VERFAHREN ZUR REINIGUNG EINES APPARATES VON ABLAGERUNGEN AUS EINEM VERFAHREN ZUR RÜCKGEWINNUNG VON NMP DURCH EINLEITEN VON HEISSEM WASSER UND RÜHREN |
摘要 |
A process is proposed for cleaning an apparatus to remove deposits from a process for the recovery of purified N-methylpyrrolidone (NMP) by evaporating NMP from a contaminated NMP stream which is obtained in a process for the extractive separation of acetylene from the reaction mixture of a partial oxidation of hydrocarbons after expulsion of the acetylene as a gas, wherein hot water is passed into the apparatus and is stirred. |
