How to treat the desulfurization waste liquid from the HPF process in coking plants?
Thread Content
As the title suggests, I would like to ask how people generally handle the desulfurization waste liquid produced by the HPF method? Is it coal blending at the coal yard? ! Extract salt? Produce acid? Please share your opinions based on your own production processes.
How does your company handle this now?
If you have money, produce acid; if not, use a coal yard. There’s so much promotion for salt production – show us your company’s performance records; go and take a look for yourself
It can be used for salt extraction or acid production; find a way to remove the salts from the desulfurization liquid. It shouldn’t keep circulating within the large system, as that is not beneficial for desulfurization
Does your company produce salt or acid? I would like to know whether in China coal is blended directly on-site, or is salt extraction and acid production more common

I’ve never seen acid production; I’ve seen salt extraction many times, and we use the salt extraction process ourselves as well.
Coal blending still needs to rely on the system for high-temperature decomposition. Salt extraction is a bottomless pit; if environmental regulations didn’t impose requirements, few companies would engage in this activity (in the coking industry). We recently upgraded our equipment by using plate and frame filter presses

For that Tai’an Jinta leather bag company, we didn’t investigate the other two; we used a salt-producing manufacturer from Shanxi. Right in Taiyuan
