1. A computer-implemented method, comprising:
receiving instantaneous flaring flowrate data from flaring sources of a flare network of a processing facility;
analyzing the instantaneous flaring flowrate data in conjunction with the physical properties of relief sources obtained from a heat and material balance of the processing facility;
determining, using a processing model associated with a relief source type, size, and identifications, a heating value and a molecular weight for each relief source and flare header, wherein the relief sources are connected using a data signal received and processed using the processing model;
generating reports showing average daily heating values and molecular weights for each flare header; and
providing a real-time display to monitor instantaneous heating values and molecular weights for each flare header on a real-time basis.
