How do companies deal with the odorous gases generated during the production process?
Thread Content
Many chemical, paper and other companies will inevitably produce odorous gases during their production processes. What methods do each company adopt to deal with it, and what is the effect? I hope you can introduce it in more detail.
The non-condensable gas at the top of the vacuum tower in the refinery has a foul odor, especially in units that use vacuum pumps. Once repaired, the smell will not be removed for several days. We introduce this exhaust gas into the combustion furnace for incineration treatment, which not only saves fuel but also reduces environmental pollution.
The more adsorption treatments are used, the better the effect will be, but the collection will be more difficult.
From the experience of sewage plants, adsorption is effective, but the effects vary greatly in different regions, and the reasons are quite complex.
The reasons for protection are complex, but the reliability is achieved by absorbing, washing or burning.
The odor contains hydrogen sulfide, and direct combustion will produce acidic substances, which will damage the boiler. Someone has calculated that there are financial risks. I don’t know if it has been considered.
Hydrogen sulfide has a smell with just a few PPVs. In terms of adsorption, considering the adsorption equilibrium, it may not be good. And what to do if it's blocked?

Paper making is mainly difficult to collect. Once this problem is solved, it will be solved. At present, there seems to be no good solution, so the construction of small paper mills is currently restricted.
PTEF membrane can be added as a cover to collect, if the pollution surface is not large.
Collection pipelines in each production site---filtration---acid washing---alkali washing---direct emptying
Biological filtration currently resolves 90% of volatile organic gases and hydrogen sulfide. You can download information from my space
