In terms of revenue, the global scrubber systems market is expected to reach USD 3.0 billion by 2028, growing at a CAGR of 12% from 2021 to 2028. The increasing demand to reduce emissions and harmful gasses from chemical industries is the key reason to adopt scrubber systems. Also, rising stringent regulations passed by the government bodies are driving the scrubber system market.

Key Findings

• Under the type segment, the wet scrubber system sub-segment is anticipated to dominate the segment for the scrubber systems market and grow at a CAGR of 13.5%. This is attributed due to the growing size of processing industries and demand for wet scrubbers due to their high efficiency in reducing pollution.   
• The petrochemicals & chemical industry sub-segment is expected to be the fastest-growing segment as the majority of chemical plants emit harmful gases and scrubber systems are a very essential tool for removing these pollutants    
• Asia Pacific is expected to grow at a CAGR of over 16.21% from 2021 to 2028. The increasing industrialization and urbanization in major countries such as India and China are expected to generate huge revenue from the scrubber systems market.
• One of the restraining factors for the scrubber systems market is the high cost of manufacturing and also installation. The cost of manufacturing is lower than that of installation due to its complicated location and transportation.

Some of key players in scrubber systems market include, DuPont, Alfa Laval, Yara Marine, Wärtsilä, B&W, Verantis, Tri-Mer, Nederman Mikropul, KCH, HZI, Hamon Research-Cottrell, Wärtsilä, GEA, and Fuji Electric. For instance, in 2020, Dupont Clean Technologies provides a wet scrubber unit for the Gazpromneft Omsk refinery. The Gazpromneft Omsk Oil Refinery (Omsk) in Siberia, Russia has significantly lowered its air emissions using BELCO® wet scrubbing technology licensed by DuPont Clean Technologies. With an installed capacity of 22.23 MM tons of oil per year, the Omsk Oil Refinery is one of Russia’s leading oil refineries. The BELCO® wet scrubbing technology was installed at Omsk during a fluidized catalytic cracking unit (FCCU) revamp and efficiently removes process impurities from the flue gas emitted by the FCCU thus reducing air emissions well below detection limits.

The term “scrubber” is being referred to pollution control devices which are using liquid to wash unwanted pollutants from a gas stream. Exhaust gas streams are passed inside the scrubber where an alkaline scrubbing material is present to neutralize the acidic nature of the exhaust gasses and remove any particulate matter from the exhaust. The used-up scrubbing material is then collected with wash water which may be stored or disposed of immediately as the effluent. The cleaned exhaust is passed out of the system and into the atmosphere. The scrubbing material is chosen such that specific impurities like SOx or NOx can be removed by suitable chemical reactions. For example, marine scrubbers can be classified into Wet and Dry scrubbers. Dry scrubbers employ solid lime as the alkaline scrubbing material which removes Sulphur Dioxide (SO₂) from exhaust gasses. Wet scrubbers use water that is sprayed into the exhaust gas for the same purpose.

The emerging economies of the Asia Pacific such as India, China, Indonesia, and Thailand are expected to fuel the growth of the scrubber systems market in coming years. In 2020, countries such as India and China in the Asia Pacific region shared the highest GAGR of 13.2%. The reason for the growth of the scrubber systems market is the growing processing industry, lower cost of labor, and major investment made by key manufacturers. Government bodies are passing stringent regulations to control air pollution. For instance, the Indian Government has made it compulsory for using scrubber systems in chemical plants located near cities and oceans. As India and China are developing countries with huge populations these regulations are made strict, due to these factors scrubber market in these countries will gain popularity in the coming years
