Coke oven gas pipeline
Thread Content
In coke oven gas pipelines where wet dust removal is used, the gas temperature is 23 degrees Celsius; large amounts of tar, naphthalene, and other substances adhere to the pipe walls, causing the pipe diameter to shrink. This severely affects the gas pressure and flow rate at the user end. What are some cost-effective measures that can be taken to address this issue?
Wet dust removal for coke oven gas too? Heard about it for the first time
When the gas is cooled to 23 degrees, a large amount of tar settles out; washing it with ammonia water at around 85 degrees can solve this problem. I’ve heard of gas pipelines for wet dust removal for the first time; I guess what you’re referring to are gas pipelines for coke ovens.
Our company usually uses a temperature of around 150 degrees and a pressure of 0.2 MPa to purge the pipelines, and the results are fairly good.
It is better to use steam at around 150 degrees for purging
