Gas tar dust content
Thread Content
May I ask what the levels of tar and dust are after electrostatic capture in each factory? Our factory has just started conducting tests; the level measured after electrostatic capture is only 2 mg/m3. We are using the glass fiber filter membrane method – could there be an error in some step of the process? I would appreciate some advice
There is tar on the sampling tube inserted into the gas pipeline, but only a small amount in the pipeline itself. Is this because of the high pressure and fast flow rate of the gas? The tar content in the gas, as measured using the filter membrane method, is 3.5–4 L per minute; could it be that the tar mist in the gas isn’t able to be released? I hope the expert can provide an answer
Is it because the moisture content in our gas is high? A lot of water comes out from the connection pipe between the sampler and the flow meter; if the water content is high, will the filter membrane give a lower reading for the tar content in the gas? I hope the expert can provide an answer
There’s too much tar in the ammonia solution
If the amount of water droplets and mist in your coke oven gas after electrostatic precipitation is still high, it can be said with certainty that the levels of tar droplets, mist, and dust in the gas after such treatment will not be low. Please carefully examine the actual performance of the electric precipitator in operation, and refer to the numerous posts on the Haichuan forum regarding technologies and equipment for demisting, dust removal, and separation of coke oven gas – these will certainly be useful as a reference for you.
