Description

Technical Field

The C4 raw material hydrogenation stabilization tower is mainly composed of a tower body, a tower plate, a reboiler, a condenser, a reflux system, etc. The working principle of the C4 raw material hydrogenation stabilization tower is based on the principle of distillation. The mixture is separated and purified through the countercurrent contact and mass and heat transfer process of the gas-liquid two phases in the tower.

[0003] The C4 raw material hydrogenation stabilization tower is mainly used for distilling the components in the C4 fraction. The C4 fraction is a hydrocarbon mixture containing four carbon atoms. These components are processed in the hydrogenation stabilization tower. The main purpose is to adjust their composition, improve product quality or meet the needs of subsequent processing. When working, after feeding through the feed port, gas-liquid separation is first carried out, and then the separated gas is condensed and refluxed, and enters the stabilization tower from the reflux inlet for gas-liquid separation again, wherein the main gas-liquid separation is achieved through the tower plates of the stabilization tower. In the prior art, the separation effect of the tower plates in the distillation section is poor, thereby reducing the separation effect of the entire stabilization tower. For this reason, a C4 raw material hydrogenation stabilization tower is proposed. Utility Model Content
