Coke oven gas contains a high amount of water
Thread Content
Our company’s gas recovery system operates using the AS process under full negative pressure. When sampling the gas before the scrubber tower, it was found that the gas contained a high amount of water; I’m not sure what the reason for this is.
I’m not sure what the gas collection temperature downstream of the primary cooler in the original poster’s company is; if it is kept below 25 degrees, it’s likely that steam has leaked into the gas pipeline
Analyze whether there are any changes in temperature and pressure of the gas at this stage; if there is a drop in temperature, the increase in pressure is likely due to the precipitation of previously saturated water, otherwise it must be that water from the outside has entered.
Check whether the temperature in the previous stage was too high, preventing the water from cooling down; that’s why there is more water at this stage.
Thank you all! ! ! :victory:
By reducing the gas collection temperature after the primary cooler, the moisture content in the gas naturally decreases
