Selection of measurements necessary to achieve multicomponent mass balances in chemical plant

Abstract

The idea of balance scheme reduction is applied to the problem of multi-component mass balance calculations. The parameters characterizing the plant streams are the total mass flow rate and the concentrations of individual components. Four categories of streams are distinguished according to the distribution of measured and unmeasured parameters. Two algorithms are presented based upon this reduction. Algorithm CLASS is used to classify, i.e. find redundant and determinable parameters, and algorithm CHOICE is used to select the necessary measurements.
