The global scrubber system market is poised to witness steady growth in the forthcoming years. These systems are an assorted group of air pollution control devices that remove some particles and gases from exhaust streams. They inject slurry or a dry reagent into a polluted exhaust stream to cleanse acidic gases. Scrubbers are among the principal devices used to control gas emissions, especially acidic gases. They are also used for heat recovery from hot gases by flu-gas condensation and high flows in LED processes, Photovoltaic (PV), or solar. The varied applications are anticipated to bode well for market expansion in near future. The introduction of stern regulations by different governments to control these effects is projected to further drive the market.
Dry and wet are the two major types of scrubber systems. A wet system is used for cleaning fuel gas and air among other gases of numerous pollutants and particles. It works by contacting particulate matter or target compounds with the scrubbing solution. Solutions can be made of water or reagents that precisely target specific compounds. These are widely considered as the best air pollution control systems for gathering both gas and particulates. Wet scrubbers can be sub-divided into venturi, packed bed, and spray scrubber. Increasing demand from the shipping sector to conform to the new gas emission regulations are expected to drive the scrubber system market.
On the other hand, the dry scrubber system does not concentrate flue gas stream treated with moisture, although it is mainly used to eliminate acidic gases from combustible sources. A series of dry reactants are introduced to drain gas at a very high speed. This task is done in three steps, namely, reagent injection, filtering, and gas cooling. They can be segmented further into dry sorbent injectors and dry spray absorbers. Dry scrubbing has been widely accepted as it is environment friendly. The removal of harmful substances from the exhaust gas is imperative as it averts numerous pollutants from being vented into the air. Dry scrubbers are commonly used as compared to their counterparts, mainly because they produce lesser waste material and by-products. Most of the material sprayed in the exhaust is either caught in a filter or seared in the heat.
Developed economies around the world are increasing stringent policies to observe the numerous constituents of air, which, in turn, is anticipated to propel the market growth. Initiatives taken up by the industries to implement scrubber systems to save labor costs on clean-up methods and time can also bode well for product demand. They enhance revenue generation by reducing the time and labor required to clean exhaust systems.
Petrochemicals and Chemicals, marine, oil and gas, pharmaceuticals, and glass are some of the major end-user industries. Other end-users include pulp and paper, food, agriculture, wastewater treatment, mining, and metallurgy. The marine industry is predicted to hold prominent market share over the next few years. Scrubbers is an embodiment in numerous vessels around the globe including ferries, Roll-On/Roll-Off (RO-RO), container ships, Very Large Crude Carriers (VLCCs), and cruise ships as they emit large quantities of sulphur oxide or SOx. Scrubber systems assist shipowners in burning cheaper fuel with a high content of sulphur, while complying with MARPOL regulations.
Leading companies in the scrubber system market are B&W, Alfa Laval, Dupont, CECO, Fuji Electric, Evoqua, GEA, Hamon Research-Cottrell, Wrtsil, KCH, HZI, Tri-Mer, Nederman Mikropuk, Yara Marine, Verantis.
