VOCs
(Volatile Organic Compounds)

VOCs(Volatile Organic Compounds)?

  • Volatile Organic Compounds (VOCs) are carcinogenic substances that cause disorders in the nervous system and other organs when inhaled or absorbed through skin contact.

  • Due to their high vapor pressure, they volatilize easily into the atmosphere.

  • They are also primary contributors to unpleasant odors and the formation of ground-level ozone.

VOC and Odor Removal
Adsorption/
Regeneration Process

Activated Carbon Adsorption and Regeneration Process

  • Adsorption occurs due to van der Waals forces between the surface of the activated carbon and the VOC molecules.

  • Activated carbon possesses an immense specific surface area—typically exceeding 1,000m2 and consists of three distinct pore structures: macropores, mesopores, and micropores.

  • Due to the varying sizes of these pores, adsorption occurs sequentially from macropores → mesopores → micropores.

  • The process exhibits powerful VOC gas removal and deodorization efficiency (exceeding 95%)

  • While the initial adsorption rate is very high, it decreases over time, leading to an increase in outlet concentration.

  • This stage is known as the breakthrough point (break point); once this point is passed, efficiency drops sharply.

  • To extend the operational lifespan, a separate regeneration process is required.

Microwave oxidation mechanism

Features of microwave oxidation technology

  • This technology treats VOCs, hazardous gases, and odorous compounds through oxidation and combustion reactions at high temperatures.

  • As a flameless process that does not require auxiliary fuel, it offers the advantage of generating no secondary pollutants.

  • The system features a rapid initial heat-up rate (~200℃/min), allowing for "on-demand" operation only when necessary.

  • Furthermore, the use of high-concentration treatment and localized heating methods enables the miniaturization of the oxidizer unit.

Comparison of Regenerative Thermal Oxidizers (RTOs) and Regenerative Microwave Oxidizers (RMOs)

Category Regenerative Thermal Oxidizer (RTO) Regenerative Microwave Oxidizer (RMO)
Operating Temp. 800~900℃ 800~900℃ (max.1100℃)
Preheating Time Requires several hours to preheat ceramic media. Rapid heating; preheats in minutes to tens of minutes.
Energy Consumption Requires continuous auxiliary fuel for low concentrations. Maintains temperature easily at low to medium concentrations.
Heat Recovery Over 95% heat recovery via ceramic media. Over 70% heat recovery using an economizer.
Equipment Footprint Large installation area due to the combustion chamber. Compact design (1/2 to 1/3 the size) with no separate chamber.
Maintenance High risk of mechanical failure due to rotors and numerous valves. Simple mechanical structure leads to very low maintenance costs.
Primary Applications High-flow, medium-concentration VOCs. Low-to-medium flow VOCs.
