Who has ever done the boiling operation in a coking distillation tower?
Thread Content
In simple terms, in a boiling tower, cold water is introduced through top reflux or cold reflux, while steam is supplied at the bottom for heating; once the hot water overflows from the top to the bottom, the water quality is checked to verify the effectiveness of the boiling tower. It is said to work very well – by opening the manhole, one can enter the tower wearing clean clothes without getting them dirty? Now, both atmospheric distillation columns and vacuum distillation columns are operated in this way! I’m not sure if this will cause any damage to the equipment What are the risks?
It mainly depends on what you use to heat the tower. If water is used for heating, there are generally no problems, but if substances such as saltwater are used to heat the tower frequently, it will affect its efficiency.
I’ve heard of this approach for the first time; here we usually only use steam towers and just control the amount of steam injected
It’s popular these days to boil the tower; this method keeps it clean. I’ll stop working this year to give it a try! I just want to hear about any advanced experiences everyone has!
Pay attention to the steam volume to prevent the tray from being blown over.
Do not use too much steam to prevent the trays from being blown over. The water inflow at the top of the tower should not be too large, to ensure that the backflow at the bottom of the tower can be discharged.
When washing, just apply steam; it’s just hot water after all
How to ensure that the bottom drain can be discharged?

Using alkaline water with a concentration of over 5%, heated to above 70 degrees, a temporary pipeline can be established to create a closed loop; a circulation period of 4 to 8 hours is sufficient, allowing sludge to be discharged from the bottom of the tower. I work in the separation of mixed benzenes, and I use this method for tower cleaning; it’s done every year, so it should be useful to you.
