Discussion on heavy smoke emissions from chimneys in sulfur-based acid production
Thread Content
This post was last edited by “Fish in Love with Cats” on October 14, 2019, at 11:31. Based on my personal experience, there are two situations where smoke comes out of the chimney: 1. When white smoke comes out of the chimney, it’s mainly because the moisture content in the flue gas exceeds the standard level (due to leaks of sulfur-heated steam, leakage of water into the flue gas from the waste heat boiler, high- and low-temperature superheaters, or economizers). In the past, there were instances where water leakage into the flue gas from the high-temperature section of an economizer resulted in white smoke being emitted (typo; this post was published a long time ago, SORRY). 2. White smoke coming out of the chimney (which appears slightly bluish under good daylight conditions) is primarily caused by poor conversion processes and inadequate absorption; as a result, the exhaust gas contains excessive amounts of SO2/SO3. I’m not sure what my colleagues think about this; perhaps my wording is incorrect. I would appreciate any different opinions. As a newcomer, I need to keep learning and improving. Thank you!

The problem mentioned by the poster requires a comprehensive approach, addressing both the symptoms and the root causes. It is recommended to adopt an asymptotic approach, gradually upgrading the acid production setup to steadily achieve the goal of long-cycle production.
Nor can all the focus be placed on the tail suction
Agree to go upstairs; there are too many influencing factors, which must be checked and addressed one by one
It seems to be white smoke in all cases; water leakage also results in white smoke
The high content of sulfur-containing organic compounds leads to the formation of water upon combustion, which also causes smoke to be emitted from the exhaust gases
End-of-pipe treatment is quite difficult and unreliable; the key is to address the issue at the system level itself, by analyzing the real root cause of the problem.
I don’t know where the original poster saw chimneys emitting black smoke
It’s been published for a while; I’m only seeing it now. SORRY~ *（Because it was early in the morning, the dormitory was far from the factory area and the light was dim; the smoke seen indeed appeared black. :handshake It has been edited again – water vapor should be white smoke, and if it isn’t absorbed properly, it should take on a slight blue tint.） . .
