* Natural gas is used for both pilot and purge gas for the refinery flare system, except for the Emergency Flare 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.
** The purge gas and pilot gas flows at the Ammonia Plant flare are measured by rotameters in the natural
gas and nitrogen lines.
*** The purge gas and pilot gas flows at the 50 Unit flare are measured by flow meters
**** Corrected for seal pot level and pressure data and includes Coker Flare flows from H2S Treatment Skid, which began operating on 10/5/2018.
***** 50 Unit change in flare purge gas to nitrogen
In the case of an invalid sample, the monthly average was used for composition data
