VOC treatment in the aerospace sector
An Italian company working in the aerospace industry needed to replace the three old Scrubber systems installed for abatement of gases and vapors produced in surface chemical treatments of metals. The technology of these three installations were obsolete, so they were no longer capable of abating volatile organic compounds generated by galvanic processes and in the nital department.
Problems
- Inadequate air quality, both inside the heat treatment plants and outside.
- Need to replace washing towers that are now obsolete and no longer efficient.
- Presence of VOCs, gases, and vapors generated by galvanic processes and the heat treatment of nital, leading to environmental and safety issues.
Technical features Scrubber
- N° 1 vertical tower with air flow rate: 38.000 m³/h and installed power: 55 kW
- N° 1 vertical tower for acid vapors with air flow rate: 38.000 m³/h
- N° 1 vertical tower for nital with air flow rate: 8.000 m³/h
- Innovative monitoring system, installed power 45 kW and equipped with inverter, touch screen and PLC.
HF supplied and installed VOC abatement systems with complementary interventions, in compliance with regional BAT standards. The project included the installation of a filtration system with three vertical washing towers and the construction of collectors to integrate the old suction line with the new scrubbers. The plant was designed to ensure low pressure losses in the circuit and reduced abrasion, thus guaranteeing greater efficiency and long-term reliability.
- Plant safety improvement.
- Healthy and high-quality air in the heat treatment departments.
- Filtration systems monitored 24/7.
- Optimization of management and maintenance costs.
