Urgently seeking domestic companies that specialize in the incineration of acidic organic waste gases

What is the content of combustible components in this? If the concentration is high, catalytic combustion can be used; if it’s too low, other methods should be employed for treatment. Using combustion for low concentrations requires a significant amount of energy, and 10,000 cubic meters of gas isn’t a large volume either. Depending on the specific circumstances, methods such as activated carbon adsorption, chemical washing or spraying, plasma, and photocatalytic oxidation can be selected.

Thank you for your support, boss. The process for verification in the previous stage has been basically determined: burning -> preheating and recovery -> acid removal and dust removal. Now I’m looking for a reputable company to carry out this work!

For acidic gases like LZ, most manufacturers are capable of handling them in combustion furnaces; the main challenge is to carry out proper anti-corrosion measures, and then there aren’t many issues. However, the treatment of flue gases after combustion is a difficult problem that not many manufacturers can handle. Therefore, LZ should pay the most attention to air pollution control.

For organic waste gases containing hydrogen chloride and hydrogen fluoride, we use thermal incineration or catalytic incineration processes for treatment. Since the temperature of the waste gases emitted by your company is around 250 degrees, the residual heat from the reaction is recovered before the gases are sent to an alkaline scrubber for further treatment. Such waste gases are similar to those generated in PTA production. Our extensive experience in similar projects and our excellent engineering capabilities form the basis for our cooperation: wangbochao@shdonghua.com

Shanghai Doctor High could be considered.

Thermal incineration or catalytic incineration are the correct solutions

First, adsorption with activated carbon is carried out, followed by concentration and desorption, and then catalytic combustion. The heat generated from the combustion is reused for the desorption of the activated carbon. Our company has already developed mature techniques for this process.

The process of incineration → preheating and recovery → acid removal and dust removal. The owner’s plan is quite thorough, but the concentration of the combustible components is unknown; if the concentration is not high, adsorption and concentration should be used first. In that case, it is recommended to follow the process of preheating and recovery → acid removal and dust removal → incineration → preheating and recovery, which adds an additional step.

Organic matter can be burned in an incinerator ； Washing towers can be used for HCl and similar substances ； After incineration, metals form fine particles; conventional filtration is not sufficient to handle them, and electrostatic dust removal must be used. Catalytic methods definitely won’t work! Never consider catalysis! Heavy metals are typical catalyst poisons. Get in touch with Ceilcote Company – they have extensive experience and a track record in handling waste gas treatment systems of this type. http://www.ceilcoteapc.com/contactus_globaloffices.html mailto: 1china@ceilcoteapc.com Ceilcote Air Pollution Control (Shanghai) Co., Ltd., Room 2909, Jing’an China Tower, 1701 West Beijing Road, Shanghai 200040, P.R.

I agree with the view above; the halogens and metal elements present in waste gases are substances that can easily poison catalysts. If combustion is used, it is necessary to thoroughly analyze the composition and properties of the metal oxides resulting from combustion, in order to avoid causing damage to the incinerator and the subsequent preheating and recovery systems.

13# haiyueep.cn I guess the 10 million you mentioned at the beginning would be enough to scare away 90% of people, haha.

Investment and operating costs are much lower. For exhaust gas at over 200 degrees, gas-to-gas heat exchange can be considered to recover some of the heat

The exhaust gas temperature is too high; adsorption concentration is definitely not an option. Regenerative combustion seems to be a more reasonable approach. However, in China, there are few systems that can achieve a treatment efficiency of 99% or higher

What are the organometallics in exhaust gases? When using biological filtration, it must be taken into account that heavy metals can also kill microorganisms. What are the levels of HCl and HF? The humidity must be adjusted before the exhaust gas enters the biological filter; a too low pH value can corrode the microbes. The amount of exhaust gas is too small, and the 250°C temperature doesn’t allow for much heat recovery, so it may not be cost-effective. RTO is also not very suitable, as the exhaust gas contains particulates that can clog the packing. At high temperatures, if a concentrator is used, it is necessary to cool down the material first, as well as to carry out microfiltration; otherwise, the pores of the adsorbent will also be quickly blocked by particles. So, the process established by the original poster is still more appropriate. It would be better to make a judgment if more detailed information on ingredients and emission factors could be provided.

Alkali washing is required beforehand to lower the temperature and remove the acid at the same time. Strict control of pH value is required in wastewater treatment. But biological filtration is not a problem; in fact, most bacteria are suitable for surviving in acidic conditions.

It is recommended to try RTO; it has low operating costs, though the installation cost is relatively high. There are already a few companies that do this well
