摘要
A novel active vapor distributor (AVD) was proposed to address the need for vapor split control during dividing wall column (DWC) design and operation. A DWCs energy efficiency can be significantly reduced by a small deviation in the vapor split ratio; therefore, the vapor split ratio needs to be regulated during operation. In the proposed AVD, vapor splitting was implemented by a modified chimney tray with a specially designed cap. The liquid level of the chimney tray on each end side of the dividing wall section could be adjusted to control the vapor flow split. As the proposed AVD adjusts the friction of the vapor flow path efficiently without any mechanical moving parts, it can realize a more reliable operation of a DWC. The performance of the proposed AVD was evaluated, and the results demonstrated its easy implementation and superior ability to regulate vapor flow split during DWC operation.
