【Abstract】 For data reconciliation in single reactor , the element balance technique is efficient and accurate. In the case of multi-unit process with chemical reaction, the data reconciliation can be effectively accomplished by means of Crowe’s projection technique. In this paper, a new strategy was proposed for this purpose based on the Simpson’s method and element balance method for the multi-component process with reactor units. Using data from industrial processes, the comparison was made between the new strategy and the Crowe’s projection technique.The results show that the new method gives a more accurate estimation than Crowe’s projection technique and it proves to be an attractive method for data reconciliation of multi-component process with reactions.更多还原
