Dry Scrubbing

MikroPul can offer a turnkey package for the removal of acidic and toxic pollutants from flue gases using dry chemical absorption. An integral reactor provides optimum mass transfer between the raw gas and absorbent. The spent absorbent is collected dry in our pulse-jet Mikro-Pulsaire® dust collector.

Advantages

• Greater than 90% removal in the case of HCl and HF
• Fabric filter assures greater than 99% efficient particulate removal
• Reheating of stack gases is unnecessary-the system operates above the flue gas saturation temperature
• Low waste disposal cost; no wastewater treatment system required
• Dry, environmentally safe product
• Low water consumption
• Low pressure drop
• Minimal maintenance
