Discussion on the issues of dry quenching of coke
Thread Content
Dry quenching of coke is carried out using carbon dioxide; the principle involves the reaction of carbon dioxide with carbon particles, which not only absorbs heat and reduces temperature but also produces the useful compound CO. It is said that there are projects in operation using this method. I would like to ask everyone about the feasibility of this method?
I’m hearing about this for the first time – how fast is the temperature dropping?
If the carbon dioxide reduction chemical reaction can indeed occur as stated, the cooling rate should be faster than that of heat transfer.
Not considering the risks? :o Carbon dioxide has a high density, so it tends to accumulate at the bottom of the coke discharge system, increasing the risk of accidents.
Can the gas produced be collected in a sealed manner and then fed into a CO combustion boiler to generate steam?
This definitely works; the theory’s proponent also wants to use it for synthesizing chemicals as a carbon source for coke oven gas. :)
It’s a great idea; we just need to consider safety. The dangers of CO!
I wonder if it’s possible to make it completely airtight?
How should carbon dioxide be dealt with when it reacts with coke at high temperatures to produce carbon monoxide? Carbon dioxide has a weaker cooling effect than nitrogen.
