Biogas Plants

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 Explosion Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. and pressure Pressure (gauge pressure) Pressure for which the value is equal to the algebraic difference between the absolute pressure and the atmospheric pressure. fluctuations. PROTEGO® solutions are used in gas storage, flares, and CHP units, tailored to operating conditions and standards. Flame Arresters Flame arrester Device fitted to the opening of an enclosure, or to the connecting pipe work of a system of enclosures, and whose intended function is to allow flow but prevent the transmission of a 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 safe operation in challenging dirty and corrosive environments.
