In chemical production, the distillation tower, as the core separation equipment, has frequent failures that can seriously affect production efficiency and product quality. The common failures mainly include the following types:
Liquid flooding is one of the most typical faults, often caused by excessive gas velocity, high liquid load, or blockage of the downcomer, which can lead to the accumulation of liquid phase in the tower and a sudden drop in separation efficiency. It is necessary to reduce the gas-liquid load and clean the blocked area in a timely manner. Abnormal tower pressure is also common, and high tower pressure may be due to excessive feed volume, condenser blockage, or excessive non condensable gas; If the tower pressure is too low, it may be due to small feed volume and system leakage, and it is necessary to adjust parameters and identify leakage points accordingly.
In addition, tray blockage can cause a decrease in mass transfer efficiency, which is often caused by the deposition of solid impurities and the generation of polymers. It is necessary to shut down for cleaning and install filtering devices; Malfunctions in the reboiler and condenser cannot be ignored. Scaling in the reboiler can weaken the heating effect, and leakage in the condenser can contaminate materials. Regular cleaning and maintenance of sealing components are necessary. Strictly controlling parameters and maintaining equipment in daily operations can effectively reduce the occurrence rate of distillation tower failures.

The operation of the distillation tower needs to be controlled throughout the entire process to ensure safety and efficiency. Before driving, it is necessary to thoroughly inspect the sealing and integrity of equipment, pipelines, and instruments. Inert gas should be used to replace the air in flammable material systems to avoid the risk of explosion.
Smooth operation is required during operation: feeding, heating, adjusting reflux ratio and other actions should be slow to prevent large fluctuations in parameters from causing malfunctions; Closely monitor the temperature, pressure, reflux ratio, and liquid level of the tower kettle and tower top. Pressure stability is the core of temperature and component stability, and prevent liquid flooding. Once there is a sudden increase in pressure difference or a decrease in separation efficiency, the gas-liquid load should be immediately reduced.
Operate in sequence when parking, first stop feeding, then heat and reflux the boiler, and finally empty the material; In case of emergencies such as leaks or fires, quickly cut off the feed and heat source. Regularly clean the scaling and blockage of the tray and reboiler, verify the safety valves and instruments, and maintain the stable operation of the equipment from the details.
