This study aims to optimize the product mix of butyraldehyde isomer column in #1 butyloctanol unit of Tianjin BohuaYongli Chemical Industry Co., Ltd. Process simulation of the butyraldehyde isomer column was conducted using As-pen Plus. Then, technique modifications to the feed stage and the process pipeline of the butanol isomer column were carried out, and operating parameters of the column were also optimized. When the column restarted, the purity of isobutyraldehyde and n-butyraldehyde reached above 99% and 99.4% respectively. Furthermore, the content of isobutyraldehydein the n-butyraldehyde was less than 0.1%, which meets the requirements of the downstream octanol unit. Therefore, the aim of selec-tive production of isobutanol and isobutyraldehyde was achieved.
