The rectification tower is a tower type gas-liquid contact device for rectification. Taking advantage of the fact that each component in the mixture has different volatility, that is, the vapor pressure of each component is different at the same temperature, the light components (low boilers) in the liquid phase are transferred to the gas phase, while the vapor pressures in the gas phase are different. The heavy components (high boilers) are transferred to the liquid phase for separation purposes.
Open tower operation:
Heat the
Rectifying Tower to make it close to the operating temperature; pressurize the tower to meet the normal operating pressure; add raw materials to the tower; open the heat source of the reboiler and each heater, open the top
Condenser and each cooling power to the device; make incremental adjustments to the operating conditions and parameters of the device.
Tower Parking
Gradually reduce the feeding; the steam will not be reduced in a short period of time; correspondingly reduce the amount of heating agent and coolant until it is completely stopped; discharge the liquid stored in the tower; implement the depressurization and cooling of the tower; clean the Distillation Tower with water.
