An improved approach to the construction of air cleaning arrangements for carbon anode plants
- HACA-Tech, St. Petersburg (Russian Federation)
Carbon anodes for aluminum production are fabricated with coaltar pitch. When pitch is heated up to 200 C volatiles composed of polynuclear aromatic hydrocarbons (PAH) are emitted. Central ventilation with a scrubber at the exit is the usual way of cleaning the air of the working environment.The existing air-cleaning systems are massive, technically complicated, metal consuming and their efficiency is poor. The duct arrangement from the working area to the scrubber cannot guarantee the required reduction of PAH concentration in the working areas and any failure of the system necessitates interruption of the anode production. An improved concept of air cleaning system which includes the same local equipment based on a plasma chemical method is proposed. Experience has shown that air-cleaning efficiency is improved and energy consumption is reduced. This new concept has the following advantages: simplicity, small size and weight and high reliability. Modules can be installed at the source of gas emission with individual air intake system. Due to the high cleaning efficiency of the system, air can be recirculated in working areas or emitted directly to the atmosphere.
