Engineered for superior environmental compliance, our scrubbing towers are ideal for applications across chemical, power, and manufacturing industries, ensuring reliable performance and effective air pollution control.

What Is a Scrubbing Tower?

A scrubbing tower, also known as a scrubber or wet scrubber, is an industrial pollution control device used to clean exhaust or flue gases before they are released into the atmosphere. It works by spraying a liquid (usually water or a chemical solution) into the gas stream to remove harmful pollutants such as sulfur dioxide (SO₂), nitrogen oxides (NOₓ), particulate matter, and volatile organic compounds (VOCs). The gas and liquid mix inside the tower, allowing the pollutants to be absorbed or neutralized. Scrubbing towers are commonly used in power plants, chemical factories, and other industrial facilities to meet environmental regulations.

How Scrubbing Towers Work

The operation of a scrubbing tower involves the interaction between contaminated gas and a scrubbing liquid. Typically, the tower is a vertical cylindrical structure with a variety of internal components intended to optimize gas-liquid contact. Below is a detailed explanation of how the scrubbing tower works:
  1. Gas Inlet: Through the gas inlet, the polluted gas is sent into the scrubbing tower. This gas may contain a variety of pollutants such as particulate matter, acids, or toxic gases.
  2. Liquid Spray or Film: Once the gas enters the tower, it comes into contact with a liquid—typically water or a chemical solution. This liquid is sprayed or dripped onto the gas stream through nozzles or other spraying mechanisms inside the tower.
  3. Absorption or Neutralization: Pollutants are either absorbed, dissolved, or chemically neutralized as the gas and liquid contact. For instance, sulfur dioxide can react with a chemical solution like sodium hydroxide to form a neutralized product that can be easily removed.
  4. Gas Flow Direction: To ensure that the gas is properly treated, it is typically directed in a countercurrent or concurrent flow direction with the scrubbing liquid. The countercurrent flow, where the gas flows upward while the liquid flows downward, is particularly effective in maximizing contact between the two phases.
  5. Liquid Collection: The liquid, which now contains the contaminants that were trapped, is collected at the bottom of the scrubbing tower after passing through it. Depending on the design, the liquid may be recirculated for reuse or removed for treatment and disposal.
  6. Clean Gas Exit: After the pollutants have been removed, the clean gas exits the tower through an outlet. The gas is now free from harmful contaminants and can be safely released into the atmosphere, adhering to environmental standards.

Types of Scrubbing Towers Offered by United Heat Exchangers

United Heat Exchangers offers a range of scrubbing towers designed for various industrial applications. Each type of tower is designed to handle specific types of contaminants and operational requirements. Below are the main types of scrubbing towers provided by United Heat Exchangers:

1. Packed Bed Scrubbers

The most widely utilized kind of cleaning tower in enterprises is the packed bed scrubber. They consist of a vertical column filled with packing material, such as ceramic, plastic, or metal. The gas stream is passed through the packed bed, where it comes into contact with the scrubbing liquid. This type of tower is highly efficient in removing gases like sulfur dioxide, ammonia, and other volatile compounds.

Applications:

  • Chemical processing
  • Petrochemical industries
  • Power plants
  • Metal industries

2. Spray Tower Scrubbers

Spray tower scrubbers are designed with spray nozzles that distribute the scrubbing liquid over the gas stream. This type of tower is suitable for situations where high gas flow rates and simple operation are required. Spray towers are often used for the removal of particulate matter and acid gases.

Applications:

  • Power generation
  • Waste incineration plants
  • Cement plants
  • Food and beverage processing

3. Venturi Scrubbers

Venturi scrubbers are designed to create a high-velocity gas flow that forces the gas into direct contact with the scrubbing liquid. This type of scrubbing tower is highly effective for the removal of fine particulate matter, heavy metals, and other pollutants from exhaust gases.

Applications:

  • Industrial cleaning
  • Foundries
  • Steel manufacturing
  • Pharmaceutical industries

4. Tray Scrubbers

Tray scrubbers consist of a series of horizontal trays inside a vertical column. Gas flows through the trays, where it interacts with the scrubbing liquid. This design is particularly suitable for removing liquid-soluble contaminants and is often used in industries dealing with volatile organic compounds (VOCs).

Applications:

  • Chemical plants
  • Oil refineries
  • Textile industries
  • Pharmaceutical manufacturing
