| titleOfInvention | Device for extracting high-purity thiophene from crude and pure benzene |
| abstract | The utility model discloses a device for extracting high-purity thiophene from crude and pure benzene, which comprises a connecting pipe and a separation tower, wherein the primary distillation tower is divided into a tower top, a tower middle part and a tower bottom; the tower top is sequentially communicated with the condenser, the tower top reflux tank and the tower top reflux pump through the connecting pipe and returns to the tower top; the tower bottom is connected with the reboiler through the connecting pipe and returns to the tower bottom; the tower bottom is sequentially connected with the tower bottom pump III and the detergent tank II through the connecting pipe; the method improves the efficiency of extracting high-purity thiophene from crude and pure benzene and reduces the energy consumption of a production system by changing the original rectification separation system. |
