  • * Natural gas is used for both pilot and purge gas for the refinery flare system, except for the Emergency Flare and East Air Flare (Maintenance) that uses nitrogen as purge gas.
    The flow is determined using an orifice calculation based on the orifice size in the lines and the line pressure upstream of the orifice.

    **** Vent Gas Flow is vent gas to air flares and DCU flare instead of sum of flare header flows
    In the case of an invalid sample, the monthly average was used for composition data
