Treatment of desulfurization liquid
Thread Content
How is the desulfurization liquid generated during the gas purification process disposed of? What are your thoughts, gentlemen? ?
I’m not sure which type of desulfurization you’re referring to. The more advanced methods nowadays include low-temperature methanol washing and NHD desulfurization, but from your question it’s clear that you’re not talking about these two methods. So, what type of desulfurization do you use? Can we discuss this again?
Discharging the remaining desulfurization liquid will pollute the environment; many manufacturers mix it into coal piles. Adjust the moisture content of the coal blend. Practice has shown that its impact on coke quality is minimal. This can consume the remaining desulfurization liquid.
I mean PDS is the wet desulfurization method
Our company uses the HPF method for desulfurization. What does HPF mean? ? ?
First, let me talk about HPF: H stands for hydroquinone, P stands for PDS, and F stands for ferrous sulfate – the name being derived from the main components of this desulfurization catalyst. There are currently two viable methods for treating wastewater; one is to incorporate it into the raw coal, while the other involves adding a salt recovery process to recycle the main salt components present in the wastewater. This latter method is already in use at Jinan Iron and Steel Company, with very good results. The benefits associated with recovering these salts after treatment are quite significant (the entire process was developed by a company in Suzhou)
Isn’t desulfurization liquid always recycled after being regenerated? The question posed by the original poster is a bit vague. The commonly used methods for gas desulfurization at present include NHD desulfurization and low-temperature methanol washing; these are all processes that involve absorption, regeneration, and repeated absorption cycles. By \"desulfurization liquid treatment,\" does the poster mean the residue left after filtering and backwashing the desulfurization liquid? If that’s the case, such tasks are usually handled by sewage treatment plants. The poster can look for relevant information in the water treatment forum
