Abstract:

During the start-up of an ethylene plant using propylene heat pump system, the components in the tower were disordered, the reboiler failed, the pressure difference between the reflux tank and the tower was insufficient, and the system heat could not be balanced. The causes of these problems were analyzed, and some improvement measures were put forward correspondingly, so as to ensure the safe and stable operation of the plant.

Key words: ethylene plant, propylene heat pump system, heat balance
