Abstract
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.

A computer-implemented method, comprising:
- determining a flaring volume in conjunction with heat and material balances for each flare header of a flare system comprising a plurality of flare headers, a plurality of relief sources, a flare network monitoring system, and a plurality of flare stacks;
- determining a composition of the flaring volume within each relief source that discharges to a respective flare stack of the plurality of flare stacks;
- determining volumetric flow rates of each relief source from the flare network monitoring system in real time;
- determining, in real time using molar and mass flow for each component of flaring emissions, a molar balance of the flaring emissions of the respective flare stack;
- and
- controlling the flaring volume of a respective flare header of the flare system to reduce the flaring emissions of the respective flare stack.
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
- determining a flaring volume in conjunction with heat and material balances for each flare header of a flare system comprising a plurality of flare headers, a plurality of relief sources, a flare network monitoring system, and a plurality of flare stacks;
- determining a composition of the flaring volume within each relief source that discharges to a respective flare stack of the plurality of flare stacks;
- determining volumetric flow rates of each relief source from the flare network monitoring system in real time;
- determining, in real time using molar and mass flow for each component of flaring emissions, a molar balance of the flaring emissions of the respective flare stack;
- and
- controlling the flaring volume of a respective flare header of the flare system to reduce the flaring emissions of the respective flare stack.
A computer-implemented system, comprising:
- one or more processors;
- and
- a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, the programming instructions instructing the one or more processors to perform operations comprising:
- determining a flaring volume in conjunction with heat and material balances for each flare header of a flare system comprising a plurality of flare headers, a plurality of relief sources, a flare network monitoring system, and a plurality of flare stacks;
- determining a composition of the flaring volume within each relief source that discharges to a respective flare stack of the plurality of flare stacks;
- determining volumetric flow rates of each relief source from the flare network monitoring system in real time;
- determining, in real time using molar and mass flow for each component of flaring emissions, a molar balance of the flaring emissions of the respective flare stack;
- and
- controlling the flaring volume of a respective flare header of the flare system to reduce the flaring emissions of the respective flare stack.
