摘要：A set of data reconciliation method is established on the background of methanol synthesis system.Gross errors of measured data are identified on the basis of the process simulation data, and random errors are reconciled by the improved projection matrix method. Part of the structural parameters of the distillation column are adjusted,and the reconciled data are used to simulate and optimize the steady-state process for the distillation column.Results show that this data reconciliation method can identify the gross errors of the measure data effectively,and the variance of the component molar flow rate in the reconciled data drops generally, indicating a good reconciliation effect.The reliability of the simulation method is verified by comparing the reconciliation data with the data obtained from the steady-state simulation after adjusting equipment parameters.The proposed energy saving measures based on this method can reduce the loss of energy more effectively. Therefore, this data reconciliation method can be applied to data reconciliation of methanol synthesis system.
