With more than 80 years of experience, Macrotek Engineering offers a variety of air pollution control systems to suit a broad range of environmental requirements. Using some of the most innovative and effective technologies available in the industry, Macrotek provides cost-efficient applications for industrial air purification. Hydrometallurgical extraction of metals such as Nickel and Cobalt generate emissions of lethal gases such as Hydrogen Sulphide or Hydrogen Chloride. Macrotek has designed and supplied many systems to capture and treat these gases. In most cases the by-product is returned back to the process for reuse. Pyrometallurgical extraction of metals from sulphur containing ores generate large amounts of SO2 and particulate emissions. Macrotek has designed integrated systems to capture particulate and neutralizes SO2. Chemical plants may generate vents containing various contaminants that are unique and site-specific. An experienced engineering team will custom design a system solution that will be specific to the application refining processes.
