Boiling point elevation of coking desulfurization liquid and treatment methods
Thread Content
I have coking desulfurization liquid here, with a feed concentration of 6.3% (mainly containing ammonium hydrosulfide, ammonium sulfide, and ammonium thiocyanate). The project owner wants to use MVR evaporation, but I understand that the boiling point of this desulfurization liquid is quite high, so using MVR evaporation is not feasible. To those of you who are actually operating coking desulfurization liquid treatment units: for the equipment and liquids in use during operation, when the liquid is in a saturated state, what is the boiling point at this point? I hope to get an accurate figure; feel free to leave a message on the site or get in touch – there will be a red envelope reward, as promised.
How is the coking desulfurization liquid handled by everyone? Feel free to discuss it as well; red envelope rewards – we keep our promises!
MVR is not feasible; instead, steam is used for heating to achieve a certain degree of concentration, followed by cooling and crystallization. Shanxi Coking used to have a salt extraction system that worked very well; I’m not sure if it’s still in use
