Takraf Africa’s showcase air pollution control technologies

TAKRAF Group’s subsidiary TAKRAF Africa recently showcased advanced range of Tenova air environmental technologies at various client symposium in South America.

The events were held in three cities – Lima (Peru), Santiago (Chile) and Belo Horizonte (Brazil) and were entitled “A Focus on Productivity”, with a specific focus on technologies, equipment and solutions aimed at increasing efficiencies.

TAKRAF, part of Tenova, provide integrated solutions to the global mining, bulk material handling and minerals industries.

In addition to supplying the complete range of TAKRAF systems and equipment, TAKRAF Africa is also an acknowledged specialist on the continent’s mining and minerals market for the design and supply of air pollution control systems and equipment, with more than 4,000 systems installed on various operations, over the past 50 years.

Opportunities presented internationally, such as those in the copper, lithium, iron ore and phosphates industries in South America, mean there is considerable potential for TAKRAF Africa air pollution control technologies to be applied beneficially as part of the TAKRAF global offering.

TAKRAF Africa supplies its Tenova air environmental product lines via a comprehensive service, which ranges from initial assessment of current status and problem definition, through development and engineering of customized solutions to project execution and after sales service and support.

TAKRAF Africa’s range of bag house and bag filters includes the Tenova Reverse Pulse Bag Filter for economical collection of dust at high filtration rates.

With collection efficiencies greater than >99.99 %, it can operate 24 hours per day under arduous conditions, and is fully automated and self-cleaning with no internal moving parts. Filter bags are customized to suit the application, while risk to maintenance staff is minimized as inspection and replacement of bags are from the clean-air sides.

The Tenova-Simatek Reverse Jet Bag Filter is available in two low-maintenance models, the 4T for separation of dry and sticky dust particles, and the 3C for large volumes. The collection efficiency of the Tenova-Simatek range of equipment is 99.9 %.

Offering >99.5 % dust collection efficiency in the 1 – 2 micron range, the Tenova Dynamic Heavy Duty Wet Scrubber is ideally suited to general dust collection on medium to high dust loads. This is a low-cost technology in relation to its high dust collection and energy efficiency, and is supplied with a self-cleaning fan, offering low maintenance requirements and water consumption.

The Tenova-ELEX Electrostatic Precipitators, available as both wet and dry versions, are widely applied for the collection of liquid, solids or particulate matter.

The precipitators high collection efficiency when handling high gas volumes and the ability to handle fine and coarse particles mean that emissions are reduced to <20 mg/NM3, while temperatures of up to 450 °C can be accommodated and up to 1,300 °C when gas conditioning is included. The precipitators offer low running and maintenance costs, as well capital savings over other collector types when handling large volumes.

TAKRAF Africa also supplies the DSI range of equipment, including the Tenova DSI Dry Fog Dust Suppression System, the driest form of dust suppression available as only the dust is wetted and not the material.

With a low water consumption of typically less than 0.05 % by weight, the system is ideal for a range of applications, including transfer points, crushing and screening, feeders, truck dump hoppers and material loading/unloading applications.

The Tenova DSI Wind Fencing solution reduces the airborne particulate that accumulates from material handling operations at coal piles, transformer stations, gypsum piles and landfills, by protecting the stockpiles from wind.

The Boiler Emission Abatement (BEA) plant project for Impala Platinum Refineries in Springs, South Africa is a current example of TAKRAF Africa’s expertise in developing integrated diversified solutions to provide a holistic approach to air environmental control.

The plant provides an innovative and comprehensive solution to the reduction of boiler flue gas emissions, including particulate matter, NOx (nitric oxide and nitrogen dioxide) and SOx (sulphur oxides), which, if uncontrolled, pose severe health risk.
