SYSTEM AND METHOD FOR SAFER VENTING OF HYDROGEN OR OTHER COMBUSTIBLE GASES

摘要

A system and process for intermittently venting combustible gas (c-gas) from a continuous source to the atmosphere are presented. The system includes a primary c-gas storage tank (40), at least one primary admission valve (20/30) located upstream of the primary c-gas storage tank (40) for regulating the flow of c-gas from the continuous source to the storage tank (40), a primary valve (50) for atmospheric venting located downstream of the primary c-gas storage tank (40), and a primary PIC (10) that opens the primary valve (50) for atmospheric venting when pressure in the primary c-gas storage tank (40) reaches a pre- determined PIC vent point. The system may include an auxiliary system (60) to receive and vent c-gas while the primary admission valve (20/30) is closed. The primary (5) and auxiliary (60) systems may also include an inert gas storage tank (120/140) and inert gas valve (130/150) for diluting the c-gas before it is vented to the atmosphere.
