The Macrotek Packed Bed Scrubber is an air pullution control sollution that utilizes a vertical counter-current design for high efficient absorption of gases. In the vertical counter-current scrubber design, gas flows upward while scrubbing liquid flows down through banks of sprays. The absorption of gases takes place in the packed tower scrubber's random packing section and scrubbing liquid is introduced in a liquid trough or spray distribution system. A high efficiency mist eliminator removes entrained liquids, an essential step in performance of the packed bed scrubber system. Depending on the application, a regulated amount of reagent is added to the recirculating liquid to react with the pollutant. The reaction product will be carried with other particulates in the re-circulating liquid and exits the system through a controlled blow-down stream. Clean gas exits the top of the vessel.
In addition to extensive uses in air pollution control, the packed tower can serve as a gas and liquid contactor for many process applications and heat transfers

Flue Gas Desulfurization (FGD) involves the removal of sulfur dioxide and other acids from flue gases. Typical sources of acid gases include fossil fuel boilers, waste combustors, and other industrial applications such as refining and smelting. The Macrotek wet and dry FGD systems can achieve over 99% acid removal by using a variety of reagents, including caustic, sodium carbonate, lime and limestone, and waste alkaline solids or liquids.
The severity of these contaminants requires the most advanced removal and treatment technologies. Macrotek has extensive experience in designing systems that will meet and exceed customers` requirements and regulations. In addition, the corrosive nature of these gases requires specific consideration for material selection.
Hydrogen Sulfide is lethal if released. Macrotek is a leader in developing advanced technologies for optimum removal and treatment. Our experience includes many installations using caustic, oxidizing reagents, catalytic and forced oxidation combination, and biofilters. Each application is unique and requires custom solutions.
Control of emissions is often required due to the hazardous nature of the contaminant. Often, control or removal is necessary due to offensive odours. Ammonia, sulfur and other related compounds fall in these categories. Macrotek offers many control technologies to capture ammonia and other odour causing contaminants. Reagents are often used to neutralize and stabilize the by-product.
Specific industrial applications require wet end of pipe treatment for NOx or CO2. Macrotek offers absorbers utilizing various reagents for neutralization of NOx or CO2. NOx scrubbing is particularly suitable in situations where Nitric Acid can be utilized elsewhere in the plant, as it is a scrubbing product. As CO2 regulations become more stringent, methods for reducing emissions are continually being evaluated. Macrotek offers CO2 scrubbing technology which isolates CO2 in a contaminated stream to produce a pure ...
Macrotek Inc. has announced receipt of two major contracts for a hazardous waste treatment service provider in Central Canada.
