Treatment and reuse of flue gas containing sulfur dioxide
Thread Content
Due to the continuous rise in the price of sulfur dioxide in the market, it has become possible to make effective use of sulfur dioxide in the exhaust gases emitted by chemical enterprises. Recovering sulfur dioxide not only contributes to environmental protection but also enhances economic benefits. Therefore, an adsorption and recovery process for flue gas sulfur dioxide at a reasonable price is worth investing in! My company is in need of a complete set of process equipment for using activated carbon to recover sulfur dioxide; those who are interested can get in touch with me! cgx6181@163.com Last edited by hxx025 on 2008-8-22 11:16 ]
Our company has a new technology called \"ion liquid circulation method for the removal and recovery of SO2 from flue gas\"; this technology enables the production of gaseous SO2 with a purity of 99.5%； After being re-distributed, SO2 enters the sulfuric acid plant to produce sulfuric acid. Currently, both sets of equipment in our company use this method. For the principles and basic introduction, please refer to my post titled “Removal and Recovery of SO2 from Flue Gas via Ionic Liquid Recycling”. Industrial-scale facilities in actual production will be visible in March and April this year! Feel free to contact me if you're interested!
Can sulfur dioxide in flue gas from thermal power generation be recovered and reused?
In principle, SO2 from thermal power plants can be recycled. The key is to examine whether using \"ionic liquids\" is economically viable (the project I am working on is cost-effective, meaning that the investment in the desulfurization system can be recovered through the economic value of the by-products).
What are the current methods for recovering sulfur dioxide? This post was last edited by atkqn0030 on 2008-7-30 06:31.]
Our company is in need of a desulfurization system to remove and recover SO2 from flue gas; those interested can contact Xu Gong at 13787911558
The key factors are the processing capacity, the size of the equipment, and the investment required
Our company has installed several sets of activated carbon adsorption desulfurization equipment, but the results have not been satisfactory; not only are the operating costs high, but the failure rate is also high.
It’s unlikely; I’ve never heard of any project like that
That’s activated carbon; haha, it’s not all about desulfurization after all
Using activated carbon can convert sulfur dioxide in the exhaust gases into dilute sulfuric acid at a concentration of 13–18%. There are many such successful cases abroad; if the original poster is interested, they can get in touch with me :)
There are mainly two ways to utilize sulfur dioxide in flue gas: one is for the production of sulfuric acid, and the other is for the production of sulfur, although the quality of sulfur produced in this way is poor.
The currently more mature approach is to send the flue gas, after dust removal, directly into the conversion tower for conversion and subsequent absorption. I have never heard of the technique mentioned by the original poster; could they explain the principle behind it as well as some examples from China?
