Control methods for tar production in styrene plants
Thread Content
Methods for controlling the tar production in styrene plants? The forced circulation rate of the pure styrene column reboiler is higher. Are there any other methods to reduce tar content?
Are you referring to the tar in styrene products or the tar production volume?
Is it not the tar from styrene products, but rather the amount of tar obtained from the flash tank in the pure styrene tower? How is this tar content controlled? 2# xj1983220

There is a relation with the inhibitor used in the distillation process; we use DNBP. Are there any other inhibitors?
Control the amount of material flowing from the refined tower to the flash tank so that it isn’t too large; pay attention to the temperature at the bottom of the tower and the temperature in the flash tank
Everyone knows the routine; the key is how much styrene tar you consume per ton Only then can the level be improved
After dehydration, the DNBP inhibitor enters the sewage system, causing the water to turn red; how to address this issue/
Currently, the styrene plant uses a combination of two polymerization inhibitors, which increases styrene production and effectively controls the polymerization process.
