Abstract
Systems and methods presented herein generally relate to determining flaring efficiency of a flare based at least in part on radiant or thermal heat generated by the flare that is detected by one or more flare monitors. In particular, in certain embodiments, a control system may be used to determine a flaring efficiency of the combustion of the flare gas at the tip of the flare based at least in part on the radiant or thermal heat detected by the one or more flare monitors.
Claims14
A flare monitoring system, comprising:
- a flaring system of an oil and gas worksite comprising a flare configured to combust a flare gas at a tip of the flare;
- one or more flare monitors configured to detect radiant or thermal heat generated by the combustion of the flare gas at the tip of the flare;
- and
- a control system configured to:
- determine a flaring efficiency of the combustion of the flare gas at the tip of the flare based at least in part on the detected radiant or thermal heat;
- determine a measured flaring temperature of the combustion of the flare gas at the tip of the flare based at least in part on the radiant or thermal heat detected by the one or more flare monitors;
- determine a theoretical flaring temperature of the combustion of the flare gas at the tip of the flare based at least in part on parameters of the flaring system using a simulation model of the flaring system;
- determine the flaring efficiency of the combustion of the flare gas at the tip of the flare by comparing the measured flaring temperature to the theoretical flaring temperature;
- iteratively adjust a first theoretical fraction of the flare gas that is combusted at the tip of the flare and a second theoretical fraction of the flare gas that is not combusted at the tip of the flare based on the comparison of the measured flaring temperature to the theoretical flaring temperature;
- and
- iteratively determine the theoretical flaring temperature of the combustion of the flare gas at the tip of the flare based at least in part on the first and second theoretical fractions of the flare gas.
