Water in gas
Thread Content
A large amount of water often accumulates in the \"tee\" where the horizontal pipe in the coke oven basement meets the lower nozzle (i.e., at the orifice plate), blocking the orifice plate and affecting the proper heating of the coke oven. Where does this water come from? How to solve it?
Due to seasonal changes, it is essential to insulate the basement; that’s one point. Additionally, after preheating, the temperature of the gas should be kept around 40 degrees – it shouldn’t be too high
Agree with the second floor; pay attention to the temperature after preheating the gas in the preheater.
The temperature here after preheating is 35–40 degrees, but there’s still so much water.
It’s likely that the final cooling tower is shut down for maintenance; as a result, the temperature of the gas at the outlet is high. However, after it enters the basement of the coke oven, it cools down, and even when its temperature rises to around 40 degrees, there is still a large amount of water present

The situation in our factory is even worse. I’m not very familiar with the process of coking, and I hope someone with more expertise can tell me what to do if the orifice plate boxes are frequently blocked by tar, and if there is severe dripping from the horizontal pipes. What specific aspects of the coking process will be affected, how should the coking process be carried out, and what measures should be taken regarding recovery?
Apart from the problems on the 7th floor, there is also the issue of excessive steam from the water seals along the path of the gas purification system used for ammonia and benzene removal, as well as the gas returning to the furnace. It can be determined by checking the temperature of the main gas pipeline returning to the furnace. Also, check how the water seal works along the way
