What are the reasons for the blockage of the air-cooling tubes?
Thread Content
The unconverted oil was sent to the tank area via air cooling; it was found that the temperature increased and the flow rate decreased after air cooling. I suspect the air-cooling tubes are blocked. What could be causing this? How to avoid it.
The unconverted oil has a low freezing point, slow flow rate, many impurities, and ammonia salts
There is a deviation in the flow of polycyclic aromatic hydrocarbons, with a reduced flow rate that leads to blockages; try increasing the amount of heating steam and reducing the size of the louvers
The air-cooling louvers are fully closed; this is how our company operates. But it doesn’t have much effect.
I have never used this method~~~~
I went to the Northeast once; the naphtha air-cooling system got blocked, so we used a blanket to thaw it out. I never would have thought that naphtha could crystallize before.
