PROTEGO® Solutions for Alcohol Applications
PROTEGO® offers various solutions for the protection of storage tanks for ethanol and other alcohols.
Please note that the solutions presented here are just examples; we work closely with our customers to provide tailored safety solutions for their specific operational needs and to comply with local regulations and standards.
Examples of the protection of free-standing alcohol storage tanks with Emergency Relief Valve
Emergency Relief Valves are required when storage tanks are designed for the so called fire-case and they are not executed with a frangible roof-to-shell connection.
Deflagration Flame Arrester and Emergency Relief Valve
End-of-line Deflagration Flame Arrester PROTEGO® LH/AD
Emergency Relief Valve PROTEGO® ER/VH
Breather Valve and Emergency Relief Valve
Pressure/Vacuum Relief Valve PROTEGO® VD/TS, atmospheric deflagration-proof
Emergency Relief Valve PROTEGO® ER/VH
The PROTEGO® VD/TS with integrated Flame Arrester provides certified explosion protection and flow capacity as well as ease of maintenance
Pressure Relief Valve, Vacuum Relief Valve and Emergency Relief Valve
Deflagration-proof Vacuum Relief Valve PROTEGO® SV/E
Emergency Relief Valve PROTEGO® ER/VH
Pressure Relief Valve PROTEGO® P/EBR-E, deflagration- and endurance burning-proof for alcohols
Endurance burning-proof required depending on local standards and regulations
Examples of the protection of free-standing alcohol storage tanks without Emergency Relief Valve
Other solutions for fire case venting could be a bursting discs or frangible roof-to-shell connection which would replace the requirements for an Emergency Relief Valve.
Deflagration Flame Arrester
Endurance burning proof end-of-line Deflagration Flame Arrester PROTEGO® BE/HR-E for alcohols
Endurance burning-proof required depending on local standards and regulations
Breather Valve
Pressure/Vacuum Relief Valve PROTEGO® VD/TS, atmospheric deflagration-proof
The PROTEGO® VD/TS with integrated Flame Arrester provides certified explosion protection and flow capacity as well as ease of maintenance
Pressure Relief Valve and Vacuum Relief Valve
Pressure Relief Valve PROTEGO® P/EBR-E, deflagration- and endurance burning-proof for alcohols
Deflagration-proof Vacuum Relief Valve PROTEGO® SV/E
Endurance burning proof required depending on local standards and regulations
Examples of the protection of roofed alcohol storage tanks
When protecting storage or process tanks under roof the venting above the roof is highly recomended. Often in-line Flame Arresters are used. The max. possible run-up distance from source of ignition till point of installation of the Flame Arrester (L/D-ratio) is to be observed.
Protection of Stills
Deflagration-proof, end-of-line Deflagration Flame Arrester PROTEGO® LH/AD
Pressure Relief Valve PROTEGO® DZ/E-F and deflagration-proof Vacuum Relief Valve PROTEGO® SV/E
Rapid opening of the Vacuum Valve with PROTEGO® 10% technology provides maximum protection for the still against vacuum collapse.
In-line Detonation Flame Arrester
Protection of roofed spirit receiver vessels with eccentric Detonation Flame Arrester PROTEGO® DA-E-IIB3.
The location of PROTEGO® DA-E is not restricted.
In-line Deflagration Flame Arrester
Protection of roofed spirit receiver vessels with eccentric Deflagration Flame Arrester PROTEGO® FA-E-IIB3 (L/D ratio <=50).
In-line Detonation Arrester, end-of-line Flame Arrester and Vacuum Relief Valve
Deflagration-proof Vacuum Relief Valve PROTEGO® SV/E
Detonation Flame Arrester PROTEGO® DR/ES or PROTEGO® DR/ES-V with integrated Check Valve
The venting line is designed to provide venting to a safe location and is protected with a deflagration proof end-of-line Flame Arrester PROTEGO® LH/AD or an endurance burning proof end-of-line Deflagration Flame Arrester PROTEGO® BE/HR-E for alcohols. Endurance burning-proof required depending on local standards and regulations.
In-line Detonation Arrester, end-of-line Flame Arrester, Vacuum Relief Valve and Emergency Relief Valve
Deflagration-proof Vacuum Relief Valve PROTEGO® SV/E
Detonation Flame Arrester PROTEGO® DR/ES or PROTEGO® DR/ES-V with integrated Check Valve
The venting line is designed to provide venting to a safe location and is protected with a deflagration proof end-of-line Flame Arrester PROTEGO® LH/AD.
In-line Pressure Relief Valve PROTEGO® D/PAL for emergency relief venting.
