Are Scrubbers an Applicable Solution for the Marine Industry?

The global scrubber system market is estimated at USD 1,2 billion in 2018 and is projected to grow at a CAGR of 12,8% to reach USD 1,86 billion by 2023. Nowadays the maritime industry is beginning to shift their focus on ways to regulate harmful emissions that are released into the air or sea. In...

What is the Function of Wet Air Scrubbers in Industrial Process?

One of the biggest challenges environmental engineers face is devising new techniques to prevent additional air pollution. The industry is a large contributor to air pollution. Scrubbers are used at coal-burning power plants, asphalt/concrete plants, and a variety of other facilities that emit sulfur dioxides, hydrogen sulfide, and gases with high water solubility. The work...

Biological Scrubbers for Waste Gas Treatment

The starting points for the design of the biological wet air scrubber were low operating costs and energy savings. Such wet air scrubber has low water and energy consumption, as the amount of washing water that is circulated is very low. The system is characterized by clever simplicity. Thus the biological wet air scrubber reduces...

Wet air scrubbers for animal housing systems

Nowadays air emissions from animal housing systems are being examined more closely for ways to mitigate potentially harmful gases. Wet air scrubbers are one way to remove pollutants from air being exhausted from mechanically ventilated buildings. Wet scrubbers use liquid to collect dust or particulate matter (PM) and absorb gases from the air by using...

How Does a Packed Bed Scrubber Work?

A packed bed is a hollow tube, pipe or another vessel that is filled with a packing material. It can be designed with structured packing or this packing can be filled with a small object such as Raschig rings. Packed bed may contain catalyst particles or adsorbents such as zeolite pellets, granular activated carbon, and...

Wet Air Scrubbers for Acid Gas

Acid scrubber technology is one of the methods for air pollution control with the aim to dust control and reduce air pollution caused by various industries. Acid scrubbers adopt wet scrubbers as one of its forms to counter and remove polluted gas emissions into the environment. Acid scrubbers are majorly applied in the manure processing,...

Wet air scrubbers: common reasons for using and problems

What is the lowest cost method of removing the particulate to an allowable emission level? Wet scrubbing usually provides high removal efficiencies as the dust particles are captured in the water droplets. When this happens, the particle size increases, thereby making it easier to remove the dust. A smaller dust particle would be surrounded by...

An overview of types of wet air scrubbers

The main task of any type of scrubber is removing unwanted gases and particulate matter from industrial smokestacks before they enter the atmosphere. The two main types of scrubbers: wet scrubbers and dry scrubbers. These scrubbers can reduce up to 90 percent of emissions that contribute to smog and acid rain. Wet scrubbers are effective...

Wet Air Scrubber Selection for Particulate Removal

Combustible dust explosions must be eliminated as quickly and effectively as possible in any processing facility. All combustible as solids materials may entail a deflagration or explosion hazard in manufacturing and reduction processes of separation into fine particulates. Dust and other similar substances that contain organic materials and different types of metals are explosive. In...

Venturi scrubber as an advanced dust purification technique

Wet air scrubbers remain the main force for the capture and collection of particulates. Particulate scrubbers, often called Venturi scrubbers, are successful in removing particulates from exhaust gases with high efficiency. This type of dust control technology is a part of the group of air pollution controls collectively referred to as “wet scrubbers”. Venturi scrubbers...
