Our customers know they can rely on our research capabilities, engineering expertise and high quality products for the up and downstream oil and gas, petroleum, chemical, pharmaceutical and bio-energy industries.
A Flame Arrester is designed to allow the safe flow of gases and liquids while preventing flame transmission.
Flame Arresters are composed of spirally wound metal bands with precisely reproducible flame-quenching gaps. These gaps are adjusted to the ignition transmission capability of explosive vapors.
The FLAMEFILTER® is made of wound metal strips and forms an effective band arrester. This flame-quenching principle is applied in PROTEGO® end-of-line flame arresters and in-line flame arresters.
When a mixture ignites in a gap, the flame spreads towards the unburned mixture. The volume expansion of the burned mixture pre-compresses the unburned mixture and accelerates the flame propagation. Heat dissipation to the large surface of the gap lowers the temperature below the ignition temperature, thus extinguishing the flame.
The gap width and gap length determine the extinguishing effectiveness of the Flame Arrester. A narrower and longer gap extinguishes the flame more effectively, while a wider and shorter gap reduces the pressure loss. Experiments can determine the optimum solution between the two conditions.
In closed containers or tanks containing liquids, effectively managing pressure is crucial. To ensure secure operations, it is vital to have a dependable mechanism for releasing accumulated pressure and compensating for vacuum conditions. PROTEGO® addresses this requirement precisely through our Overpressure and Vacuum Relief Valves. These valves, equipped with weight-loaded or spring-loaded valve pallets, play a crucial role in maintaining optimal pressure levels within tanks.
The PROTEGO® SE/K Floating Roof Drainage Systems are used to drain rainwater from the floating roofs of storage tanks.
PROTEGO® SA/S Floating Suction Units are used in storage tanks with very high purity requirements of the substances, e.g. aviation or fossil fuels.
