Abstract
A method comprising:a) selecting a loading variable from operating variables, the loading variable being directly related to total energy input into the system and equipment constraint of the system;b) selecting a performance specification variable which is required to be kept within a defined target at all times during operation of the system; andc) pairing the performance specification variable with a manipulated variable having a mass/balance relationship to the performance specification which is not the loading variable and;d) controlling the manipulated variable to maintain the performance specification variable with the defined target.
