Hydrogen Vent Flare Stack Performance
This paper describes the tests that were performed to establish practical limits for a hydrogen vent flare stack operating under adverse weather conditions. The basic components of the vent stack are a flare, molecular seal, flame front generator ignition system, pilots, support skirt, associated piping, valves, and gauges; all assembled and mounted on a concrete pad as shown in Fig. 1. The molecular seal (John Zink Company) is a device to reduce purging requirement and is identified in Fig. 2. It uses the differential molecular weights of gases to form a seal. This is accomplished by bleeding a lighter-than-air gas into an inverted cylinder which is sealed at the upper end. The flare pilot details are shown in Fig. 3.
