#TechTalk – How the Zeolite Concentrator Bundle with RTO (Regenerative Thermal Oxidizer) Drives Innovation in Semiconductor Applications

A zeolite concentrator bundled with a Regenerative Thermal Oxidizer (RTO) is an integrated system designed to reduce volatile organic compound (VOC) emissions from industrial processes. This system efficiently handles large volumes of low-concentration VOC-laden air while minimizing energy consumption. Here’s how it works:

1. Zeolite Concentrator (VOC Concentration Step):

Function: The zeolite concentrator is a rotating system that adsorbs VOCs from a large volume of air and concentrates them into a smaller airflow, increasing their concentration for easier destruction in the RTO.

Structure:

Rotor or Wheel: The zeolite concentrator features a honeycomb structure coated with zeolite, a porous material that adsorbs organic compounds.

Zones: The wheel is divided into three zones:

Adsorption Zone: VOC-laden air passes through, and the zeolite adsorbs VOCs.

Desorption Zone: A smaller, hot air stream desorbs the VOCs, regenerating the zeolite.

Cooling Zone: The zeolite is cooled before returning to the adsorption zone.

Result: This process reduces the air volume entering the RTO while concentrating the VOCs for more efficient destruction.

2. Regenerative Thermal Oxidizer (RTO) (VOC Destruction Step):

Function: The RTO destroys concentrated VOCs through thermal oxidation, converting them into harmless byproducts such as CO₂ and H₂O.

Structure:

Ceramic Heat Exchangers: The RTO contains chambers filled with ceramic media to store and transfer heat.

Burner: Provides additional heat if needed to maintain the oxidation temperature (typically 760-820°C).

Operation:

Pre-heated air enters the combustion chamber from the ceramic media.

VOCs are oxidized at high temperatures.

Clean, hot exhaust passes through another ceramic bed, transferring heat to incoming air.

Result:

The RTO operates efficiently, using minimal fuel due to its regenerative heat recovery design.

Combined Operation:

Low Energy Consumption: The zeolite concentrator reduces the air volume entering the RTO, improving its efficiency by processing a smaller, concentrated stream.

High Destruction Efficiency: The RTO ensures near-complete destruction of VOCs, achieving destruction efficiency of up to 99%.

Scalability: This system is ideal for high-flow, low-VOC facilities like automotive paint booths, chemical plants, or semiconductor manufacturing.

Advantages:

Cost-Effective: Reduced operational costs due to lower air volume and energy-efficient design.

Compact Footprint: The zeolite concentrator minimizes the need for larger oxidizer systems.

Environmental Compliance: Helps meet stringent air pollution regulations.

By combining the zeolite concentrator with an RTO, facilities can efficiently handle VOC emissions, reduce environmental impact, and optimize energy use.
