Systems and methods include a computer-implemented method for monitoring emissions in real time. Flaring emissions are determined in real time for a flare stack based on: 1) a flaring volume in conjunction with heat and material balances of systems that discharge to a flare system, and 2) a composition of each relief source that discharges to the flare system. A molar balance around the flare stack is performed in real time using the flaring emissions to determine the emissions.

Methods and systems of burning a multi-phase hydrocarbon fluid include determining a water content of the multi-phase hydrocarbon fluid, communicating the multiphase hydrocarbon fluid to a fuel port of a burner in a primary fuel flow, initiating a flame at the burner to combust the multi-phase hydrocarbon fluid, communicating an auxiliary fuel source to the burner fuel port in an auxiliary fuel flow, and controlling the primary and auxiliary fuel flows based on the water content of the multi-phase hydrocarbon fluid.

An emission control flare stack for minimizing the formation of volatile organic compounds wherein the stack has a controller for operating a gas flow meter; a inlet gas regulator; an oxygen/air flow meter; an oxygen/air regulator; a burner with at least one igniter; a plurality of cooling and heating tubes; and a neutralization solution regulator. The controller receives data from a temperature sensor and an emissions sensor and is in communication with a network. The controller provides controlled burn and neutralization using air intake information and gas concentrations information and can transmit data to an administrative server, cloud computing processor, client devices or combinations thereof for continuous remote viewing of emissions using an executive dashboard.
