Emergency pressure relief stack with endurance-burning-proof pressure and vacuum relief valve VD/SV-HRL (→ Volume 7)

Gasholder with detonation flame arrester DR/SBW (→ Volume 4) in the gas supply and end-of-line deflagration flame arrester BE/HR (→ Volume 2), which protects against endurance burning, above the diaphragm

Temperature-monitored deflagration flame arresters FA-I-T (→ Volume 3) in the feed line for vapour combustion at the maximum allowable distance from the ignition source and in parallel for the sake of availability for servicing or emergency switching in case of an endurance burning on the arrester Vapour pipeline from plant to vapour combustion unit with deflagration flame arrester FA-I-T (→ Volume 3) to protect the vent header collection line and the operating locations in the plant.
