Electronics

The electronics industry continues to grow rapidly and includes the production of displays, semiconductors and printed circuit boards. These sectors generate volatile organic compound (VOC) emissions during processes such as cleaning, degreasing, etching and coating. The chemicals and solvents used can be harmful to the environment and employee health. The industry requires 100% operational reliability for continuous production, placing demanding requirements on emission-control technologies.

Emission control technologies for the electronics industry:

Regenerative Thermal Oxidation (RTO)

RTO is suitable for removing VOCs from exhaust air with low to medium concentrations, which is typical in the electronics industry. The exhaust air passes through a ceramic heat-storage bed into the oxidation chamber, where VOCs are converted into harmless substances at high temperatures. Process heat is recovered and used to preheat the incoming air, improving energy efficiency and reducing operating costs. RTO systems are designed for high operational reliability, which is essential for continuous electronics manufacturing.

Regenerative Catalytic Oxidation (RCO)

RCO is ideal for processes with a defined pollutant composition and low VOC concentrations. The catalyst enables oxidation at lower temperatures, saving energy and preventing undesirable by-products. RCO systems are reliable and suitable for continuous operation, meeting the electronics industry’s requirement for 100% operational availability.

Activated Carbon Adsorber

For large air volumes with low VOC concentrations, an activated carbon adsorber is a cost-effective solution. Activated carbon efficiently captures VOCs and is periodically regenerated, enabling continuous operation with low running costs. Straightforward operation and maintenance contribute to overall plant reliability.

Examples of electronics-industry applications:

Semiconductor manufacturing: Wafer etching and cleaning generate VOCs and other harmful substances. RTO or RCO systems can remove these emissions efficiently and ensure continuous, reliable operation.
Printed circuit board production: Applying solder pastes and protective coatings generates VOC emissions. Activated carbon adsorbers reduce these emissions effectively and improve workplace air quality.
Display manufacturing: Organic solvents used in LCD and OLED production release VOCs. Regenerative thermal oxidation provides high VOC removal efficiency and the reliability required for continuous production.

Benefits of implementing these technologies:

High operational reliability: Our systems are designed for uninterrupted continuous operation.
Compliance with emission limits: Effective VOC reduction supports compliance with stringent statutory and environmental requirements.
Employee health protection: Lower concentrations of harmful substances improve the working environment and workplace safety.
Energy efficiency: Technologies such as RTO and RCO use heat recovery to reduce operating costs and the environmental footprint.

Our experience and expertise enable us to design and implement optimal emission-control solutions for the electronics industry that meet demanding requirements for reliability and efficiency.
