Product Design and Key Advantages
250y ceramic structured packing features a regular, ordered arrangement of corrugated ceramic sheets, typically with a specific surface area of 250 m²/m³, a high porosity of 95%, and a theoretical tray equivalent height (HETP) of ~0.3 meters. These parameters are meticulously designed to maximize gas-liquid contact, ensuring that formaldehyde molecules efficiently interact with the absorption liquid. The ceramic material, usually alumina-based, exhibits exceptional chemical resistance to formaldehyde and other acidic gases, along with high thermal stability (up to 800°C), which is vital for maintaining performance in fluctuating process conditions. Additionally, its mechanical strength minimizes breakage, reducing operational downtime and maintenance costs.
In application, 250y ceramic structured packing is widely used in formaldehyde absorption systems such as absorption towers, scrubbers, and packed columns. For example, in formaldehyde production facilities, it effectively captures formaldehyde gas from reaction exhaust streams, reducing emissions to meet environmental standards. In chemical laboratories and industrial gas treatment units, it removes trace formaldehyde from air or mixed gases, ensuring safe and clean output. Its structured design also promotes uniform fluid distribution, preventing channeling and dead zones that could compromise absorption efficiency. This combination of material durability and structural optimization makes it a preferred choice for formaldehyde absorption processes.
