$6 billion scrubber/adsorber market in 2011


Source: The McIlvaine Company

The world market for industrial scrubber, absorber, adsorber, biofilter systems will exceed $6 billion in 2011 and reach $7 billion in 2015. This is the conclusion reached in the continually updated McIlvaine publication Scrubber/Adsorber World Markets.

Scrubber/Absorber/Adsorber/Biofilter Market ($ Millions)

The largest product segment is absorbers which remove acid gases such as HCl, SO2, and HF.  Absorbers, adsorbers and biofilters are used to capture odors and volatile organic compounds. Dry scrubbers including spray driers, sorbent injection and circulating dry scrubbers are used for acid gas removal in competition with absorbers.  Venturi and sump scrubbers are used to remove mechanically generated particulate from crushing, screening, and transfer of bulk solids.

Segmentation by Application ($ Millions)

Incineration including waste-to-energy applications is the largest single market. Outside the U.S. there is a high priority placed on converting municipal waste to energy.  There are frequently both wet and dry scrubbers incorporated in the same system. Wastewater is a growing application as citizens cite odors as their biggest air quality complaint. It is not unusual for a wastewater plant to invest more than $1 million in air pollution control equipment

The hot areas in the “other industries” categories are cement plants and industrial boilers. The recently promulgated U.S. air toxic standards for cement plants will require nearly 100 scrubbers. An Industrial Boiler MACT Standard, expected to be promulgated in February 2011, will require scrubbers for industrial boilers burning coal and biomass.

Expanded World Region Totals

Over one third of the market this year will be in East Asia. China is investing heavily to clean up the emissions from steel and mining operations.  It is building record numbers of wastewater treatment plants and is including odor control equipment on many of them. China produces more than 50 percent of the world’s cement.

These forecasts do not include the scrubbers used on utility coal-fired boilers.  This is a multibillion dollar market and is treated separately in the McIlvaine FGD World Markets report.

    Another system is the Self Contained or Total Containment System. A company by the name of TGO Technologies has developed a totally self-contained containment system that not only protects your employees but the environment as well. Where major engineering and construction are required to install a scrubber system, this is not needed, but it is recommended, to install a total containment system. The cost of a system of this type is close to half the cost of a scrubber system and will take half of the time to install with far less operational training and maintenance. The ChlorTainer, as it is called, is a self-contained system that requires no pumps, scrubbers, fans, or caustic circulation equipment and because of this, very little maintenance. It is defined as passive for purposes of the RMP and meets with Article 80 of the Uniform Fire Code. Containment vs. scrubber Installing the containment vessel is a fairly simple job and requires very little space when compared to a scrubber system. Such a unit can be installed inside a ventilated room or outside with some type of overhead protection and comes equipped with either a permanently placed fixed cylinder loader or a movable port-a-loader. There are multiple door designs available, which can be operated manually, electronically, or pneumatically. The system can be connected to several different safety devices such as SCADA, chlorine detection, or even seismic detection. It features a high-pressure containment vessel into which a 150-pound or a one-ton chlorine gas cylinder is rolled. When the cylinder is loaded, the vessel is sealed. Through a vacuum regulator connected to a failsafe actuator, chlorine is processed from within the vessel. At any time should the cylinder leak, the chlorine gas is contained within the vessel and processed at a normal flow rate. No hazardous waste is ever generated because all of the gas is used. Each vessel is built to withstand the maximum anticipated release pressure of a failed chlorine gas cylinder and is designed for 20 years of service before requiring any repair. The system comes complete with an electronis scale system, rollers, reseating pressure relief valve, a nitrogen gas operated failsafe valve, pressure vacuum gauge, cylinder loading system, rails and rollers. The system does not require backup emergency power to contain a gas release. Elimination of the caustic scrubbing avoids a hazardous waste generation classification and it removes the dangers that are associated with hazardous waste handling.
