Abstract

The invention discloses a dividing wall rectifying tower. In the rectifying tower, a spliter plate is arranged along the vertical direction of the tower, and the inner space of the rectifying tower is divided into a tower top combination zone, a dividing wall zone charging side, a dividing wall zone delivery side and a tower bottom combination zone. The rectifying tower also comprises a liquid intermediate section reflux distribution system and a tower bottom rising gas distribution control system. The dividing wall rectifying tower can be used to flexibly adjust liquid reflux distribution ratio and gas distribution ratio at the two sides of the spliter plate of the dividing wall tower, thus achieving an ideal product separation effect.

Description

[0001] technical field

[0002] The invention relates to a novel dividing wall rectification tower.

[0003] Background technique

[0004] Distillation technology is the most widely used unit operation in the chemical industry. Although it has many advantages, it is also a part of high energy consumption and investment in the industrial process. In chemical industry and other industries, its energy consumption accounts for the total energy consumption of the whole process. more than half. Therefore, the thermodynamic efficiency of the rectification column can be improved by designing a new column structure to reduce energy consumption. The most representative one is the dividing wall column, which refers to setting a vertical partition inside the rectification tower to divide the rectification tower into the top section, the bottom section, the feed section and the middle side line separated by the partition There are four main parts in the product extraction section. Ge...
