Zusammenfassung: | A system and process for intermittently venting combustible gas (c-gas) from a continuous source to the atmosphere are presented. The system may include a c-gas storage tank, an admission valve located upstream of the c-gas storage tank for regulating the flow of c-gas from the continuous source to the storage tank; an inert gas storage tank and an inert gas valve for regulating flow of inert gas to the c-gas storage tank, the inert gas diluting the c-gas within the c-gas storage tank below a flammable level; a vent valve for atmospheric venting located downstream of the c-gas storage tank, and a PIC that opens the vent valve when pressure in the c-gas storage tank reaches a pre-determined PIC vent point. The system may also include an auxiliary system to receive and vent c-gas diluted below the flammable level while the primary admission valve is closed. |
