CLEANER AND SAFER REFINING
Fume treatment is an essential step in PGM refining, focusing on managing and neutralizing hazardous gases and vapors generated during the process. These gases can include volatile organic compounds (VOCs), acidic fumes, and potentially harmful substances. Proper fume treatment helps mitigate environmental impact and ensures the safety of both workers and the surrounding community.
Wet Scrubbers play a crucial role in eliminating compounds, corrosive chemicals, and particulates from exhaust gases before they are released or further processed. Particularly useful for acid gas control and particulate collection, the system’s packed tower scrubbers are designed for chemical contaminant removal from gas streams. This technology handles diverse airflows and materials, ensuring the safe release of clean air. The scrubbers consist of perforated trays within a vertical cylindrical tower, where liquid and gas interact through the tray holes, and gas absorption is facilitated by a foaming effect. After treatment, the gases are either safely released into the environment if they meet regulatory standards or recirculated back into the process if appropriate.
A liquid—usually water—is injected into the waste gas stream. The liquid droplets impact and entrain particles from the exhaust stream, collecting them at the summit to be blown down. The treated air stream is then discharged through the exhaust stack. The selection of absorption liquids depends on the content of the gas mixture. The absorption process is carried out when the polluted gas passes through a washing tower, and particles larger than 1 mm in diameter collide with water droplets or wet surfaces.
Optimum design: Ensures sufficient contact time so that the reaction between the liquid and pollutants is completed.
Special geometry: Provides an extended contact surface, as some reactions can take as long as tens of seconds.
Waste gas treatment units are designed to minimize harmful emissions, contributing to environmental protection and workplace safety. By effectively neutralizing toxic gases, these systems support clean air standards and enable a healthier industrial environment. As an integral part of the refining process, they enhance overall sustainability and ensure compliance with environmental regulations.
