Calculation note: hydrogen generation rates at steady-stateflammable gas concentrations for single-shell tanks

PDF Version Also Available for Download.

Description

This calculation note analyzes headspace concentrations of hydrogen in single shell tanks dependent upon assumed ventilation flow rates provided by the waste tank ventilation system operation or calculated from Standard Hydrogen Monitoring System data. The analyses are based on measured or estimated steady-state hydrogen release rates. Specific analyses include: 1) The hydrogen generation rate at steady- state hydrogen concentrations and 2)The headspace hydrogen concentration as a function of time, as well as the time required to reach 25% and 100% of the Lower Flammability Limit with barometric breathing in the tank.
