Macrotek Inc. products

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.

The Macrotek Packed Bed Scrubber is an air pollution control sollution that utilizes a horizontal cross-flow design for high efficient absorption of gases. In the horizontal cross-flow scrubber design, gas flows horizontally while scrubbing liquid flows down through a liquid distribution system. The scrubber includes a random packing section where the absorption of gases occurs. A high efficiency mist eliminator removes entrained liquids. This is an essential step in the overall performance of the pollution control scrubber system. Re-circulating liquid is sprayed vertically down, cross-flow to the gas flow. A regulated amount of reagent is mixed in the re-circulating liquid to maintain a target set-point. The contaminants in the gas react with the selected reagent. The reaction product is carried with other particulates in the re-circulating liquid. An integral sump is located at the base of the packing section, eliminating the need for an external tank.

Macrotek`s high efficiency cyclonic dust collectors are engineered to include specialty design features that provide high efficiency at low pressure drop. Centrifugal force separates suspended particles from the gas for high efficiency gas cleaning. The gas is introduced through the special involute inlet, producing a spiralling motion which directs solids entrained in the gas to the outer wall. The centre core of clean gas is extracted through a concentric outlet tube into a sealed hopper from which it is collected without disrupting internal flow.

Eductors (also known as jet pump ejectors, and venturi pumps) are the most efficient way to pump or move many types of liquids and gases in the petrochemical, process, and power industries. Eductor scrubbers are widely used for tank vent control and applications where fans cannot be used.

There have been many recent improvements in the bioscrubber industry that have made it a more attractive industrial option for treatment of certain odourous gases where the gas flow rate is consistent and steady over extended periods of time, such as waste water treatment plants. Colonies of sulphur-consuming bacteria populate a section of scrubber packing inside the bioscrubber vessel, consuming gases such as H2S and VOC’s as a part of their metabolic function. Bioscrubbers offer a low operating cost method of air pollution control where applicable.

Macrotek offers a full line of mist elimination products for use in removing entrained liquids. Macrotek`s family of mist elimination systems has been engineered to provide the highest levels of operational efficiency in a variety of horizontal and vertical flow applications.

It is essential that many industrial gases be saturated and conditioned. Macrotek’s cross flow humidifier accomplishes this cost effectively by using a series of water dispersion methods and random packing to bring ambient or moderate temperature industrial gases to saturation. A common application for this product is the biofilter industry where moist, humid air is necessary for proper operation.

Macrotek offers steel or alloy stacks designed to the latest ASME code, both as part of our systems or as stand-alone components.

Macrotek offers custom designed intake filters for gas turbines and large blower applications offering reverse pulse-jet and multistage panel filter designs. In conjunction with Intake filters Macrotek also develops custom designed absorptive style splitter silencers for gas turbine intakes.

SULFCAT is an innovative technology that efficiently removes Hydrogen Sulphide (H₂S) from a variety of industrial gas streams, including natural gas deposits and anaerobic processes. The extremely hazardous and corrosive nature of H₂S makes it necessary to scrub the gas from these processes. SULFCAT uses a non-hazardous, regenerative reagent to remove H₂S from industrial gas streams while minimizing operating costs.
