The escape of methane gas from a biogas plant must be prevented. If the gas buffer capacity is not sufficient to collect the biogas produced during planned maintenance work, in the event of a malfunction or in the event of a disaster, a flare installation is the solution to prevent unwanted emissions.
Within 48 hours after the situation where methane is released, the biogas must be burned by a biogas flare. If no fixed biogas flare is available, it must be possible to demonstrate on the basis of a call-off contract that there is an emergency flare on site within 48 hours. When a biogas flare is switched on, the positioning of the biogas flare must meet the safety requirements as stated in NPR7910-1 + C1.
