How can the high-temperature tar vapor from waste gas be captured?
Thread Content
Considering the waste gas from coke ovens, tar exists in vapor form at high temperatures. It is now desired to recover the waste heat from this gas, but when its temperature drops below 360°C, the tar vapor begins to condense and adheres to the outer walls of the heat exchanger. Is there any suitable equipment that can capture this tar while it is still in a gaseous state at high temperatures? ! Please give me some advice
I think there must be specialized matching equipment or processes for this. One only needs to find the right path to enter the right door. Good luck to you.
Isn’t the electrostatic precipitator meant for exactly this purpose?
However, generally, ammonia is used to spray most of the tar first, and electrostatic precipitation is used to handle a small amount of the tar
It cannot be washed with ammonia; doing so will lower the temperature of the waste gas, making it impossible to recover the waste heat. All my thoughts are on effectively recovering tar vapor without significantly affecting the temperature of the waste gas.

Electrostatic precipitators capture oil droplets in gases, and raw gas contains a large amount of tar vapor; without cooling, it is difficult for the tar to condense into droplets, so there is no effective way to remove it
1MPa steam can be generated.
I don’t understand; how do I get the tar drops out?
