| titleOfInvention | A device and method for decarbonizing nine towers and multi-condition operation of a pyrolysis gasoline hydrogenation unit |
| abstract | The invention belongs to the technical field of pyrolysis gasoline hydrogenation, and discloses a device and a method for multi-mode operation of nine decarbonization towers of a pyrolysis gasoline hydrogenation device. The top extraction pipeline connected to the hydrogenation reaction system is provided with a column top condenser, a reflux tank and a column top pump in sequence; the middle and lower part of the nine decarburization towers are provided with a C8 sideline extraction pipeline and a sideline The gas phase balance port is produced, and the production pipeline of the carbon 8 side line is equipped with a carbon 8 side line production volume control component, a mixer, a carbon 8 product tank, a carbon 8 product pump, a carbon 8 product cooler and a discharge valve; decarbonization The bottom of the nine towers is provided with a tower kettle extraction pipeline, and the tower kettle extraction pipeline is sequentially provided with a tower kettle pump and a carbon nine product cooler, and a reboiler is arranged at the bottom of the nine decarbonization towers. The device and method of the present invention can be applied to the operation of two working conditions, and can not only meet the requirements of product scheme changes from the overall planning, but also save energy to the maximum extent. |
