CADAIR, a recognized leader in innovative environmental solutions, proudly announces the successful completion of a groundbreaking semiconductor waste gas treatment project in Beijing, China. The project addresses critical emissions from automotive-grade power semiconductor production, with a focus on advanced technologies designed to ensure both environmental compliance and cost-efficiency. With an air volume handling capacity of 26,400 cubic meters per hour, the system processes exhaust gases that include key industrial pollutants such as propylene glycol methyl ether acetate (PGMEA), N-methylpyrrolidone (NMP), and NMP.
State-of-the-Art Waste Gas Treatment Process
At the heart of this project is CADAIR’s advanced treatment system, featuring a two-step process utilizing a zeolite rotor and thermal oxidizer. This combination ensures efficient treatment of semiconductor waste gases, minimizing environmental impact and ensuring compliance with stringent local air quality standards.
- Pre-Treatment Phase: The exhaust gas is initially subjected to pre-treatment, where large particles and high-boiling-point substances are removed. This essential step safeguards the integrity of the zeolite rotor, preventing potential damage from harmful contaminants.
- Zeolite Rotor Concentration: The pre-treated exhaust gas is then routed to the zeolite rotor, where the low-concentration, high-volume gas is concentrated up to 18 times. The zeolite rotor works by adsorbing the waste gases onto its surface, reducing the volume and increasing the concentration. This allows for the use of a smaller, more efficient thermal oxidizer, significantly reducing both capital investment and operational costs.
- Thermal Oxidation: Finally, the concentrated exhaust gas enters the thermal oxidizer, where it undergoes high-temperature combustion. The oxidation process transforms harmful volatile organic compounds (VOCs) into benign substances, primarily carbon dioxide (CO₂) and water (H₂O). This process not only destroys pollutants but also minimizes the system’s environmental footprint.
Compliance with Regulatory Standards
This project marks a significant milestone, having successfully passed its final acceptance test. All system performance indicators met the design requirements, ensuring the waste gas treatment process operates efficiently and within the regulatory limits. CADAIR’s solution meets the requirements of the Beijing Electronic Industry Air Pollutant Emission Standard DB 11/1631-2019, ensuring the emission concentration of the treated gas is compliant with local environmental regulations.
The project highlights CADAIR’s commitment to reducing industrial pollution and upholding global sustainability goals through its innovative technologies and adherence to strict regulatory frameworks.
Maximizing Cost-Efficiency and Sustainability
By integrating advanced technologies, CADAIR not only enhances environmental performance but also maximizes cost-efficiency for semiconductor manufacturers. The zeolite rotor significantly reduces the size and operational complexity of the thermal oxidizer, driving down both installation and maintenance costs. This energy-efficient process is designed to meet the growing demand for environmentally responsible manufacturing practices in the semiconductor industry.
CADAIR‘s integrated approach demonstrates the company’s commitment to providing world-class solutions for businesses in need of effective semiconductor waste gas treatment technologies. The project is a prime example of how CADAIR’s solutions contribute to a cleaner, more sustainable future.
