  • (1) Vent gas shown here is the flow from the total gas to the flare meter, minus the Purges to the flare (FXG and Nitrogen)
    (2) The Flexigas Flare burns only flexigas, a low-emission fuel gas produced in the Flexicoker Unit and used in refinery heaters. A minimum flow of flexigas is required in the flare for purge gas at all times
    and some additional amount for proper pressure control due to the design of the Flexicoker Unit. .
    Emissions from all flexigas burned, whether in process heaters or in the flare, are included under Martinez Refining Company (MRC) Emissions Cap. MRC continues to look for ways to improve overall refinery fuel balance to minimize flexigas flaring.
    (3) The additional NG fuel is added to suplement the low BTU FXG in order to satisfy requirement for combustion zone heating value greater than or equal to 270 BTU/scf
