Original abstract

This paper describes modelling of consequences of biogas leakage from a gasholder on agricultural biogas station. Four scenarios were selected for the purpose of this work. A rupture of gasholders membrane and instantaneous explosion of gas cloud, blast of gas with delay, emptying of whole volume of gas (without initiation) and initiation of gas with Jet-Fire. Leakage of gas is modelled by special software and consequences are determined on the basis of results. The first scenario was modelled with help of equations because used software does not include an appropriate model. A farm with high building density was chosen as a model case. Biogas is replaced by methane because used software does not support modelling of dispersion of mixtures. From this viewpoint, a conservative approach is applied because biogas contains “only” approximately 60% of methane (in dependence on technology and processed material).

Tento příspěvek popisuje modelování následků úniku bioplynu ze zásobníku na zemědělské bioplynové stanici. Pro účely této práce byly vybrány čtyři scénáře. Porušení membrány plynojemu a okamžitý výbuch plynového mraku, výbuch plynu se zpožděním, vyprázdnění celého objemu plynu (bez iniciace) a únik plynu s iniciací Jet-Fire. Únik plynu je modelován softwarem a důsledky jsou stanoveny na základě výsledků. První scénář byl modelován pomocí rovnic, protože použitý software neobsahuje vhodný model.
