A real‐time optimization (RTO) system of an acetaldehyde production process is presented in this paper. Data reconciliation with steady state detection and gross error detection, soft sensoring of coarse acetaldehyde concentration, formulation and implementation of yield optimization are discussed in detail. The effect of the RTO system described was validated in an industrial chemical plant, with an average 2.68% increase in yield promotion obtained, which confirms the effectiveness and practicability of the proposed technique.
