DETECTION OF FAULTS WHEN DETERMINING CONCENTRATIONS OF CHEMICAL COMPONENTS IN A DISTILLATION COLUMN |
摘要 |
The invention concerns a method for determining the concentrations of chemical components of a product, in particular air, in a distillation column, said method involving implementing a model for estimating the concentration of the components from measurements carried out by one or a plurality of sensors (41-45, 51-55), said model using an adjustment parameter making it possible to take into consideration operating variations of the column, the method comprising a step which involves detecting the values (200) of said adjustment parameter that are outside a nominal variation range of said parameter in order to diagnose a fault D in one or a plurality of said sensors. |
