The comprehensive treatment of atmospheric multi-pollutants refers to the VOCs, NOx, SO in the exhaust gas₂, HCl, O₃Harmful gases, such as heavy metals and dioxins, are collaboratively removed by adsorption or catalytic technology。

Background of air pollutant control

 Technological advantage

(1) Optimize the flue gas treatment process route

(2) Reduce investment and operating costs

(3) Reduce new equipment investment, small footprint

(4) Easy to install and maintain

(5) Multi-pollutant collaborative treatment efficiency is high

Typical application case

Collaborative treatment technology of volatile organic waste gas (VOCs) containing nitrogen/sulfur/chlorine

1. Technical introduction

      Volatile organic waste gas (VOCs) containing nitrogen sources will form a certain concentration of nitrogen oxides (NOx)/sulfur dioxide (SO2)/hydrogen chloride (HCl) in the process of direct or regenerative combustion (or catalytic combustion).，Then it was treated by dry deacidification and selective catalytic reduction (SCR)，Finally achieve the synergistic ultra-low emission of organic waste gas and nitrogen oxides。

2. Technical characteristics

(1) High purification efficiency, VOCs removal rate of more than 99%, NOx removal rate of more than 90%

(2) The application temperature of collaborative treatment technology is broad

(3) Low one-time investment cost and energy saving

(4) Flexible process layout, small footprint

(5) Easy to operate, high degree of automation, safe and reliable operation

3. Process route
