
Chlorine gas is harmful because it’s highly toxic even at low concentrations. At low exposure levels, it causes eye and nose irritation, sore throat and cough. At higher concentrations, it can lead to respiratory damage, pulmonary edema and fatality. Chlorine is also heavier than air, meaning it sinks and collects in low-lying areas, making enclosed or poorly ventilated spaces especially dangerous in the event of a leak.
What Are the Two Types of Scrubbers?
The two main types of scrubbers are wet scrubbers and dry scrubbers. Wet scrubbers, like a packed bed Cl2 scrubber, use a liquid solution to absorb and neutralize gases. Dry scrubbers use a solid sorbent or spray-dried reagent instead and produce no liquid waste. For reactive gases like chlorine, wet scrubbers are often a strong fit because they support efficient gas absorption and chemical neutralization when properly designed for the application.
