Can online sulfur exhaust analyzers pass domestic regulations?
Thread Content
We have newly installed a sulfur recovery unit with an annual capacity of 10,000 tons. I would like to ask whether online exhaust gas analyzers are available in China that meet the required standards. What about burners for combustion furnaces/incinerators in China? Could you provide specific manufacturers? Thank you!
Generally, foreign ones are used; they are just more expensive
The furnace can be domestic, but the burner needs to be imported. The analyzers are also imported. I really don’t know how it is in China; this is worth paying attention to, and I need to keep an eye on this topic in the future.
Imported components are used for the key parts, while domestic alternatives can be used for the remaining spare parts.
Using domestic analyzers is less accurate, safe, and reliable than manual analysis! ! !
It doesn’t matter whether domestic online analyzers meet the standards or not; the key question is whether they are necessary or not In our province, the environmental protection agency mandates that all sulfuric acid manufacturers install online analyzers. The amount of sulfur dioxide in the exhaust gases can be transmitted to the environmental protection agency via radio waves, allowing them to keep a clear track of the sulfur dioxide emissions from these factories. This poses significant difficulties for some older factories, as they must shut down immediately if their emissions are not up to standard. The EPA claims that the online analysis meets the requirements. What should the sulfuric acid plant do in this situation?
Which foreign company’s wire analysis equipment is better? Does anyone have any information related to online analysis equipment? I’d like to learn about it, thank you
Interfere with radio waves electronically! ! ! :lol :lol :lol
They upstairs are asking for exhaust gas analysis instruments, but in many places in China such instruments still cannot meet the required standards; for example, the calibration standards used for these instruments are not accurate, and most of them come from abroad. I can provide analysis instruments from North America for your reference. Moreover, we can offer comprehensive technical services for desulfurization projects, including full calibration of Claus units and the associated exhaust gas treatment facilities. Get in touch with me!:lol :lol
Domestically, Hangzhou Focus Technology is used; American technology
If all the in-line exhaust gas analyzers used in China passed the tests, then most of the sulfuric acid manufacturers in the country would have to close down, and we would all lose our jobs: lol
Currently, many nozzles and online analyzers used in refineries are imported, as domestic technology is not yet mature. Many of the instruments, control valves, and orifice plates used in our facilities are also imported; in these areas, China is far behind foreign countries.
The online H2S/SO2 ratio analyzer in sulfur recovery units plays a very critical role in ensuring the stable operation of these units. At present, most units in China use those manufactured by the American company AMETEK, but they are relatively expensive. If the device does not burn ammonia, using a domestic burner is also an option ； However, in the case of ammonia combustion, it is better to use imported nozzles with strong mixing and premixing capabilities (the ones that are widely used in China and perform well are those from Dutch company DUIKER and Canadian company AECEMETRIC).
What to do if there is a shortage of staff, and real-time monitoring online is not possible either?
