Catalytic reaction to cut off the feed fractionator bottom liquid level
Thread Content
In the catalytic reaction, the liquid level at the bottom of the feed distillation tower rises very rapidly – is it because the liquid from above leaks down through the holes in the tray?
After the feed to the reaction vessel is stopped, in fact all of the feed ends up in the distillation tower; it is necessary to increase the flow rate of the slurry discharge promptly to maintain a normal liquid level
The rise in the liquid level of the distillation column after feed is cut off is caused by several factors: 1. After the feed is stopped, the reaction temperature drops significantly, the degree of cracking decreases, and the amount of liquid-phase components increases. 2. After the feed was cut off, the reaction pressure dropped significantly, and liquid leakage occurred during the operation of the distillation tower. 3. After the feed is cut off, standard installations are equipped with an emergency bypass line that directs the raw material directly to the distillation tower.
