In critical sectors such as power generation, metallurgy, and oil refining, the removal of sulfur dioxide (SO2) from industrial combustion flue gases is a paramount environmental responsibility. Mixtec stands at the forefront of this challenge, offering advanced mixing solutions that effectively address SO2 emissions and contribute to cleaner, more sustainable operations.

Mixtec supports a variety of methods to tackle SO2 emissions effectively:

• Wet Scrubbing: Utilizing a slurry of alkaline sorbent, typically limestone or lime, or even seawater, to scrub gases clean of SO2.
• Spray-Dry Scrubbing: Employing similar sorbent slurries in a spray-dry method.
• Wet Sulfuric Acid Process: Recovering sulfur in the form of high-quality sulfuric acid.

These processes rely on alkaline sorbent materials like limestone and hydrated lime slurries, demanding robust and abrasion-resistant mixers capable of enduring the abrasive environment.

Our autoclave-cured, soft natural rubber-lined wet end agitators are designed for longevity and low wear in these harsh conditions. Whether for upstream slurry preparation or downstream absorption processes, Mixtec’s mixers are engineered for optimal performance:

• Efficient Heavy-Duty Impellers: Designed to prevent gypsum scaling and resist corrosion-abrasion media, ensuring high process outcomes.
• Specialized Mechanical Seals: Selected specifically for FGD service, with a seal shutoff device enabling maintenance without disrupting operation.

Beyond SO2 removal, Mixtec excels in sulfuric acid neutralization applications, vital in metallurgical smelters and for managing acid mine drainage. Our experience encompasses the design of lime milk preparation and neutralization mixers tailored to each unique process requirement. A testament to our capability is the extensive mixing system installed at a large acid mine drainage water treatment plant in Germiston, Gauteng, South Africa, featuring 53 specialized Mixtec mixers in a corrosion and abrasion-resistant execution.

Mixtec brings extensive experience to the table in acid neutralization, a crucial step in processes like metallurgical smelters’ wet sulfuric acid process or the treatment of acid mine drainage with milk of lime. Our comprehensive mixing systems, proven in large water treatment plants, are customized for both lime milk preparation and neutralization tasks, offering specialized solutions that ensure efficient, safe, and environmentally compliant operations.
