High-Gravity Air Pollution Control Technology
Stable Compliance | Risk Reduction | ESG & Regulatory Alignment
Semiconductor manufacturing processes—such as etching, cleaning, and solvent usage—often generate emissions containing acidic gases, alkaline gases, water-soluble VOCs, and fine particulate matter (PM2.5).
Concord Technology provides integrated air pollution control solutions designed for high-concentration, highly variable, and complex exhaust streams. By applying high-efficiency gas–liquid contact technology, the system effectively removes volatile organic compounds (VOCs), acidic and alkaline gases, and fine particulate matter (PM). This enables facilities to consistently comply with air pollution control regulations while reducing operational and environmental risks.
The solution is characterized by its ability to significantly enhance pollutant absorption and reaction efficiency within a compact footprint. Exhaust gases can be treated within a very short residence time, achieving a balanced performance in treatment efficiency, energy consumption, and long-term operational stability. The system is suitable for both advanced high-tech manufacturing and general industrial applications.
Regulatory Requirements
According to the Air Pollution Control Act, process exhaust gases must be effectively collected and treated prior to discharge. Semiconductor and related manufacturing processes are required to comply with:
-
VOC emission concentration (ppm) limits or removal efficiency requirements
-
Emission standards for acidic gases (such as sulfuric acid, hydrochloric acid, and nitric acid)
Regulatory control trends have gradually shifted from total emission management to real-time, individual exhaust stack (chimney) concentration control. The required reduction efficiency for individual pollutants should reach 96%, or the emission concentration at each exhaust stack should be below 0.3 ppm.
Non-compliance risks include substantial fines, mandatory improvement deadlines, potential production shutdowns, and failure to meet ESG evaluation criteria.
Technical Principles & Overview
High gravity technology leverages high‑speed rotational force to generate centrifugal acceleration within a specialized reactor chamber, creating an intensified gravity field of up to 100G. This powerful environment transforms liquids into fine droplets and thin films, dramatically increasing their surface area and delivering exceptionally efficient gas–liquid mass transfer.
Within the high‑gravity field, volatile compounds can be rapidly stripped from liquid films, while soluble gases and suspended particles are effectively captured—making the system highly suitable for modern industrial emission control.
High gravity technology provides a next‑generation solution for industries facing increasingly stringent environmental regulations. It offers a compact, energy‑efficient, and high‑performance platform for:
