This work presents an industrial case study within Akzo Nobel Chemicals. Dueto the market demand changes, one of the by-products became more expensive,hence more attractive than the main product. However, the current plant designdoes not allow an increase of the by-product production rate at the cost of themain product. To solve this problem we propose an integrated design thatcombines reaction and separation into one reactive divided-wall column(RDWC) that allows 35% savings in capital and 15% savings in energy costs.
