Measuring the calorific value of mixed gaseous fuels can be difficult. These complex mixtures of combustible and non-combustible gases and vapors can vary in concentration or composition over time due to changing conditions. Perhaps it is the rate of change or a wide range of water vapor at different process temperatures. Maybe the combustibles vary widely in composition under different process conditions.
Flare stacks are often used to dispose of the waste products from batch chemical processes. Their waste streams may contain many components such as ethylene, propylene, natural gas, mineral spirits, ethyl acetate, ethanol, hydrogen, isobutyl acetate and isobutanol, to name a few. Not only are these streams complex but the production units are often high-volume continuous processes that operate 24 hours, seven days a week. On top of these intense conditions is the fact that you must also meet certain state and federal regulations.
