DAP / NPK online exhaust gas detection issues
Thread Content
I would like to ask the experts: which phosphate fertilizer plants in our country have online monitoring devices installed on the exhaust gas scrubbers of their DAP/NPK production units? It mainly measures the concentration of dust, ammonia, and fluoride emitted in exhaust gases. Could everyone please share their experiences? If such a device is installed, I’m curious to know how well it performs. I’ve heard that the exhaust gases contain silica gel; I wonder if such an online device requires frequent cleaning. Could you also let us know which brand this online continuous emission monitoring device is from? Thank you very much; I hope an expert can give some guidance :)
Does no one know? Does China not have such a system at all? Is there not a single phosphate fertilizer plant equipped with online exhaust gas monitoring devices?
Our unit has already been installed; it uses products from Henan Hanwei. There is no need for cleaning, but it keeps breaking down and triggering fault alarms.
Thank you very much for getting in touch. Could you please tell me your company’s name? If that’s not convenient, just leave a message for me. Thank you
I’d like to ask further – are there any new updates? Is enforcement of environmental protection measures in China rather weak?
