| titleOfInvention | Acetic acid impurity removal evaporation equipment in diketene production |
| abstract | The invention discloses an acetic acid impurity removal evaporation device in diketene production, which comprises: the device comprises a body, a gas-liquid separator and a gas-liquid separator, wherein the body is in a container shape and is used for providing a containing space for raw material acetic acid and providing a conversion space for gasification of the raw material acetic acid; the primary impurity removal device is arranged in the body and is used for removing impurities carried in the acetic acid raw material and impurities generated during vaporization of the acetic acid; a feeding device arranged on the body and used for introducing raw material acetic acid into the body; and the discharging device is arranged on the body and used for guiding the vaporized acetic acid out of the body. The acetic acid impurity removal evaporation equipment introduced by the invention can timely and effectively remove various impurities in the acetic acid gas before the acetic acid gas enters the cracking equipment, and respectively remove various impurities in stages so as to facilitate later impurity recovery. |
