New **standards for exhaust emissions are being implemented – how should existing factories take action to cope?
Thread Content
With increasingly strict environmental regulations, the emissions of SO2 from flue gas used in acid production need to be reduced to 400 mg/nm3. This standard cannot be met by most sulfuric acid plants that are currently in operation. I wonder what measures those working in related fields are taking to address this issue?
It seems that those responsible for setting standards do not have a thorough understanding of sulfuric acid, and some of these standards are not practical
The goal is to phase out a number of old and small-scale devices in order to raise the entry standards for the entire sulfuric acid industry.
Standards should be followed strictly, with an emphasis on their proper implementation. It is necessary to see whether they can be implemented effectively; if so, it is likely that a large number of installations, including some newly installed ones, will need to be shut down and modified.
Hehe, it’s quite difficult for old devices to meet new standards – there are too many factors that can affect conversion rates. To be safe, it’s better to use an exhaust gas recovery system! Personal opinion!
The traditional method remains what it is; 400 is already considered a high figure. This represents progress in society and a commitment to the well-being of the people. Other methods can be used instead of the traditional Tao Tai method
Consider a tail gas recovery system after all. Consider both the applications of by-products and operating costs. Old equipment and small factories had better consider closing down – the investment is too high.
From the perspective of production costs, it is more cost-effective to install desulfurization equipment; after all, the cost of carrying out conversion measures to achieve such low emission levels is too high.
