Reliable Protection for Methane Gas Handling

Ensuring the safety of biogas plants is vital for stable operation and protection. Methane-rich biogas needs engineered protection against explosions and pressure fluctuations. PROTEGO® solutions are used in gas storage, flares, and CHP units, tailored to operating conditions and standards. Flame Arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. and Pressure Relief Devices ensure controlled gas handling, tank breathing, and flashback Flashback Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture. prevention for secure operation.
