Seeking advice on exhaust gas treatment and collection coverage plan

LZ, this question is too broad – be more specific! ! ! Organic waste gas, flue gas from coal-fired boilers, flue gas from catalytic regeneration, exhaust gas from double desulfurization.....................I don’t know how to answer you! ! !

To the best of my knowledge, a brief summary of different waste gas treatment solutions is provided below; everyone is welcome to share their feedback. Organic waste gases: Biological treatment methods and absorbent absorption methods are used; the substances to be treated include organic malodorous compounds such as thiol, thioether, and dimethyldisulfide, as well as the inorganic malodorous gas hydrogen sulfide. Of course, some facilities opt for combustion methods. Acidic gases: This is something well-known in the petrochemical industry, where comprehensive utilization to produce chemical products such as sulfur or sulfides is the preferred approach. Discuss in more detail the treatment of cold coker water and large-scale purge exhaust gas in delayed coking units. Currently, a closed treatment process is generally employed; for large-scale gas blowing, systems such as vent towers and air cooling are used for treatment, while cold coking water is typically treated through closed oil removal, dust removal, and air cooling. Flue gas from coal-fired boilers: Conventional flue gas desulfurization and dust removal methods are sufficient for this purpose, including dry and wet methods. Catalytic flue gas: This type of waste gas seems to be quite problematic; due to the high temperatures, large amounts of dust, various types of pollutants, and high concentrations, it is difficult to handle. I’ve said a lot, but it seems there isn’t much substantial content. I hope everyone will contribute more and engage in more discussions, so we can all learn together; this is just an attempt to spark further discussion! ! ! As a supplementary note: Oil tank breathing emissions and volatilization during loading generate oil vapors; generally, activated carbon adsorption, membrane filtration, solvent extraction, and condensation recovery processes are used. Each of these four processes has its own advantages and disadvantages, and the choice depends on the specific circumstances. This post was last edited by zfc318 on 2009-2-23 15:24]

It’s for sealing covers to control the odor in sewage treatment plants; does anyone know about this or have experience with it? :loveliness:

Pulling the collector cover to the biological filter should be sufficient

Sealing and covering are required to control the odors in sewage treatment plants; it’s worth learning about this
